Anthropic has launched its next-generation AI models, Claude Opus 4 and Claude Sonnet 4, touting Opus 4 as a leading coding model.
Anthropic today announced the next generation of Claude models: Claude Opus 4 and Claude Sonnet 4. Anthropic claims that its flagship Claude Opus 4 is the world’s best coding model and excels in agentic workflows and complex, long-running tasks. The Claude Sonnet 4 comes with improved coding and reasoning performance compared to the existing Claude Sonnet 3.7 model.
As you can notice in the table below, Claude Sonnet 4 scored a state-of-the-art 72.7% on SWE-bench Verified, the popular benchmark for agentic coding. Because of its powerful coding capabilities, Microsoft’s GitHub today announced that Sonnet 4 will be the model powering the new coding agent in GitHub Copilot.
