Anthropic reports how Claude organizes agent memory

Anthropic's Nov. 6 engineering post says Claude can write memory notes during a session and later reorganize them by checking transcripts, a step it calls dreaming. In one Pokemon comparison, Sonnet 3.7 wrote 413 memory files and earned one badge, while Fable 5 wrote nine files and earned four. On about 350,000 Stainless files, scores on 25 questions rose from 13 percent to 48 percent as dreaming scaled from two sessions to 128, and search plus a wiki reached 61 percent against 53 percent for search alone.
