Versions and notes in the key figures (6)
Model type
Model card: "EO-1 model is a Vision-Language-Action (VLA) model that adopts a single unified decoder-only transformer"; it is built "for multimodal embodied reasoning and robot control, enabling seamless perception, planning, reasoning, and acting in single model".
Controls
Model card, Output: "Output Type(s): Actions, Language". The real-robot tests are arm and dual-arm manipulation tasks: "Agibot G-1 Long-Horizon Dexterity (4 Tasks)."
Inputs
Model card, Input Type: "Vision: Image Frames, Video"; "State: Robot Proprioception"; "Language Instruction: Text, Pointing, Bounding Box, etc.". Image frames and video = camera, robot proprioception = robot state.
Access
Project page: "EO-1 is released with full openness, including model weights, training code, and all components of the interleaved embodied dataset".
Parameters
Model card: "an open-source unified embodied foundation model comprising 3B parameters".
Base model
Model card: the tokens are processed by the "shared transformer backbone, whose weights are initialized from Qwen2.5-VL"; base model listed as "Qwen/Qwen2.5-VL-3B-Instruct".

| The developer’s own claims | ||
| Learns new tasks | needs retraining | B Developer claim: the long-horizon AgiBot G-1 tasks are learned by fine-tuning: "Specializing fine-tuning is performed using 150 demonstration trajectories per task". |
| Works across robots | yes | B Developer claim: "We evaluate its performance on both short-horizon and long-horizon tasks using different robots, including Franka Panda, WidowX 250 S, Agibot G-1, and Lerobot SO100." 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. |
