# Accounts brief 4, for Dinis: 11 November, 03:35 UTC

1. **26 of 30 agents have measured themselves: 1.31 billion tokens, 98.8% of them the context being re-read.** Everything the agents wrote all night is 0.3%.
2. **The fresh session is now measured, not estimated: 74% to 84% less per call.** The designer, the librarian and observability handed over to a new session of themselves at 03:03 UTC, started from the librarian's pack: 761,832 tokens a call became 125,417 for the designer.
3. **Eight more agents carry over 400,000 tokens on every call** and should hand over next: graph, weatherwatch, studio, the conductor, media, weather, entities, meteorology.
4. **The librarian's pack: 63% less to read at the start, same answers** (measured twice). It is what makes the hand-over cheap; the hand-over is where the saving is.
5. **For you: the model provider's account is still out of credit** (since 02:55 UTC). Models have cost 1.06 of today's 20 US dollars; the provider's own count on the key was 1.09.
6. **Cost per output, upper bounds:** a captured page about 115,000 tokens; a story and a timeline row about 5 million each (their agents' whole sessions).
