Averaged over the benchmarks both models sat, grok-4-1-fast-reasoning returns 304.5 points of pass rate per dollar of blended price against 63.2 — 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. No published following instructions or tool use score for one of these models, so those lenses are omitted. And a benchmark is not your workload — it narrows the shortlist, it does not pick for you.
Which to pick
- Cheaper input: command-r
- Cheaper output: grok-4-1-fast-reasoning
- Larger context: grok-4-1-fast-reasoning
- Better at coding: grok-4-1-fast-reasoning (4.8% vs 82.2% on LiveCodeBench)
- Better at hard reasoning: grok-4-1-fast-reasoning (28.4% vs 85.3% 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.
