| Input and output | ||
| Model type | vision-language-action | Hugging Face model card tag: "vision-language-action-model". B |
| Inputs | camera language robot state | Technical report: the multi-view observation "is encoded into visual tokens via the integrated vision encoder, while language instructions" are converted into text tokens. The action expert is conditioned on these features "together with the proprioceptive state". A |
| Controls | arms and hands | Technical report: "the action expert predicts a target action chunk". The real-robot tests: "These platforms cover diverse bimanual manipulation capabilities". A |
| Degrees of freedom controlled | not stated | |
| Size and speed | ||
| Parameters | 3.2B | Technical report, table of the 3B release (the main checkpoint InternVLA-A1-3B): "InternVLA-A1 (3B) 3.2B Qwen3-VL (2.13B)". The 2B scale: "InternVLA-A1 (2B) 1.8B InternVL3 (0.94B)". A |
| Control rate | 13Hz | Model inference speed on one GPU, not motor control: "both InternVLA-A1 (2B) and InternVLA-A1 (3B) run at approximately 13 Hz with torch.compile on one RTX 4090 GPU". A |
| Where it runs and what it is built on | ||
| On robot or cloud | not stated | Note The report measures speed on a GPU: "both InternVLA-A1 (2B) and InternVLA-A1 (3B) run at approximately 13 Hz with torch.compile on one RTX 4090 GPU". A |
| Base model | Qwen3-VL | Technical report: the 3B release uses Qwen3-VL as understanding expert ("InternVLA-A1 (3B) 3.2B Qwen3-VL (2.13B)"); the 2B release uses InternVL3. Abstract: "Building upon InternVL3 and Qwen3-VL, we instantiate InternVLA-A1 at 2B and 3B parameter scales." A |

| Licence terms | CC BY-NC-SA 4.0 | Model card header: "license: cc-by-nc-sa-4.0". "All the code within this repo are under CC BY-NC-SA 4.0." B |

| The developer’s own claims | ||
| Learns new tasks | needs retraining | Developer claim: training ends with "a large-scale pre-training stage on heterogeneous datasets, followed by a task-specific post-training stage". A |
| Works across robots | yes | Developer claim: "We benchmark the policies on three physical robot embodiments: Agibot Genie-1, ARX Lift-2, and ARX AC One". A 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. |
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.
Notes
- The InternVLA-A1 paper is signed Shanghai AI Laboratory.
- The developers have since published a successor, InternVLA-A1.5, in the same repository.
