What it is¶

An open-source instruction-guided video editing model for Wan users who change objects, style, or text in a video while keeping motion.

• Semantic anchoring plans edits across keyframes.
• Motion alignment preserves temporal dynamics.
• SAMA-14B checkpoint and an official ComfyUI workflow are available.

Requires Linux, an NVIDIA GPU, Python 3.10, a CUDA 12.1-compatible environment, and Wan2.1-T2V-14B. This is a local inference stack on top of Wan, not a hosted service.

Development line¶

• 2026-03-20 — SAMA public project, source, and model resources were linked. On 2026-03-20, a dated SAMA message linked the project's public website, source repository, and the Hugging Face page for SAMA-14B. These links establish that the three public resources were associated with SAMA on that date, without establishing further claims about the model or project.

What changed¶

• 2026-03-20 — SAMA paper published; preprint submitted on 2026-03-19 with 24 pages and 12 figures.
• 2026-03-21 — SAMA-14B checkpoint released; SAMA-5B still marked as Coming soon.
• 2026-03-24 — Official SAMA-ComfyUI workflow opened.
• 2026-06-20 — SAMA accepted to ECCV 2026.
• 2026-06-26 — SAMA-edit-filtered-1M metadata set published.

How to use this¶

As of 2026-03-20, we use the linked SAMA website, source repository, and SAMA-14B model page as starting points for evaluation, verifying capabilities, licensing, and usage requirements from those resources before adoption.

1. Clone the repository, create a Python 3.10 environment, and install dependencies. — https://github.com/Cynthiazxy123/SAMA
2. Download SAMA-14B and prepare the full local Wan2.1-T2V-14B directory. — https://huggingface.co/syxbb/SAMA-14B
3. Set MODEL_ROOT, STATE_DICT, SRC_VIDEO, PROMPT, and OUTPUT_DIR in infer_sh/run_sama.sh, then run the script. — https://github.com/Cynthiazxy123/SAMA
4. For a node-based workflow, use the official ComfyUI integration with the Wan base model and SAMA-14B. — https://github.com/Cynthiazxy123/SAMA

Best practices¶

• Verify the base Wan2.1-T2V-14B directory is complete: the script intentionally stops if files are missing. — https://github.com/Cynthiazxy123/SAMA
• Use the source FPS; set --fps explicitly when it is missing. — https://github.com/Cynthiazxy123/SAMA
• Account for automatic padding of input frames to the Wan 4k+1 requirement. — https://github.com/Cynthiazxy123/SAMA

Superseded by this¶

• 2026-03-20 — paper-only state: SAMA-14B is available as of 2026-03-21, and the official ComfyUI workflow is available as of 2026-03-24.

Still unknown¶

• Official materials do not provide measured VRAM, inference speed, or supported resolutions. Hardware planning requires separate testing of the configuration and workflow.

Agent brief¶

• Subject: project:sama, thread sama, 1 dated events 2026-03-20 → 2026-03-20.
• Practical note: As of 2026-03-20, practitioners can use the linked SAMA website, source repository, and SAMA-14B model page as the primary starting points for evaluation, while verifying capabilities, licensing, and usage requirements from those resources before adoption.
• Confidence: high. Dated supersedes above are the authority for what is obsolete.
