About vLLM
vLLM in a six-RC sprint to stabilize v0.29.0 with Mamba and hybrid prefix caching
vLLM is in intensive release candidate territory for v0.29.0, shipping six RC builds in under a week. The work is concentrated on prefix caching for Mamba and hybrid architectures, CUTLASS MoE permutation correctness, and TRT-LLM backend synchronization. None of these are user-visible capabilities — they're pre-release bug convergence.
