Our autoresearch system at @Recursive_SI discovered that some FlashInfer kernels (underpinning @vLLM_project & @SGL_project) use a hard-coded value of -50000 as masked-attention sentinel despite that QK values can be smaller and thus cause instabilities. Small but great win. 19.8K views · 200 likes · 12 reposts · 6 replies 28 Aug 2026 · Open on X →
A fun small win for automated research: We found and helped fix some edge cases that could affect inference performance in vLLM and SGLang. In our last blog post, we described a reward hacking judge we developed for performance optimization tasks.
