lfm25-26b-bf16-rtx2000ada-sglang-tp1

Capacity-limited LFM2.5-2.6B BF16 recipe on one RTX 2000 Ada. Exact 128K C1 and C2 passed correctness, timing, cache reporting, and decode CUDA-graph execution; C4 is capacity-rejected because 524,288 tokens exceed the measured 286,188-token pool.

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 lfm25-26b-bf16-rtx2000ada-sglang-tp1.

  1. Pulls the exact container image by sha256 digest — the bytes that were validated, not a floating tag.
  2. 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.
  3. Downloads the pinned model revision into your Hugging Face cache on first run (reused afterwards).
  4. Serves an OpenAI-compatible API on localhost:30000 — point any client at it.
