Introducing Claude Opus 5

Simon Willison's Weblog 2 months ago 53 ● 17 sources

Anthropic released Claude Opus 5, a new large language model that leads the Artificial Analysis leaderboard and matches Claude Opus 4.8 in price. The model demonstrated the ability to independently write a computer vision pipeline to analyze machine drawings and reconstruct 3D models when direct image viewing was unavailable. Opus 5 improved at finding cybersecurity vulnerabilities through general capability gains rather than explicit training, while Anthropic deliberately avoided training it on exploitation techniques.

Meta is making its AI chatbot more like an assistant

The Verge 2 months ago 16

Meta is upgrading its AI chatbot with new features including calendar integration for event planning, daily briefings, and steerable in-depth research to compete with ChatGPT and Claude. The update uses Meta's newly released Llama 3.1 model, which expands the chatbot beyond basic question-answering and image generation. These productivity features position Meta AI as a personal assistant rather than just a conversational tool, aligning with CEO Mark Zuckerberg's vision of personal superintelligence.
