What happened: SGLang-Neuron v0.1.0 open-sourced, a PyTorch plugin serving LLMs and diffusion models on AWS Trainium chips with optimized kernels.
Why it matters: Engineers deploying large language models at scale who want to run inference on AWS Trainium hardware with cost-efficient serving.
Watch out: Still in public preview. Megakernel support limited to specific models like GPT-OSS-120B, GLM-5.2, and Kimi-K3. Requires AWS Deep Learning Container.

Each one covers how the technique works, when it earns its cost, and where it breaks.

One pattern, one tradeoff, one production failure story. A short weekly briefing for people building agentic systems.
