- What happened
- PAST-Bench benchmark tests whether personal AI agents actually improve over time by reusing retained experience across sessions.
- Why it matters
- Matters for engineers building persistent AI assistants that learn from user interactions and maintain memory across conversations.
- Watch out
- Improvement is real but uneven across capabilities and models. Agents showing same headline gains differ markedly in whether gains follow intended save-retrieve-update pathways.
