transmission 11 · the operator’s ledger
Not Cognition’s history — the operator’s. This is the local accounting of one user’s Devin usage: every assistant turn, every model, every project, pulled straight from the sessions database on this machine.
| 6.37B | 61,537 | 661 | 9 |
| tokens burned | assistant turns | sessions | days on record |
Nine days of local Devin CLI/Desktop telemetry — every assistant turn in every session, deduplicated by message key the same way otter-stats does it. The window is 2026-10-07 to 2026-10-15; the peak was 2026-10-10 at 1.43B tokens in a single day.

Honest footnote: cache-read dominates the ledger — it is context re-read from the provider’s cache, not fresh reasoning. Of swe-2-high’s 4.57B tokens, 4.34B are cache reads. Output tokens — the part that is actually authored — total 42.4M across all models.

The operator ran 661 sessions in nine days and let the agents keep the receipts. Most of them ran in accept-edits mode — trust, but verify the diff.
