## Summary

SGLang says RadixArk is working with Google on a fully pipelined megakernel for Muse Spark Open, optimized for long-context agentic workloads. SGLang says performance on TPUv7 is now very competitive with popular GPU options. More models on SGLang-TorchTPU are planned.

Congrats to the Google TPU team, and thanks @SemiAnalysis_ for a clear look at where TPU stands today and the potential it holds for production agentic workloads.

We’re excited to see @radixark work with Google to build a fully pipelined megakernel for Muse Spark Open, with deep optimizations for long-context agentic workloads. On TPUv7, the performance is now very competitive with popular GPU options.

More models on SGLang-TorchTPU are in the works, and TPU will only get stronger for anyone serving AI at scale 🧡
