## FFmpeg - [FFMPEG License](https://github.com/FFmpeg/FFmpeg/blob/master/LICENSE.md)

   ```
   # License

   Most files in FFmpeg are under the GNU Lesser General Public License version 2.1
   or later (LGPL v2.1+). Read the file `COPYING.LGPLv2.1` for details. Some other
   files have MIT/X11/BSD-style licenses. In combination the LGPL v2.1+ applies to
   FFmpeg.

   Some optional parts of FFmpeg are licensed under the GNU General Public License
   version 2 or later (GPL v2+). See the file `COPYING.GPLv2` for details. None of
   these parts are used by default, you have to explicitly pass `--enable-gpl` to
   configure to activate them. In this case, FFmpeg's license changes to GPL v2+.

   Specifically, the GPL parts of FFmpeg are:

   - libpostproc
   - optional x86 optimization in the files
       - `libavcodec/x86/flac_dsp_gpl.asm`
       - `libavcodec/x86/idct_mmx.c`
       - `libavfilter/x86/vf_removegrain.asm`
   - the following building and testing tools
       - `compat/solaris/make_sunver.pl`
       - `doc/t2h.pm`
       - `doc/texi2pod.pl`
       - `libswresample/tests/swresample.c`
       - `tests/checkasm/*`
       - `tests/tiny_ssim.c`
   - the following filters in libavfilter:
       - `signature_lookup.c`
       - `vf_blackframe.c`
       - `vf_boxblur.c`
       - `vf_colormatrix.c`
       - `vf_cover_rect.c`
       - `vf_cropdetect.c`
       - `vf_delogo.c`
       - `vf_eq.c`
       - `vf_find_rect.c`
       - `vf_fspp.c`
       - `vf_histeq.c`
       - `vf_hqdn3d.c`
       - `vf_kerndeint.c`
       - `vf_lensfun.c` (GPL version 3 or later)
       - `vf_mcdeint.c`
       - `vf_mpdecimate.c`
       - `vf_nnedi.c`
       - `vf_owdenoise.c`
       - `vf_perspective.c`
       - `vf_phase.c`
       - `vf_pp.c`
       - `vf_pp7.c`
       - `vf_pullup.c`
       - `vf_repeatfields.c`
       - `vf_sab.c`
       - `vf_signature.c`
       - `vf_smartblur.c`
       - `vf_spp.c`
       - `vf_stereo3d.c`
       - `vf_super2xsai.c`
       - `vf_tinterlace.c`
       - `vf_uspp.c`
       - `vf_vaguedenoiser.c`
       - `vsrc_mptestsrc.c`

   Should you, for whatever reason, prefer to use version 3 of the (L)GPL, then
   the configure parameter `--enable-version3` will activate this licensing option
   for you. Read the file `COPYING.LGPLv3` or, if you have enabled GPL parts,
   `COPYING.GPLv3` to learn the exact legal terms that apply in this case.

   There are a handful of files under other licensing terms, namely:

   * The files `libavcodec/jfdctfst.c`, `libavcodec/jfdctint_template.c` and
     `libavcodec/jrevdct.c` are taken from libjpeg, see the top of the files for
     licensing details. Specifically note that you must credit the IJG in the
     documentation accompanying your program if you only distribute executables.
     You must also indicate any changes including additions and deletions to
     those three files in the documentation.
   * `tests/reference.pnm` is under the expat license.

   ## External libraries

   FFmpeg can be combined with a number of external libraries, which sometimes
   affect the licensing of binaries resulting from the combination.

   ### Compatible libraries

   The following libraries are under GPL version 2:
   - avisynth
   - frei0r
   - libcdio
   - libdavs2
   - librubberband
   - libvidstab
   - libx264
   - libx265
   - libxavs
   - libxavs2
   - libxvid

   When combining them with FFmpeg, FFmpeg needs to be licensed as GPL as well by
   passing `--enable-gpl` to configure.

   The following libraries are under LGPL version 3:
   - gmp
   - libaribb24
   - liblensfun

   When combining them with FFmpeg, use the configure option `--enable-version3` to
   upgrade FFmpeg to the LGPL v3.

   The VMAF, mbedTLS, RK MPI, OpenCORE and VisualOn libraries are under the Apache License
   2.0. That license is incompatible with the LGPL v2.1 and the GPL v2, but not with
   version 3 of those licenses. So to combine these libraries with FFmpeg, the
   license version needs to be upgraded by passing `--enable-version3` to configure.

   The smbclient library is under the GPL v3, to combine it with FFmpeg,
   the options `--enable-gpl` and `--enable-version3` have to be passed to
   configure to upgrade FFmpeg to the GPL v3.

   ### Incompatible libraries

   There are certain libraries you can combine with FFmpeg whose licenses are not
   compatible with the GPL and/or the LGPL. If you wish to enable these
   libraries, even in circumstances that their license may be incompatible, pass
   `--enable-nonfree` to configure. This will cause the resulting binary to be
   unredistributable.

   The Fraunhofer FDK AAC and OpenSSL libraries are under licenses which are
   incompatible with the GPLv2 and v3. To the best of our knowledge, they are
   compatible with the LGPL.

         "Work" shall mean the work of authorship, whether in Source or
         Object form, made available under the License, as indicated by a
         copyright notice that is included in or attached to the work
         (an example is provided in the Appendix below).

         "Derivative Works" shall mean any work, whether in Source or Object
         form, that is based on (or derived from) the Work and for which the
         editorial revisions, annotations, elaborations, or other modifications
         represent, as a whole, an original work of authorship. For the purposes
         of this License, Derivative Works shall not include works that remain
         separable from, or merely link (or bind by name) to the interfaces of,
         the Work and Derivative Works thereof.

         "Contribution" shall mean any work of authorship, including
         the original version of the Work and any modifications or additions
         to that Work or Derivative Works thereof, that is intentionally
         submitted to Licensor for inclusion in the Work by the copyright owner
         or by an individual or Legal Entity authorized to submit on behalf of
         the copyright owner. For the purposes of this definition, "submitted"
         means any form of electronic, verbal, or written communication sent
         to the Licensor or its representatives, including but not limited to
         communication on electronic mailing lists, source code control systems,
         and issue tracking systems that are managed by, or on behalf of, the

         "Contributor" shall mean Licensor and any individual or Legal Entity
         on behalf of whom a Contribution has been received by Licensor and
         subsequently incorporated within the Work.

      2. Grant of Copyright License. Subject to the terms and conditions of
         this License, each Contributor hereby grants to You a perpetual,
         worldwide, non-exclusive, no-charge, royalty-free, irrevocable
         copyright license to reproduce, prepare Derivative Works of,
         publicly display, publicly perform, sublicense, and distribute the
         Work and such Derivative Works in Source or Object form.

      3. Grant of Patent License. Subject to the terms and conditions of
         this License, each Contributor hereby grants to You a perpetual,
         worldwide, non-exclusive, no-charge, royalty-free, irrevocable
         (except as stated in this section) patent license to make, have made,
         use, offer to sell, sell, import, and otherwise transfer the Work,
         where such license applies only to those patent claims licensable
         by such Contributor that are necessarily infringed by their
         Contribution(s) alone or by combination of their Contribution(s)
         with the Work to which such Contribution(s) was submitted. If You
         institute patent litigation against any entity (including a
         cross-claim or counterclaim in a lawsuit) alleging that the Work
         or a Contribution incorporated within the Work constitutes direct
         or contributory patent infringement, then any patent licenses
         granted to You under this License for that Work shall terminate
         as of the date such litigation is filed.

      4. Redistribution. You may reproduce and distribute copies of the
         Work or Derivative Works thereof in any medium, with or without
         modifications, and in Source or Object form, provided that You
         meet the following conditions:

         (a) You must give any other recipients of the Work or
             Derivative Works a copy of this License; and

         (b) You must cause any modified files to carry prominent notices
             stating that You changed the files; and

         (c) You must retain, in the Source form of any Derivative Works
             that You distribute, all copyright, patent, trademark, and
             attribution notices from the Source form of the Work,
             excluding those notices that do not pertain to any part of
             the Derivative Works; and

         (d) If the Work includes a "NOTICE" text file as part of its
             distribution, then any Derivative Works that You distribute must
             include a readable copy of the attribution notices contained
             within such NOTICE file, excluding those notices that do not
             pertain to any part of the Derivative Works, in at least one
             of the following places: within a NOTICE text file distributed
             as part of the Derivative Works; within the Source form or
             documentation, if provided along with the Derivative Works; or,
             within a display generated by the Derivative Works, if and
             wherever such third-party notices normally appear. The contents
             of the NOTICE file are for informational purposes only and
             do not modify the License. You may add Your own attribution
             notices within Derivative Works that You distribute, alongside
             or as an addendum to the NOTICE text from the Work, provided
             that such additional attribution notices cannot be construed
             as modifying the License.

         You may add Your own copyright statement to Your modifications and
         may provide additional or different license terms and conditions
         for use, reproduction, or distribution of Your modifications, or
         for any such Derivative Works as a whole, provided Your use,
         reproduction, and distribution of the Work otherwise complies with
         the conditions stated in this License.

      5. Submission of Contributions. Unless You explicitly state otherwise,
         any Contribution intentionally submitted for inclusion in the Work
         by You to the Licensor shall be under the terms and conditions of
         this License, without any additional terms or conditions.
         Notwithstanding the above, nothing herein shall supersede or modify
         the terms of any separate license agreement you may have executed
         with Licensor regarding such Contributions.

      6. Trademarks. This License does not grant permission to use the trade
         names, trademarks, service marks, or product names of the Licensor,
         except as required for reasonable and customary use in describing the
         origin of the Work and reproducing the content of the NOTICE file.

      7. Disclaimer of Warranty. Unless required by applicable law or
         agreed to in writing, Licensor provides the Work (and each
         Contributor provides its Contributions) on an "AS IS" BASIS,
         WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
         implied, including, without limitation, any warranties or conditions
         of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
         PARTICULAR PURPOSE. You are solely responsible for determining the
         appropriateness of using or redistributing the Work and assume any
         risks associated with Your exercise of permissions under this License.

      8. Limitation of Liability. In no event and under no legal theory,
         whether in tort (including negligence), contract, or otherwise,
         unless required by applicable law (such as deliberate and grossly
         negligent acts) or agreed to in writing, shall any Contributor be
         liable to You for damages, including any direct, indirect, special,
         incidental, or consequential damages of any character arising as a
         result of this License or out of the use or inability to use the
         Work (including but not limited to damages for loss of goodwill,
         work stoppage, computer failure or malfunction, or any and all
         other commercial damages or losses), even if such Contributor
         has been advised of the possibility of such damages.

      9. Accepting Warranty or Additional Liability. While redistributing
         the Work or Derivative Works thereof, You may choose to offer,
         and charge a fee for, acceptance of support, warranty, indemnity,
         or other liability obligations and/or rights consistent with this
         License. However, in accepting such obligations, You may act only
         on Your own behalf and on Your sole responsibility, not on behalf
         of any other Contributor, and only if You agree to indemnify,
         defend, and hold each Contributor harmless for any liability
         incurred by, or claims asserted against, such Contributor by reason
         of your accepting any such warranty or additional liability.

      END OF TERMS AND CONDITIONS

         form, that is based on (or derived from) the Work and for which the
         editorial revisions, annotations, elaborations, or other modifications
         represent, as a whole, an original work of authorship. For the purposes
         of this License, Derivative Works shall not include works that remain
         separable from, or merely link (or bind by name) to the interfaces of,
         the Work and Derivative Works thereof.

         "Contribution" shall mean any work of authorship, including
         the original version of the Work and any modifications or additions
         to that Work or Derivative Works thereof, that is intentionally
         submitted to Licensor for inclusion in the Work by the copyright owner
         or by an individual or Legal Entity authorized to submit on behalf of
         the copyright owner. For the purposes of this definition, "submitted"
         means any form of electronic, verbal, or written communication sent
         to the Licensor or its representatives, including but not limited to
         communication on electronic mailing lists, source code control systems,
         and issue tracking systems that are managed by, or on behalf of, the
         Licensor for the purpose of discussing and improving the Work, but
         excluding communication that is conspicuously marked or otherwise
         designated in writing by the copyright owner as "Not a Contribution."

         "Contributor" shall mean Licensor and any individual or Legal Entity
         on behalf of whom a Contribution has been received by Licensor and
         subsequently incorporated within the Work.

      2. Grant of Copyright License. Subject to the terms and conditions of
         this License, each Contributor hereby grants to You a perpetual,
         worldwide, non-exclusive, no-charge, royalty-free, irrevocable
         copyright license to reproduce, prepare Derivative Works of,
         publicly display, publicly perform, sublicense, and distribute the
         Work and such Derivative Works in Source or Object form.

      3. Grant of Patent License. Subject to the terms and conditions of
         this License, each Contributor hereby grants to You a perpetual,
         worldwide, non-exclusive, no-charge, royalty-free, irrevocable
         (except as stated in this section) patent license to make, have made,
         use, offer to sell, sell, import, and otherwise transfer the Work,
         where such license applies only to those patent claims licensable
         by such Contributor that are necessarily infringed by their
         Contribution(s) alone or by combination of their Contribution(s)
         with the Work to which such Contribution(s) was submitted. If You
         institute patent litigation against any entity (including a
         cross-claim or counterclaim in a lawsuit) alleging that the Work
         or a Contribution incorporated within the Work constitutes direct
         or contributory patent infringement, then any patent licenses
         granted to You under this License for that Work shall terminate
         as of the date such litigation is filed.

      4. Redistribution. You may reproduce and distribute copies of the
         Work or Derivative Works thereof in any medium, with or without
         modifications, and in Source or Object form, provided that You
         meet the following conditions:

         (a) You must give any other recipients of the Work or
             Derivative Works a copy of this License; and

         (b) You must cause any modified files to carry prominent notices
             stating that You changed the files; and

         (c) You must retain, in the Source form of any Derivative Works
             that You distribute, all copyright, patent, trademark, and
             attribution notices from the Source form of the Work,
             excluding those notices that do not pertain to any part of
             the Derivative Works; and

         (d) If the Work includes a "NOTICE" text file as part of its
             distribution, then any Derivative Works that You distribute must
             include a readable copy of the attribution notices contained
             within such NOTICE file, excluding those notices that do not
             pertain to any part of the Derivative Works, in at least one
             of the following places: within a NOTICE text file distributed
             as part of the Derivative Works; within the Source form or
             documentation, if provided along with the Derivative Works; or,
             within a display generated by the Derivative Works, if and
             wherever such third-party notices normally appear. The contents
             of the NOTICE file are for informational purposes only and
             do not modify the License. You may add Your own attribution
             notices within Derivative Works that You distribute, alongside
             or as an addendum to the NOTICE text from the Work, provided
             that such additional attribution notices cannot be construed
             as modifying the License.

         You may add Your own copyright statement to Your modifications and
         may provide additional or different license terms and conditions
         for use, reproduction, or distribution of Your modifications, or
         for any such Derivative Works as a whole, provided Your use,
         reproduction, and distribution of the Work otherwise complies with
         the conditions stated in this License.

      5. Submission of Contributions. Unless You explicitly state otherwise,
         any Contribution intentionally submitted for inclusion in the Work
         by You to the Licensor shall be under the terms and conditions of
         this License, without any additional terms or conditions.
         Notwithstanding the above, nothing herein shall supersede or modify
         the terms of any separate license agreement you may have executed
         with Licensor regarding such Contributions.

      6. Trademarks. This License does not grant permission to use the trade
         names, trademarks, service marks, or product names of the Licensor,
         except as required for reasonable and customary use in describing the
         origin of the Work and reproducing the content of the NOTICE file.

      7. Disclaimer of Warranty. Unless required by applicable law or
         agreed to in writing, Licensor provides the Work (and each
         Contributor provides its Contributions) on an "AS IS" BASIS,
         WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
         implied, including, without limitation, any warranties or conditions
         of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
         PARTICULAR PURPOSE. You are solely responsible for determining the
         appropriateness of using or redistributing the Work and assume any
         risks associated with Your exercise of permissions under this License.

      8. Limitation of Liability. In no event and under no legal theory,
         whether in tort (including negligence), contract, or otherwise,
         unless required by applicable law (such as deliberate and grossly
         negligent acts) or agreed to in writing, shall any Contributor be
         liable to You for damages, including any direct, indirect, special,
         incidental, or consequential damages of any character arising as a
         result of this License or out of the use or inability to use the
         Work (including but not limited to damages for loss of goodwill,
         work stoppage, computer failure or malfunction, or any and all
         other commercial damages or losses), even if such Contributor
         has been advised of the possibility of such damages.

      9. Accepting Warranty or Additional Liability. While redistributing
         the Work or Derivative Works thereof, You may choose to offer,
         and charge a fee for, acceptance of support, warranty, indemnity,
         or other liability obligations and/or rights consistent with this
         License. However, in accepting such obligations, You may act only
         on Your own behalf and on Your sole responsibility, not on behalf
         of any other Contributor, and only if You agree to indemnify,
         defend, and hold each Contributor harmless for any liability
         incurred by, or claims asserted against, such Contributor by reason
         of your accepting any such warranty or additional liability.

         form, that is based on (or derived from) the Work and for which the
         editorial revisions, annotations, elaborations, or other modifications

         whether in tort (including negligence), contract, or otherwise,

         transformation or translation of a Source form, including but
         not limited to compiled object code, generated documentation,

         Object form, made available under the License, as indicated by a
         copyright notice that is included in or attached to the work

         "Derivative Works" shall mean any work, whether in Source or Object
         form, that is based on (or derived from) the Work and for which the
         editorial revisions, annotations, elaborations, or other modifications
         represent, as a whole, an original work of authorship. For the purposes
         of this License, Derivative Works shall not include works that remain
         separable from, or merely link (or bind by name) to the interfaces of,
         the Work and Derivative Works thereof.

         "Contribution" shall mean any work of authorship, including
         the original version of the Work and any modifications or additions

         submitted to Licensor for inclusion in the Work by the copyright owner
         or by an individual or Legal Entity authorized to submit on behalf of
         the copyright owner. For the purposes of this definition, "submitted"

         to the Licensor or its representatives, including but not limited to
         communication on electronic mailing lists, source code control systems,

         "Contributor" shall mean Licensor and any individual or Legal Entity
         on behalf of whom a Contribution has been received by Licensor and
         subsequently incorporated within the Work.

      2. Grant of Copyright License. Subject to the terms and conditions of
         this License, each Contributor hereby grants to You a perpetual,
         worldwide, non-exclusive, no-charge, royalty-free, irrevocable
         copyright license to reproduce, prepare Derivative Works of,
         publicly display, publicly perform, sublicense, and distribute the
         Work and such Derivative Works in Source or Object form.

      3. Grant of Patent License. Subject to the terms and conditions of
         this License, each Contributor hereby grants to You a perpetual,
         worldwide, non-exclusive, no-charge, royalty-free, irrevocable
         (except as stated in this section) patent license to make, have made,
         use, offer to sell, sell, import, and otherwise transfer the Work,
         where such license applies only to those patent claims licensable
         by such Contributor that are necessarily infringed by their
         Contribution(s) alone or by combination of their Contribution(s)
         with the Work to which such Contribution(s) was submitted. If You
         institute patent litigation against any entity (including a
         cross-claim or counterclaim in a lawsuit) alleging that the Work
         or a Contribution incorporated within the Work constitutes direct
         or contributory patent infringement, then any patent licenses
         granted to You under this License for that Work shall terminate
         as of the date such litigation is filed.

      4. Redistribution. You may reproduce and distribute copies of the
         Work or Derivative Works thereof in any medium, with or without
         modifications, and in Source or Object form, provided that You
         meet the following conditions:

         (a) You must give any other recipients of the Work or
             Derivative Works a copy of this License; and

         (b) You must cause any modified files to carry prominent notices
             stating that You changed the files; and

         (c) You must retain, in the Source form of any Derivative Works
             that You distribute, all copyright, patent, trademark, and
             attribution notices from the Source form of the Work,
             excluding those notices that do not pertain to any part of
             the Derivative Works; and

         (d) If the Work includes a "NOTICE" text file as part of its
             distribution, then any Derivative Works that You distribute must
             include a readable copy of the attribution notices contained
             within such NOTICE file, excluding those notices that do not
             pertain to any part of the Derivative Works, in at least one
             of the following places: within a NOTICE text file distributed
             as part of the Derivative Works; within the Source form or
             documentation, if provided along with the Derivative Works; or,
             within a display generated by the Derivative Works, if and
             wherever such third-party notices normally appear. The contents
             of the NOTICE file are for informational purposes only and
             do not modify the License. You may add Your own attribution
             notices within Derivative Works that You distribute, alongside
             or as an addendum to the NOTICE text from the Work, provided
             that such additional attribution notices cannot be construed
             as modifying the License.

         You may add Your own copyright statement to Your modifications and
         may provide additional or different license terms and conditions
         for use, reproduction, or distribution of Your modifications, or
         for any such Derivative Works as a whole, provided Your use,
         reproduction, and distribution of the Work otherwise complies with
         the conditions stated in this License.

      5. Submission of Contributions. Unless You explicitly state otherwise,
         any Contribution intentionally submitted for inclusion in the Work
         by You to the Licensor shall be under the terms and conditions of
         this License, without any additional terms or conditions.
         Notwithstanding the above, nothing herein shall supersede or modify
         the terms of any separate license agreement you may have executed
         with Licensor regarding such Contributions.

      6. Trademarks. This License does not grant permission to use the trade
         names, trademarks, service marks, or product names of the Licensor,
         except as required for reasonable and customary use in describing the
         origin of the Work and reproducing the content of the NOTICE file.

      7. Disclaimer of Warranty. Unless required by applicable law or
         agreed to in writing, Licensor provides the Work (and each
         Contributor provides its Contributions) on an "AS IS" BASIS,
         WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
         implied, including, without limitation, any warranties or conditions
         of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
         PARTICULAR PURPOSE. You are solely responsible for determining the
         appropriateness of using or redistributing the Work and assume any
         risks associated with Your exercise of permissions under this License.

      8. Limitation of Liability. In no event and under no legal theory,
         whether in tort (including negligence), contract, or otherwise,
         unless required by applicable law (such as deliberate and grossly
         negligent acts) or agreed to in writing, shall any Contributor be
         liable to You for damages, including any direct, indirect, special,
         incidental, or consequential damages of any character arising as a
         result of this License or out of the use or inability to use the
         Work (including but not limited to damages for loss of goodwill,
         work stoppage, computer failure or malfunction, or any and all
         other commercial damages or losses), even if such Contributor
         has been advised of the possibility of such damages.

      9. Accepting Warranty or Additional Liability. While redistributing
         the Work or Derivative Works thereof, You may choose to offer,
         and charge a fee for, acceptance of support, warranty, indemnity,
         or other liability obligations and/or rights consistent with this
         License. However, in accepting such obligations, You may act only
         on Your own behalf and on Your sole responsibility, not on behalf
         of any other Contributor, and only if You agree to indemnify,
         defend, and hold each Contributor harmless for any liability
         incurred by, or claims asserted against, such Contributor by reason
         of your accepting any such warranty or additional liability.

## Example Usage

### Inference

Follow the [Cosmos Installation Guide](INSTALL.md) to setup the docker. For inference with the pretrained models, please refer to [Cosmos Diffusion Inference](cosmos1/models/diffusion/README.md) and [Cosmos Autoregressive Inference](cosmos1/models/autoregressive/README.md).

The code snippet below provides a gist of the inference usage.

```bash
PROMPT="A sleek, humanoid robot stands in a vast warehouse filled with neatly stacked cardboard boxes on industrial shelves. \
The robot's metallic body gleams under the bright, even lighting, highlighting its futuristic design and intricate joints. \
A glowing blue light emanates from its chest, adding a touch of advanced technology. The background is dominated by rows of boxes, \
suggesting a highly organized storage system. The floor is lined with wooden pallets, enhancing the industrial setting. \
The camera remains static, capturing the robot's poised stance amidst the orderly environment, with a shallow depth of \
field that keeps the focus on the robot while subtly blurring the background for a cinematic effect."

# Example using 7B model
PYTHONPATH=$(pwd) python cosmos1/models/diffusion/inference/text2world.py \
    --checkpoint_dir checkpoints \
    --diffusion_transformer_dir Cosmos-1.0-Diffusion-7B-Text2World \
    --prompt "$PROMPT" \
    --offload_prompt_upsampler \
    --video_save_name Cosmos-1.0-Diffusion-7B-Text2World
```

# Cosmos Post-training

In the [Cosmos paper](https://research.nvidia.com/publication/2025-01_cosmos-world-foundation-model-platform-physical-ai), we discuss several post-training examples of Cosmos pre-trained World Foundation Models (WFMs) for various Physical AI tasks, including

- General Post-Training: Fine-tune the WFM to generate a target distribution of videos based on the custom dataset. The target distribution could include a specific camera spec or a specific domain such as a factory.
- Instruction Control: Post-trains models for robotic manipulation to predict videos based on textual instructions, enabling robots to visually simulate tasks like folding clothes or picking up objects.
- Action Control: Post-trains models for robotic manipulation to predict the next visual frame based on action vectors, simulating robotic tasks like object handling or movement planning.
- Camera Control: Adds camera pose conditioning to generate 3D-consistent video simulations from single images, enabling joystick-like navigation in virtual environments.
- Multi-View Generation: Post-trains models for autonomous vehicles to generate synchronized multi-view videos from text prompts, simulating driving scenarios with multiple camera perspectives.
- Multi-View Generation with Vehicle Trajectory Control: Extends multi-view generation by incorporating trajectory inputs, enabling precise simulation of driving environments for autonomous vehicles, adhering to specified paths.

Except for the instruction control where the WFM is post-trained on a dataset of instruction-video pairs, all other cases require minor modifications of the network architectures. Post-training tasks will be supported by NeMo Framework. In this initial release, we provide post-training scripts for the general post-training of both diffusion and autorgressive WFMs. Scripts of the other post-training tasks will be provided in a future release.

## Post-training Support Matrix

| Instruction control | Coming soon | Coming soon |
| Action control | Coming soon | Coming soon |
| Camera control | Coming soon | Coming soon |
| Multi-view generation | Coming soon | Coming soon |
| Multi-view generation with vehicle trajectory control | Coming soon | Coming soon |
