Prompts that actually work

Fable 5.1 reports roughly double its predecessor on a science benchmark at twice the price of Opus 5. A benchmark that doubles and a workload that does not improve is a common outcome, and vendor numbers cannot tell you which you are looking at. These six prompts are for testing a model on your own work before you pay more for it.

K2 Horizon shipped with its training data published. Kimi, GLM and Qwen did not. A federal court has already held that acquiring training material through piracy is unlawful, and Sony and Warner sued Anthropic on that question last week. These six prompts are for establishing what you can and cannot say about the models in your stack, before someone asks. None of this is legal advice.

OpenAI put water systems and local government defenders first in its Daybreak pilot, and paired the access with training — because the constraint on a one-person security team is never detection, it is capacity to act on what gets found. These six prompts are built for that: triage over enumeration, and a defensible order rather than a longer list.

Sonnet 5 rose to 3 and 15 dollars per million today with a tokenizer change adding 10 to 35 percent more tokens on code, Claude Code weekly limits tighten on 14 September, and the GPT-5.6 Sol promotional rate reverts in November. Before moving a workload, it is usually cheaper to stop wasting tokens on the one you have. These six prompts find the waste.

Claude Code weekly limits settle 17 percent below current levels on 14 September, and OpenAI restored a five-hour cap on Codex. Neither publishes limits in tokens, so you find the ceiling by hitting it. These six prompts are about doing more inside a fixed allowance rather than paying for a bigger one, which is usually the cheaper fix.

Claude is exceptionally good at SEO tasks that require structured thinking — keyword clustering, meta tag writing, content briefs, and title optimization. These prompts are built for SEO professionals and content teams.
