EO-1 3B (fabric)

⚠️ Robot policy — needs a matching robot to actuate. This is IPEC-COMMUNITY/EO-1-3B converted to an Apple Core AI .aimodel. Its output is a normalized action chunk for multi_embodiment. Run it on any other robot, or with mismatched calibration / normalization stats, and it emits floats that look valid but actuate garbage — the most dangerous silent-failure mode. It is a base checkpoint: fine-tune on your robot's data before expecting useful behavior.

An Apple Core AI conversion of IPEC-COMMUNITY/EO-1-3B — a robot policy that maps images + proprioceptive state (+ a language instruction, when the model uses one) to a continuous action chunk (flow_matching sampler). Produced by coreai-fabric and indexed by coreai-catalog.

Model facts

Use it — this needs host code you supply

A policy is not a chat model: there is no stock high-level Swift runtime for it. The bundle is the split-export shape — an encode graph (run once per observation) + a denoise_step graph (the host drives it num_steps times) + norm_stats.json (un-normalization). You supply the host loop (the N-step sampler + un-normalization) in Swift. Recommended integration: keep LeRobot's Python RobotClient for the servos/cameras/calibration, and run inference on-device — see the io_contract in the catalog for the exact tensors.

pip install coreai-catalog && coreai-catalog install eo1-3b

Requirements

• Deployment: macOS 27.0+ / iOS 27.0+, Xcode 27+. The asset serializes with minimum_os v27, so the on-device Swift runtime requires macOS/iOS 27+. A Mac on macOS 26 can convert and inspect it but not run it on-device.
• Apple Silicon. A matching robot to actuate (see the banner).

Verification (action parity)

• Gate A (structure): passed — the bundle's layout + metadata were validated on real hardware; the graphs load.
• Gate B (action_parity): passed — unmeasured pending a real conversion + verify on hardware. fabric never fakes a parity number.
• This certifies the export is numerically faithful to the source policy — it does NOT certify real-world task success, embodiment transfer, or closed-loop stability. Closed-loop success-rate eval (LIBERO/ManiSkill): not_run (a separate future gate). Reproduce with coreai-fabric verify.
