ChatGPT (GPT-6 Astra, Sol, Luna) benefits from instruction-first prompts with delimiters and clear acceptance criteria. Astra does best with the goal and constraints; Sol and Luna do best with explicit steps and an exact format.

Promptea structures prompts the way GPT expects them and adapts the depth to the use case you pick.

Open the analyzer with GPT selected, paste your draft and choose the GPT model you will use. Promptea optimizes the prompt for it; it does not run it. The GPT page lists the current models with their verified capabilities and the date of that verification.

- Instruction-first ordering with explicit delimiters.
- Acceptance criteria block when the task benefits from it.
- Sub-model awareness for reasoning vs general models.
