The current benchmark capture reports aggregate intelligence indices of 64.6 for Claude Fable 5.2 (Max, Default Fallback) and 54.6 for GPT-6.1 Sol (Max).

Sol’s unit rates are one-quarter of Fable’s

Sol lists $2 input and $10 output per million tokens. Fable lists $8 and $40, and has the higher aggregate index. Fable starts sooner and produces subsequent tokens faster in the captured measurements.

What to measure on your workload

Test tasks at a realistic output length. The response time difference may be meaningful in a live interface, while Sol’s lower per-token rates can matter more when many routine requests are acceptable on the first try.
