Griffin Alpha-S

An AI model: a vision-language-action model (VLA) takes camera images and an instruction and turns them into movements for a robot. This page describes the software, not a robot.

How to read the figures

50HzA: The letter in the grey square after a figure points to the source the figure came from. Pages with several sources carry several letters.

What the data labels mean

Versions and notes in the key figures (6)

Model type

Developer wording: "Griffin Alpha-S is a vision-language-action (VLA) model by" Griffin Labs.

Controls

Blog post: "One set of weights supports multiple robots and both joint-space and end-effector actions." "One set of released Griffin Alpha-S weights running CleanBench on bimanual Piper arms."

Inputs

Repository README: "Both predict a 50-step action chunk from up to three camera images, the proprioceptive state, and a language instruction". Proprioceptive state = robot state.

Access

Blog post: "Open-weights release, September 2026"; the weights are downloaded with the lerobot tools.

Parameters

Note Griffin Labs gives one number for one part: "a 910M-parameter flow-matching action expert attached layer-by-layer (mixture-of-transformers) to a Qwen3-VL-4B backbone".

Base model

Model card header: "base_model: Qwen/Qwen3-VL-4B-Instruct".

The letter points to the source at the foot of the page. Fields without a figure are dashed: the developer does not state them — that is not the same as zero, and not the same as no.
Field	Value	Source and caveats
Input and output
Model type	`vision-language-action`	A Developer wording: "Griffin Alpha-S is a vision-language-action (VLA) model by" Griffin Labs.
Inputs	`camera` `language` `robot state`	A Repository README: "Both predict a 50-step action chunk from up to three camera images, the proprioceptive state, and a language instruction". Proprioceptive state = robot state.
Controls	`arms and hands`	B Blog post: "One set of weights supports multiple robots and both joint-space and end-effector actions." "One set of released Griffin Alpha-S weights running CleanBench on bimanual Piper arms."
Degrees of freedom controlled	not stated	Note Model card: the base uses a "canonical 32-dimensional action vector", with each embodiment's actions in the leading slots; this is the action width, not a count of controlled joints. ⁠C
Size and speed
Parameters	not stated	Note Griffin Labs gives one number for one part: "a 910M-parameter flow-matching action expert attached layer-by-layer (mixture-of-transformers) to a Qwen3-VL-4B backbone". ⁠C

Openness
Access	open download	B Blog post: "Open-weights release, September 2026"; the weights are downloaded with the lerobot tools.
License	CC BY-NC-SA 4.0	C Model card header for the weights: "license: cc-by-nc-sa-4.0". "The plugin code is Apache-2.0."
Free or paid	open, non-commercial only	C Weights licence, model card header: "license: cc-by-nc-sa-4.0".
The developer’s own claims
Learns new tasks	needs retraining	C Developer claim: the pre-trained base is "meant as the starting point for fine-tuning on your own robot".
Works across robots	yes	B Developer claim: "One set of weights supports multiple robots". Yes only if the developer itself says the model runs on different robot models, for example robots from two manufacturers or two of one manufacturer’s models. Several units of the same robot do not count.

Not stated: Control rate, On robot or cloud

Notes

Griffin Labs calls Griffin Alpha a robot foundation model and releases its open core, Griffin Alpha-S.
Griffin Labs published the open weights in September 2026.
The Griffin Labs site is signed Griffin Labs Pte. Ltd. and lists its open roles in Singapore.
