SGLang Team Launches RadixArk With $100M Seed Round

拿下1亿美元种子轮！SGLang团队创立RadixArk，打造下一代开放AI基础设施

RadixArk announced a $100 million seed round on May 5 at a $400 million post-money valuation, while its SGLang inference project has 27K+ GitHub stars and deployments across 400K+ GPUs.

Why it matters: HKR-H/K/R all pass: the round size, valuation, and deployment numbers are concrete, and SGLang is a known inference stack. It is still a startup funding and infra-roadmap story, not a major model release, so it stays in the 78–84 featured band.
