OpenAI 的模型命名越来越绕了，看看 E 教授的实测对比，帮你搞清 GPT-5.6 各版本谁最强。
Ethan Mollick 指出 GPT-5.6 Pro（仅聊天机器人可用）是目前最智能的模型。GPT-5.6 Ultra（Codex 中的最佳模型）在困难任务上表现较弱。对于真正难题，排名为：GPT-5.6 Sol Pro > Fable 5 Ultracode > GPT-5.6 Sol Ultra。模型命名令用户困惑。

let us know what you think of pro-ultra-superhard Ethan Mollick @emollick Agreed: GPT-5.6 Pro (which is only available via the chatbot) is the smartest model out there. GPT-5.6 Ultra (the best model in Codex) is not near as powerful on hard tasks. For really hard problems: GPT-5.6 Sol Pro>Fable 5 Ultracode > GPT-5.6 Sol Ultra.
