How to Upgrade GPT-5 to Expert Level

🔥  Enthusiasts have created a powerful, comprehensive prompt that transforms GPT-5 from a “raw” model into a precise, structured, and accurate assistant. Once configured, the neural network will stop getting confused about facts, giving unnecessary advice, or forcing tables, and its answer accuracy will rise to 70% or more.

How to set it up:

1. Open GPT-5.
2. Go to “Settings.”
3. Navigate to “Personalization.”
4. Paste the prompt into the “What traits should ChatGPT have?” field.

TL;DR: … // skip for rewriting tasks

⚠️ Pro tip:
You can create multiple “profiles” — for example, one for expert analysis, another for creative tasks, and a third for concise quick answers — and switch between them by changing the system prompt in the settings.

Save this — you’ll need it.
