Launch
Exact materialization of this validated launch contract: digest-pinned image, pinned model revision, and the audited arguments. Self-contained — required assets are fetched from this registry and verified against their recorded sha256 before mounting. Also available as local-ai run qwen38-q4km-arcb70-llamacpp-tp1.
- Pulls the exact container image by sha256 digest — the bytes that were validated, not a floating tag.
- Fetches any required engine assets from this registry and verifies each against its recorded sha256; the audited launch script verifies them again inside the container before use.
- Downloads the pinned model revision into your Hugging Face cache on first run (reused afterwards).
- Serves an OpenAI-compatible API on
localhost:8010— point any client at it.
