Paste Period A and Period B trace JSON above to compare model-level cost deltas.
Why this tool
The bill jumped 40% this week and nobody knows why. Compare puts last week and this week side by side, broken down per model, with a per-model delta and percent change so you can point to the model line that moved before the postmortem.
How it works
- 1
Export the two trace windows you want to diff as JSON or NDJSON.
- 2
Paste period A on the left and period B on the right, then click Compare.
- 3
Read the per-model delta table; download the JSON for the spike RCA.
