One environment variable swaps Gemma 4 to its 2.05x-faster QAT weights on a SageMaker L4

Gemma 4 E2B's 4-bit QAT checkpoint decodes 2.05x faster than bf16 on one SageMaker L4, according to a dev.to benchmark. The swap also frees 18% of GPU memory for a 20% larger KV cache, though it runs only through the vLLM container because JumpStart lists no QAT build.
