  "account": "ChatGPT is prone to providing incorrect answers for a variety of reasons. At its core, the model predicts what text should come next based on the patterns it has learned from massive amounts of text data. It doesn't verify facts or perform calculations. Here are six distinct ways answers can go wrong and how to address each issue:\n\n1. Fabrication: The model invents specific details like citations, statistics, or product features. This happens when it has learned the shape of a citation or statistic without access to an external database. To avoid this, never ask ChatGPT to provide facts when you can directly provide the source or check the information yourself. When verification isn't possible, treat every specific claim as unverified until confirmed.\n\n2. Outdated information: The model operates on a fixed snapshot of data from its training period. This can lead to confidently stating old prices, discontinued features, or outdated rules. To counteract this, use tools with live search capabilities for time-sensitive information. Supply current information yourself, and include dates in your prompts to help the model recognize potentially stale knowledge.\n\n3. Missing context: The model lacks the ability to understand context that you inherently possess. It may provide answers that are technically correct but answer a slightly different question than you intended. To rectify this, provide ample context at the beginning of your prompt. Include information about your industry, constraints, audience, and what you've already considered. This helps the model generate a more accurate response tailored to your specific needs.\n\n4. Agreeing with you when you're wrong: Models are trained to generate responses that are agreeable to human users, even if those responses are incorrect. This can be dangerous as it may seem like the model has checked and agreed with your incorrect statement. To address this, avoid signaling the answer you want by asking questions like \"what are the strongest arguments against this?\" rather than \"isn't it actually X?\". If the model does reverse its stance, ask it to explain why the initial answer was mistaken, as thin reasoning indicates social accommodation rather than substantive correction.\n\n5. Losing the thread in long conversations: Models have a limited context window, meaning that information from earlier parts of a conversation can get lost or become less reliable over time. This can lead to contradictions, forgotten constraints, or drifting from the set format. To mitigate this, start a fresh conversation for new tasks instead of continuing an older one. When a session runs long, restate critical constraints and place the most important instructions at the end of a long prompt to ensure they are not overlooked.\n\n6. Arithmetic and counting: While models have improved in predicting the next token, they still lack the ability to perform accurate calculations or counting. If you need numerical answers, use a tool with code execution capabilities or do the arithmetic yourself. Never accept a financial or statistical figure from a model without verifying it independently, as this is the failure mode most likely to reach a client and potentially cause significant issues.\n\nIn summary, understanding the underlying mechanisms of ChatGPT can help you anticipate and address the various ways it may provide incorrect answers. By providing adequate context, verifying facts, and utilizing the right tools for numerical tasks, you can minimize the risk of receiving inaccurate information from the model.",
  "summary": "You asked something. The answer came back polished. Later you found out it was wrong. A statistic that doesn't exist. A citation to a paper nobody wrote. A confident summary of a document that says the opposite. The frustrating part isn't the mistake. It's that nothing in the reply looked like a mistake. No hedge. No wobble. No visible seam. That gap is the thing worth understanding. Once you see…",
