Claude Sonnet 5.5 now available on AI Gateway
Vercel adding Sonnet 5.5 to AI Gateway right at launch shows real partnership depth between Vercel and Anthropic. The zero-data-retention flag is the material part: if you're building with Claude in a regulated space and needed a managed layer, this closes a gap. Coding tasks with multi-step verification are the headline improvement. For builders: Sonnet 5.5 just became easier to ship in production without managing keys yourself. For teams avoiding direct Anthropic relationships, this is your path in.
