Run `nvidia/GLM-5.3-Flash-NVFP4` on sglang.
Take the official FP8 cookbook launch command, use the NVFP4 checkpoint, run it through this wrapper. That's it.
Launch:
```bash
python glm53_patch.py \
--model-path nvidia/GLM-5.3-Flash-NVFP4 \
--tp-size 4 \
--ep-size 4 \
--quantization modelopt_fp4 \
--moe-runner-backend flashinfer_cutlass \
--trust-remote-code
```
All normal `sglang.launch_server` args are passed through after the script name.
## What the wrapper fixes
1. **Shape mismatch on load** (`[8192, 256]` vs `[8192, 512]`) — the checkpoint's exclude list uses `model.language_model.*` / `model.visual*` prefixes, but sglang renames them only *after* model construction, so excluded layers were built FP4-packed. The patch pre-maps the exclude list and forces `UnquantizedLinearMethod` for the vision tower.
2. **GLM-5 fused modules missing from `packed_modules_mapping`** — `fused_qkvbfg_a_proj`, `qkv_proj`, `qkv_conv1d`, etc. are injected.
3. **Version drift** — `_use_nv…
