This model is quite useful as well, but from what I understand, it's limited to roughly 25 interactions per month.

Another practical approach is to create an "auditor" agent that can independently review and challenge responses. If setting up an agent is too complex, an alternative is to open a separate chat, paste the original answer there, and ask another model such as Opus or GPT to review it.

That's actually how I discovered that, within the same conversation, a form of determinism can emerge: the AI tends to be influenced by its previous responses and may unconsciously try to justify or defend them instead of reassessing the issue from a completely fresh perspective. Using a second model or a separate chat often helps provide a more independent review and can reveal errors, omissions, or assumptions that might otherwise go unnoticed.
