Netlify adds Sonnet 5.5 to AI Gateway

Netlify now makes Claude Sonnet 5.5 available through AI Gateway and Agent Runners, letting Functions call `claude-sonnet-5-5` with the Anthropic SDK while Netlify handles access and infrastructure. Sonnet 5.5 launched today as a faster, more efficient coding model. [Anthropic](https://www.anthropic.com/claude-sonnet-5-5)

// ANALYSIS

Netlify is turning model access into deployment plumbing, which is valuable for teams that want to ship AI features without operating provider credentials or routing infrastructure.

–Sonnet 5.5 claims 30%+ faster generation and up to 30% lower cost per task than Sonnet 5, strengthening its case for iterative coding workloads. [Anthropic](https://www.anthropic.com/claude-sonnet-5-5)
–AI Gateway centralizes model access, authentication, rate limiting, and usage management inside Netlify’s existing platform. [Netlify Docs](https://docs.netlify.com/build/ai-gateway/overview/)
–Agent Runners extend the same model availability into dashboard-driven coding workflows that produce reviewable Deploy Previews. [Netlify Docs](https://docs.netlify.com/build/build-with-ai/agent-runners/overview/)
–The main open question is economics: Netlify credits and model-selection controls will determine whether convenience outweighs using Anthropic directly.
