Baseten: Claude Code vibe-built VibeQwen beats vLLM by up to 90%
Baseten used Claude Code (Fable 5) plus MetaInfer skills to vibe-build VibeQwen—a Qwen-3.6-35B-A3B NVFP4 engine on one B200 that beat tuned vLLM 0.25.1 by up to 90% single-stream decode (1,792 vs 943 TPS) and cut TTFT 28→12ms; a follow-on SAM 3.1 server gained ~50% throughput. Experimental only—not serving production yet.
