CodePanel's benchmark has not run GPT-5.5 Pro as a pull-request reviewer yet, so this page has no recall, false-alarm or measured-cost figures for it. The methodology explains how ranked models are scored.
No GPT Pro model is ranked yet. Of OpenAI's ranked models, GPT-5.6 Sol is the closest in list price; it caught 72% [59%–85%] of the known bugs at rank 1 of 17, with a measured review cost of $0.1127. At list price, a typical review call (26.2K tokens in and 2.4K out) costs $1.2213 on GPT-5.5 Pro and $0.1532 on GPT-5.6 Sol, so this model's call is 8.0× the cost of that one's.
