glm53-flash-exl3-tr3-4bpw-dflash2-rtxpro6000-vllm-tp2
glm53-flash-exl3-tr3-4bpw-dflash2-rtxpro6000-vllm-tp2Publisher-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.
- 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:8000— point any client at it.
