Anthropic released Claude Opus 4.1. This isn’t just another update, but a substantial improvement in coding capabilities and agent functionality. What’s especially pleasing — the new version is integrated not only into the classic Claude interface, but also into the Claude Code tool. As well as available through API, Amazon Bedrock and Google Cloud Vertex AI.
