Anthropic’s guide for Claude tells users to be “more specifically,” spelling out what, how, and for whom the output should be, because the latest Claude models “no longer guess” and act faithfully to the exact wording. OpenAI’s guide for ChatGPT, by contrast, advises users to state only the desired result and avoid overly detailed instructions, noting that the model “has started to make its own judgments” and that too much detail can hurt accuracy.\\\n\\\nBoth companies still stress three shared principles: clearly state the output in the first sentence, provide a single good example rather than a list of negatives, and identify the reader and purpose. The article offers a template that packs character count, format, and audience into the opening line, and shows how to adapt prompts for each model. It argues that recognizing these divergent styles can restore the quality of AI‑generated answers for marketers, side‑hustlers, and other users who felt recent outputs were “off.”","keyPoints":["Anthropic’s 2026 guide tells Claude users to write “more specifically” for higher accuracy.","OpenAI’s 2026 guide advises ChatGPT users to give only the goal and avoid excessive detail.","Both guides still require stating the output, providing one example, and specifying reader and purpose."],"whyItMatters":"Knowing the opposite prompt styles lets marketers and side‑hustlers extract more accurate results from Claude and ChatGPT, saving time and reducing trial‑and‑error.","category":{"slug":"marketing","name":"Marketing & Small Business","url":"https://digestai.news/category/marketing"},"entities":{"companies":["Anthropic","OpenAI"],"models":["Claude","ChatGPT"],"people":[]},"firstPublishedAt":"2026-09-20T05:58:00Z","updatedAt":"2026-09-20T05:58:00Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"note.com","title":"Just the results for ChatGPT, be specific for Claude.
