Ideas on memory worth reading.
What actually happens when you try to give AI agents long-term memory. The wins, the unsolved problems, and the parts nobody warns you about.
Memory for AI That Operates Under Audit
Whisper hallucinated in clinical transcripts. Memory layers are the next surface. Feature coverage across OSS layers, a compliance-control mapping (HIPAA, SOC 2, GDPR, EU AI Act), and what we still owe.

Context windows keep getting bigger. 128K, 1M, 10M tokens. But bigger context is not memory. Three research papers, real cost math, and benchmark data explain why.
