# Claude Opus 4.1 is now supported in Vercel AI Gateway

By Steven Van · 2025-08-05

No separate Anthropic account is needed, and existing AI SDK v5 apps can switch to the model with a single string update.

Anthropic's new Claude Opus 4.1 model is now available through [Vercel](<https://creatorstoolbox.com/tools/vercel>)'s [AI Gateway](<https://vercel.com/ai-gateway>), with no separate Anthropic account required. Anthropic says the release improves agentic task execution, real-world coding, and reasoning over the previous Opus 4 model.

Developers on the AI SDK v5 can switch to it with a single model string update, to **anthropic/claude-4.1-opus**. AI Gateway adds built-in observability, Bring Your Own Key support, and intelligent provider routing with automatic retries, drawing on multiple providers including Anthropic and Bedrock to keep uptime above the provider average.
