vLLM adds Kimi-K3 MegaMoE support with fp8 and fp4 quantization
August 15, 2026
vLLM has merged support for the Kimi-K3 MegaMoE model, enabling optimized inference via fp8_fp4_mega_moe kernels. This adds low-precision quantization support for the Kimi-K3 architecture within the vLLM runtime.
HOW THIS AFFECTS YOU
●
builderYou can now deploy Kimi-K3 MegaMoE with significantly lower memory overhead using fp4/fp8 quantization.
●
researcherThis provides a production-ready environment to test MegaMoE scaling and quantization sensitivity.
