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.

Faced with the news it was set to be replaced, the AI tool threatened to blackmail the engineer in charge by revealing an extramarital affair.

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.

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

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

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.

With top scores in real-world coding benchmarks, Anthropic's new models, Claude Opus 4 and Sonnet 4 are here; here's what they can do.
