# Fast-ThinkAct checkpoints

Archive of seven Fast-ThinkAct experiment checkpoint directories:
`policy_ftc`, `policy_rdt`, `vlm_cot_sft_nl`, `vlm_student`,
`vlm_student_nl`, `vlm_teacher`, and `vlm_teacher_nl`.

Each model's files are preserved in its original subdirectory. Download a
specific subdirectory and use it with the matching Fast-ThinkAct code and configuration.
This archive does not include the separate pretrained `weights` directory or frame-depth data.

The VLM experiments use the Qwen2.5-VL architecture; upstream model license
terms continue to apply. The policy experiments use RDT. This archive does
not assign a new blanket license to the included models.

`checkpoint_manifest.json` records the size and SHA256 of every source file.
Uploaded files were verified against Hub file metadata. Local originals were retained.
