Anthropic has introduced Claude Opus 4.5, a hybrid reasoning model for coding, agents, and computer use. The company said this new version of the Claude Opus model offers better vision, reasoning, and mathematics than predecessors.
Claude Opus 4.5 is meaningfully better at everyday tasks such as deep research and working with slides and spreadsheets, Anthropic said.
Claude Opus 4.5 was introduced November 24. It is available now in Anthropic’s consumer applications, its API, and on all three major cloud platforms including Amazon Web Services, Google Cloud Platform, and Microsoft Azure. Developers can access the model by using claude-opus-4-5-20251101 via the Claude API.
