Anthropic unveiled its latest generation of “frontier,” or cutting-edge, AI models, Claude Opus 4 and Claude Sonnet 4, during its first conference for developers on Thursday in San Francisco. The AI startup, valued at over $61 billion, said in a blog post that the new, highly anticipated Opus model is “the world’s best coding model,” and “delivers sustained performance on long-running tasks that require focused effort and thousands of steps.” AI agents powered by the new models can analyze thousands of data sources and perform complex actions.
The new release underscores the fierce competition among companies racing to build the world’s most advanced AI models—especially in areas like software coding—and implement new techniques for speed and efficiency, as Google did this week with its experimental research model demo called Gemini Diffusion. On a benchmark comparing how well different large language models perform on software engineering tasks, Anthropic’s two models beat OpenAI’s latest models, while Google’s best model lagged behind.
