| `SGLANG_INT4_WEIGHT` | Enable INT4 weight quantization | `false` |
| `SGLANG_PER_TOKEN_GROUP_QUANT_8BIT_V2` | Apply per token group quantization kernel with fused silu and mul and masked m | `false` |
| `SGLANG_FORCE_FP8_MARLIN` | Force using FP8 MARLIN kernels even if other FP8 kernels are available | `false` |
| `SGLANG_FLASHINFER_FP4_GEMM_BACKEND` (deprecated) | Select backend for `mm_fp4` on Blackwell GPUs. **DEPRECATED**: Please use `--fp4-gemm-backend` instead. | `` |
| `SGLANG_NVFP4_CKPT_FP8_GEMM_IN_ATTN` | Quantize q_b_proj from BF16 to FP8 when launching DeepSeek NVFP4 checkpoint | `false` |
| `SGLANG_MOE_NVFP4_DISPATCH` | Use nvfp4 for moe dispatch (on flashinfer_cutlass or flashinfer_cutedsl moe runner backend) | `"false"` |
| `SGLANG_NVFP4_CKPT_FP8_NEXTN_MOE` | Quantize moe of nextn layer from BF16 to FP8 when launching DeepSeek NVFP4 checkpoint | `false` |
| `SGLANG_ENABLE_FLASHINFER_FP8_GEMM` (deprecated) | Use flashinfer kernels when running blockwise fp8 GEMM on Blackwell GPUs. **DEPRECATED**: Please use `--fp8-gemm-backend=flashinfer_trtllm` (SM100/SM103) or `--fp8-gemm-backend=flashinfer_cutlass` (SM120/SM121 and newer) instead. | `false` |

| `SGLANG_QUANT_ALLOW_DOWNCASTING` | Allow weight dtype downcasting during loading (e.g., fp32 → fp16). By default, SGLang rejects this kind of downcasting when using quantization. | `false` |
| `SGLANG_FP8_IGNORED_LAYERS` | A comma-separated list of layer names to ignore during FP8 quantization. For example: `model.layers.0,model.layers.1.,qkv_proj`. | `""` |
