vllm 0.7.1

v0.7.1

on Python PyPI

Highlights

This release features MLA optimization for Deepseek family of models. Compared to v0.7.0 released this Monday, we offer ~3x the generation throughput, ~10x the memory capacity for tokens, and horizontal context scalability with pipeline parallelism

• MLA Kernel (#12601, #12642,#12528).
• FP8 Kernels (#11589, #11868, #12587)

V1

For the V1 architecture, we

• Added a new design document for zero overhead prefix caching here (#12598)
• Add metrics and enhance logging for V1 engine (#12569, #12561, #12416, #12516, #12530, #12478)

Hardwares

• Neuron: NKI-based flash-attention kernel with paged KV cache (#11277)
• AMD: llama 3.2 support upstreaming (#12421)

Others

• Support override generation config in engine arguments (#12409)
• Support reasoning content in API for deepseek R1 (#12473)
