A pi05 policy post-trained on real robot data from a 112 container-hour mid-training produced with CEI-2.0. One arm of a four-way comparison: all four share an identical post-training recipe and differ only in which mid-trained prior they start from (mix5, mix10, droid, sim). The input pipeline padded the 18 real joints out to the model's 32 dims before normalising, so the 14 padding dims were normalised along with the real ones. Under quantile normalisation a degenerate padded dim maps to −1 rather than 0. Because pi05 uses discretestateinput, the state is binned into 256 levels and serialised as text, so those dims rendered as "0" (bin 0) instead of "128" (bin 128) — 14 of 32 state values differed and the state string grew by 28 tokens, diverging from any serving stack that pads after normalising. Padding now follows openpi's own order — Normalize first, then PadStatesAndActions — so the…

Compatibility and lineage

Language coverage was not reported.

Base-model lineage was not included.

Parameter count is not a RAM/VRAM requirement. Check precision, quantization, context length and runtime compatibility in the model card; no hardware or API-cost claim is inferred here.

Use and evaluate

Check license terms and access requirements first. Review the model card’s documented loading instructions, evaluations and safety limitations. Benchmark scores are not imported by this directory, and popularity is not an accuracy ranking.

No model weights are downloaded or executed by AltAPIs. Never enable remote model code without reviewing it.
