Claude Opus 5 now available on AI Gateway
By Steven Van ·
Vercel's AI Gateway adds Claude Opus 5 across four providers, priced at $5/$25 per million tokens with no gateway markup.
Anthropic's Claude Opus 5 is now available on Vercel's AI Gateway, alongside Anthropic, Bedrock, Google Vertex AI, and Claude Platform on AWS. It improves on Claude Opus 4.8 for long-horizon agentic coding: multi-file features, larger refactors, and end-to-end work, finishing full implementations rather than leaving stubs or placeholders.
- Reasoning is on by default, set via a top-level reasoning option from minimal up to xhigh, or off entirely; low and medium effort already produce quality output at lower token and latency cost.
- Vision is stronger on charts, documents, diagrams, and UI replication, and the model can use tools to crop and verify visual work.
- It coordinates teams of subagents well, suiting multi-agent workflows.
- Like Claude Fable 5, it ships with elevated cybersecurity safeguards, so benign security work can occasionally get blocked by a safety classifier; AI Gateway's models fallback array under providerOptions.gateway can list backup models to try when that happens.
Pricing is $5 per million input tokens and $25 per million output tokens, mirrored from the provider with no markup. The model is compatible with Zero Data Retention, and fast mode is available separately via speed: 'fast' in the Anthropic provider options. Full details are on the announcement page.
