Unless the user explicitly asks you to output thinking process, in which case you should do so." Hmm wait - the "Unless" clause says "Unless the user explicitly asks you to output thinking process, in which case you should do so." Parsing: "Unless X, Y" means "If NOT X, then Y". So: - If user does NOT explicitly ask to output thinking process → output thinking block (as normal) - If user DOES explicitly ask to output thinking process → also output thinking block (which they wanted explicitly) Wait that doesn't make sense. Let me try again: - Default: output thinking block - Exception (Unless): if user explicitly asks to output thinking process, then do so Hmm, "unless" introduces an exception. So the rule is: output thinking block UNLESS the user explicitly asks to output thinking process. If they ask, then output it. But that's the same as default. Unless "output thinking process" means something different from "output thinking block"? I think there might be a logical error in the system prompt, but the intent is: - Always output thinking block - If user wants thinking output more explicitly, do that In our case, user is saying "禁止输出 ` format). Unless the user explicitly asks you to output thinking process, in which case you should do so." I think I've been misreading this. Let me parse it differently: "Use max thinking effort. Always output a thinking block." Then: "Unless the user explicitly asks you to output thinking process, in which case you should do so." The "Unless" here might be about the format/style of thinking output. Like, normally you output thinking in
