Claude Opus 4.5: a new standard in coding?

Anthropic has just released its latest model Claude Opus 4.5. They’re pitching it as the smartest and most efficient solution in the world, in fields like programming, handling autonomous agents, and computer work. According to the company, this model significantly improves everyday tasks, including deep research and spreadsheet analysis.

Opus 4.5 is now widely available. You can find it in Claude apps, via the API (under the identifier claude-opus-4-5-20251101), and through the three major cloud providers: Amazon Bedrock, Google Vertex AI and Microsoft Azure. Interestingly, Anthropic has decided to set the rates at 5 USD per million input tokens and 25 USD for output tokens. In their official statement, the company claims that such pricing aims to make Opus class model capabilities accessible to a broader audience of users and businesses. Anthropic’s partners echo this sentiment in their promotional materials, noting that previously, models of this class were often prohibitively expensive for many companies.
