Prompts that actually work

Two price moves in two days, and neither is readable from a per-token table. Claude Sonnet 5.5 kept identical pricing while cutting cost per task up to 30% through fewer tokens and batched tool calls. GPT-6.1 Sol claims parity with Astra on coding and computer use at one fifth the token cost, launched beside a $500-a-month tier whose speed mode charges up to 6x. The only number that settles any of it is what one finished task costs you. These five prompts work it out.

OpenAI says Astra scored 100% on ExploitBench and found two previously unknown zero-days during evaluation - the first model to meet the Critical cybersecurity threshold in its Preparedness Framework. Most patch policies were written when discovering a novel vulnerability was slow and expensive. These five prompts surface where your timelines quietly depend on that assumption.

Five prompts for building and stress-testing a voice agent on Grok Voice 3.0. Written for the Voice Agent API at $0.08 per minute, where every extra turn costs money, so each one is aimed at cutting call length rather than making the agent sound friendlier.

Eight states sued OpenAI this week alleging ChatGPT was marketed as safe while its risks were withheld. Whatever the outcome, the practical lesson for anyone buying AI is that a vendor's safety page is marketing copy until you test it. These five prompts turn a vendor's own claims into questions you can check — run them against the vendor's documentation, not against the vendor's chatbot.

Fish Audio's Drama 3 landed this week at 93.2% on a pronunciation robustness benchmark — which tells you about pronunciation robustness and nothing else. Benchmark scores do not predict whether a voice works for your script, your languages or your budget. These five prompts build the test set a leaderboard cannot give you.

Listed price per million tokens is not what you pay. Tokenizers differ between model families, some providers rebill an entire request once input crosses a threshold, and cache pricing varies by more than 5x. These prompts turn a pricing page into the number that lands on your invoice. Paste the pricing page text in with each prompt.

ChatGPT is fast, flexible, and excellent for coding tasks ranging from quick scripts to full feature implementation. These prompts are optimized for GPT-4o and work well across ChatGPT Plus and the API.

GitHub Copilot drops Claude Opus 4.8, Claude Opus 5 and GPT-5.6 Terra on 16 November 2026. Model retirements now land every few months, and the expensive failure is never the switch itself — it is a pinned model name that silently falls back to a default and quietly degrades your output for a week. These four prompts make the migration boring.

ChatGPT is the most versatile writing assistant available in 2026. These prompts cover blog writing, copywriting, emails, social media, and creative writing — all tested on GPT-4o for quality output.
