05 / EVALUATIONS
How to read the results
“
A public benchmark provides guidance, but does not replace an evaluation with your data, tools, budget, and error tolerance.
| Benchmark | Result | Metric | Source |
|---|---|---|---|
| SWE-Bench Pro | 54,2 % | Resolved | View source ↗ |
| Terminal-Bench 2.1 | 70,7 % | Accuracy | View source ↗ |
Inferama only highlights a “best result” when the metric, test set, configuration, and date allow for an equivalent comparison. The supplier's figures are presented as claims from its own source.

Gemini 3.1 Pro with tools: how to test it before trusting it with a workflow
Google describes Gemini 3.1 Pro as a model for complex tasks, but that description does not prove that a specific integration can reliably complete a multi-step workflow. We propose a reversible evaluation protocol and explain what the available sources can—and cannot—establish about access, pricing, safety, and performance.

There are no results from a controlled comparison here that would support declaring a winner. What we can offer is a reproducible protocol for measuring patch quality, regressions, cost, and time under shared conditions—and for deciding what evidence a team needs before choosing.
