About SGLang
Only patch tags reach this feed, and every one of them is frontier-model firefighting
SGLang is a serving engine for large language models, and the three entries captured here are all .post patch releases rather than feature versions. Their content is narrow and specific: GLM 5.2 failing under prefill/decode disaggregation and context parallelism, DeepSeek V4 emitting garbled text during single-token decode on B200/B300 hardware, NaN outputs from FlashInfer TRT-LLM FP4 MoE kernels on long inputs, and a FlashInfer version bump to fix its JIT cubin downloader.
