Introducing Claude Opus 4.5

By Anthropic

Summary

## Key takeaways - **Best at coding and agents**: Claude Opus 4.5 is our best model yet. It's the best in the world at coding, agentic tasks and everyday work like spreadsheets. [00:03], [00:05] - **Higher trust, fewer interventions**: I trust this model more. My time between interventions keeps getting longer, and I keep seeing colleagues say it solved a bug that Sonnet never could have found. [00:12], [00:13] - **Thinks before acting**: The model is also more efficient because it knows when to think before acting, so that it makes the right change. [00:19] - **Beat humans on engineering task**: We’ve got this take home. It's a two hour intensive engineering task. And in that time, the model scored higher than any human ever has. [00:25], [00:28] - **Superior vision and computer use**: It’s also much better at front end. It's way better at vision, and that makes it a lot better at using computers. [00:33], [00:35] - **Available on all major clouds**: Opus 4.5 is available today. For the first time, it's on every major cloud platform. [00:38], [00:40]
