Averaged over the benchmarks both models sat, jamba-mini-1.7 returns 82.3 points of pass rate per dollar of blended price against 7.6 — the ratio that decides whether the dearer model earns its rate.
Each figure is a pass rate: the share of that test set the model answered correctly, measured by a third party rather than self-reported by the lab. Rows are different tests of different difficulty, so compare a model against the other model, not one row against the next. And a benchmark is not your workload — it narrows the shortlist, it does not pick for you.
Which to pick
- Cheaper input: jamba-mini-1.7
- Cheaper output: jamba-mini-1.7
- Larger context: jamba-large-1.7
- Better at following instructions: jamba-large-1.7 (35.2% vs 31.4% on IFBench)
- Better at coding: jamba-large-1.7 (18.1% vs 6.1% on LiveCodeBench)

- Better at hard reasoning: jamba-large-1.7 (39.0% vs 32.2% on GPQA Diamond)
List price is not production cost. Output length, cache hit rate, retries and task quality move the real number more than the headline rate does — price your own prompt on the token ledger before deciding.
