What is 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.

What is Snorkel AI?

Snorkel AI turns its coding benchmark on Fable 5.2 and finds the terminal failures mostly gone.

Snorkel AI's feed is research and benchmark posts about how agents are evaluated. The newest compares Fable 5.2 with Fable 5.1 on 26 frontier coding tasks: pass@1 rises from 53% to 71%, and the mid-run terminal failures seen in 5.1 nearly disappear. It follows Terminal-Bench 4.1, which hardened verifiers against reward hacking, and a run of early-November posts on reward peeking and energy efficiency.

◆ Current state

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.

◆ Where it's heading

What these patches describe is the real cost of supporting frontier architectures early: each new model family brings its own interaction with speculative decoding, sliding-window KV allocation, quantised MoE kernels and disaggregated serving, and the failures surface as wrong output rather than crashes. The recurring FlashInfer dependency issues point to a kernel layer moving as fast as the models above it. Because only .post tags are captured, none of the actual feature releases appear, so this feed shows the stabilisation work and none of the shipping.

◆ Prediction

Expect further .post patches tracking whichever model family lands next; a read on SGLang's feature direction isn't possible until the minor releases themselves appear in this feed.

5.0

Snorkel AI turns its coding benchmark on Fable 5.2 and finds the terminal failures mostly gone.

◆ Current state

Snorkel AI's feed is research and benchmark posts about how agents are evaluated. The newest compares Fable 5.2 with Fable 5.1 on 26 frontier coding tasks: pass@1 rises from 53% to 71%, and the mid-run terminal failures seen in 5.1 nearly disappear. It follows Terminal-Bench 4.1, which hardened verifiers against reward hacking, and a run of early-November posts on reward peeking and energy efficiency.

◆ Where it's heading

Snorkel is positioning itself as the outside scorer of frontier models: it funds open benchmarks, publishes the methods that keep them honest, and now runs head-to-head model comparisons on its own task sets. The posts sell its evaluation data business by example rather than through product releases.

◆ Prediction

Expect more model-versus-model results on Snorkel task sets as new frontier releases land. The entries show no product or pricing change, so whether this becomes a public leaderboard is unclear.
