glm53-flash-exl3-tr3-4bpw-dflash2-rtxpro6000-vllm-tp2

glm53-flash-exl3-tr3-4bpw-dflash2-rtxpro6000-vllm-tp2

Publisher-qualified language-only GLM-5.3 Flash TR3 EXL3 4bpw recipe for two RTX PRO 6000 Blackwell GPUs. Uses TP2/EP2/DCP2, B12X sparse MLA, NVFP4 MLA KV, external DFlash2 with seven draft tokens, and full-and-piecewise CUDA graphs. Speed evidence uses the model card's sustained streaming methodology; C2/C4 rows are intentionally omitted because the card marks them capacity-limited rather than throughput claims.

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 glm53-flash-exl3-tr3-4bpw-dflash2-rtxpro6000-vllm-tp2.

  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:8000 — point any client at it.
