What is Claude Opus 5?

Claude Opus 5 is Anthropic's current Opus-tier model, positioned as an everyday, general-purpose model for coding, agentic work, and enterprise knowledge tasks, released July 24, 2026.

It's designed to approach the intelligence of Anthropic's top-tier Claude Fable 5 model on many tasks while costing about half as much, making it the more cost-efficient default for most day-to-day use unless a task specifically calls for Fable 5's extra capability.

It's available as claude-opus-5 through the Claude API, and also through Amazon Bedrock, Google Cloud, and Microsoft Foundry, alongside continued availability of the prior Opus 4.8 model.
