openvla

openvla is a skill for Claude Code, Codex from nebius/nebius-physical-ai. It costs 44 tokens per session (383 once invoked), scanned A, original, Apache-2.0.

A workbench skill for OpenVLA, a vision-language-action model tool used to plan fine-tuning, serving, and evaluation. Its train, serve, and evaluation stages are currently placeholders that validate arguments but do not run the underlying pipeline.

In plain words
What is it for?
Use it to prepare OpenVLA-OFT training, serving, or evaluation jobs in the npa workbench. It is useful for interface and workflow validation while the actual pipeline is being implemented.
Why use it?
It documents the intended command-line, Python, and workflow interfaces without implying that training or serving is already available. The base model is retrieved from the Hugging Face cache rather than included in the project.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

openvla scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 28d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

OpenVLA

OpenVLA is the vision-language-action tool for fine-tuning, serving, and evaluating OpenVLA policies (OpenVLA-OFT recipe) in npa.

The three core stages (train, serve, eval) are currently stubs: they expose the intended argument signatures but exit with a clear "not yet implemented" message until the OpenVLA-OFT fine-tuning pipeline lands (tracking issue nebius/nebius-physical-ai#500). The base model (default openvla/openvla-7b) is resolved at runtime through the HF Hub cache via npa.workbench.model_access — weights are never bundled in the repo or image.

Interfaces

  • CLI: npa workbench openvla <train|serve|eval> --help
  • Python SDK: npa.sdk.workbench.openvla (train, serve, eval)
  • Workflow module: npa.workflows.byof.openvla_pipeline (argument validation, upstream argv planning, argparse entrypoint)

Conventions

  • The CLI lives at npa.cli.workbench.openvla (multi-command package form for new tools); the SDK surface lives at npa.sdk.workbench.openvla.
  • The train stage is the headline openvla/train three-tier contract (CLI <-> SDK <-> workflows/testing/openvla-train.yaml); serve and eval remain public-reusable sibling toolRefs.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

openvla is a skill published in the GitHub repository nebius/nebius-physical-ai (50 stars, last pushed today), licensed Apache-2.0. It adds 44 tokens to every session and 383 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-24.
