If youโ€™re using ChatGPT, how you prompt makes all the difference. The latest GPT-4.1 guide is out - here are my highlights.

GPT-4.1 brings some ๐—บ๐—ฎ๐—ท๐—ผ๐—ฟ ๐—ฐ๐—ต๐—ฎ๐—ป๐—ด๐—ฒ๐˜€:

โ€ข Instruction Following: More literal and precise responses
โ€ข Tool Use: Better integration with APIs and functions
โ€ข Long-Context Handling: Can process much larger documents (up to 1 million tokens)
โ€ข Multi-Step Workflows: More effective for agent-like tasks and business logic

These are my key prompting takeaways:

The model follows instructions more literally than previous versions. A single clear sentence often fixes unintended behaviour.

GPT-4.1 is ideal for multi-step tasks. For agents, include reminders to:
โ€ข Keep going until the task is solved
โ€ข Use tools rather than guessing
โ€ข Plan and reflect between steps

Use OpenAIโ€™s tool API directly - no need for workarounds. Clear tool names and concise descriptions improve results.

๐Ÿ”น ๐—ฃ๐—ฟ๐—ผ๐—บ๐—ฝ๐˜๐—ถ๐—ป๐—ด ๐—ณ๐—ผ๐—ฟ ๐—ฝ๐—น๐—ฎ๐—ป๐—ป๐—ถ๐—ป๐—ด
Want the model to โ€œthink aloudโ€? Ask it to break down tasks step-by-step. This improves accuracy and depth, especially for complex problems.

๐Ÿ”น ๐—Ÿ๐—ฎ๐—ฟ๐—ด๐—ฒ-๐˜€๐—ฐ๐—ฎ๐—น๐—ฒ ๐—ถ๐—ป๐—ฝ๐˜‚๐˜ ๐—ต๐—ฎ๐—ป๐—ฑ๐—น๐—ถ๐—ป๐—ด
It can handle up to 1 million tokens, but performance depends on how you structure the input. Place instructions before the content and keep formatting clean and focused.

๐Ÿ”น ๐—œ๐—ป๐˜€๐˜๐—ฟ๐˜‚๐—ฐ๐˜๐—ถ๐—ผ๐—ป ๐—ฒ๐—ป๐—ด๐—ถ๐—ป๐—ฒ๐—ฒ๐—ฟ๐—ถ๐—ป๐—ด
Older prompts may not work the same. GPT-4.1 relies less on implied rulesโ€”be explicit about desired output, structure, and tone.

๐—•๐—ผ๐˜๐˜๐—ผ๐—บ ๐—น๐—ถ๐—ป๐—ฒ: GPT-4.1 is highly steerable - but only if you guide it precisely. Build structured prompts, plan agent workflows, and iterate often. Smart prompting is now a skill - and a competitive advantage.
