LLMs also don't have the primary advantage humans get from job separation, diverse perspectives. A council of Opuses are all exploring the exact same weights with the exact same hardware, unlike multiple humans with unique brains and memories. Even with different ones, Codex 5.3 is far more similar to Opus than any two humans are to each other. Telling an Opus agent to focus on security puts it in a different part of the weights, but it's the same graph-- it's not really more of an expert than a general Opus agent with a rule to maintain secure practices.
