Anthropic just unveiled its Claude Opus 4 and Claude Sonnet 4 models. Just like all other AI companies, Anthropic is working on AI agents that can work for you. This goes far beyond simply using a chatbot.

Claude Sonnet 4 boosts coding, reasoning, and agent capabilities with enhanced memory, speed, and steerability across major dev platforms.

Anthropic's Claude Opus 4 outperforms OpenAI's GPT-4.1 with unprecedented seven-hour autonomous coding sessions and record-breaking 72.5% SWE-bench score, transforming AI from quick-response tool to day-long collaborator.

The company said it was taking the measures as a precaution and that the team had not yet determined if its newst model has crossed the benchmark that would require that protection.

Anthropic's newest editon of its flagship AI product will address significant limitations in current large language models.

Anthropic has announced the release of its latest AI models, Claude Opus 4 and Claude Sonnet 4, which aim to support a wider range of professional and academic tasks beyond code generation. According to Anthropic, Claude Opus 4 is optimized for extended, focused sessions that involve complex reasoning, context retention and tool use.

After a long wait, Anthropic has unveiled the next generation of its AI. Claude Opus 4 and Sonnet 4 are designed to excel at complex programming tasks.

Claude Opus 4 and Claude Sonnet 4, Anthropic's latest generation of frontier AI models, were announced Thursday.
