Model claims are labelled by how we know them: gemma — disclosed, pi-0.5 — disclosed, pi-0.5-DROID — disclosed, pi-0.5-LIBERO — disclosed, pi05_base — disclosed, π₀-FAST — disclosed and π0.5 — disclosed. "Disclosed" means the vendor says so in public; "inferred" means it was derived from documentation, headers or release notes.
Other stack signals: PyTorch and uv.
