For Claude to learn from experience, it has to decide what’s worth remembering before it knows what’s next. Here’s how “dreaming” helps it organize memory and correct mistakes.
As our merges per day grew more than tenfold, source control became our biggest development bottleneck. Here, we share how we migrated to an in-house version control system in five months.
Harness design is key to performance at the frontier of agentic coding. Here's how we pushed Claude further in frontend design and long-running autonomous software engineering.
What we learned from three iterations of a performance engineering take-home that Claude keeps beating.
Works to understand the risks of AI models and develop ways to ensure future ones remain helpful, honest, and harmless.
Studies and monitors the impact of AI systems on individuals, firms, and economies.
Stress-tests AI systems to understand the full extent of their current capabilities and anticipate what comes next.
Studies how large language models work internally as a foundation for AI safety.
Studies how AI affects people, both individually and collectively.
Explores how AI can increase the pace of scientific progress through both research and collaborations.
Builds the infrastructure and systems that make Claude reliable and trustworthy.
