The study defines agent memory as persistent, experience-based knowledge and introduces 'dreaming' to correct errors, with benchmarks showing significant performance gains for newer Claude models.
Anthropic researchers argue AI must return model distributions, not single fits, to provide scientific insight
Jakob Macke, Daniel Gedon, and Stefan Wahl argue that AI tools for science should return the full distribution of compatible models rather than a single optimal fit to reveal what data actually constrains.
Anthropic analysis of 207,049 sessions finds Claude usage tracks AI capability, with data analysis and writing dominating scientific research
Analysis of 207,049 sessions reveals that scientists use Claude most for tasks where AI performs well, such as data analysis and writing, while underutilizing it for physical data collection and ideation.
Anthropic researchers use Claude to determine the first 3D structure of a prokaryotic vault particle
The team used Claude to optimize isolation and processing, reducing a three-day purification to 90 minutes and solving the structure in 34 hours.
