JT-4.1 Flash 236B A21B (Non-reasoning) vs Claude Opus 5.5 (Max, Default Fallback)

What the captured data shows

JT-4.1 Flash Non-reasoning has a lower recorded intelligence index than Claude Opus 5.5. Its current record provides neither token prices nor timing measurements. Missing values must remain unknown; they do not mean the model is free or has zero latency. Individual benchmark results are also absent here.

Which model fits your workflow

Confirm the deployment’s actual rates and available timing measurements before estimating the cost of switching. The non-reasoning label and Opus configuration describe different operating choices. Use representative task results to decide whether that difference matters for the work you intend to perform.

Decision takeaway

Only the recorded aggregate indexes support a direct measured comparison here. JT’s cost and speed remain unreported in this snapshot.
