Prompt Optimizer upgrades an existing prompt into a clearer, more structured version and saves a history of improvements.

​
When to use it

Use Prompt Optimizer when you already have a prompt and want to:
  • Improve clarity and structure
  • Add constraints and acceptance criteria
  • Make the output format explicit (JSON, table, checklist)
  • Create a stronger “system prompt” style instruction set

​
How it works

  • Paste your prompt, or choose one from My Prompts to auto-fill.
  • Select the optimizer model (the assistant that performs the rewrite).
Each optimization is saved automatically to History with:
  • Original prompt
  • Optimized prompt
  • Timestamp
Pinned items stay at the top.
Use Run on a history card to open a new Assistant chat seeded with the optimized prompt.

​
Optimize a prompt

1

Start with a solid base prompt

If your prompt is vague, add:
  • Who the model should act as (role)
  • The context and constraints
  • The expected output format
2

Choose an optimizer model

Pick the model you want to use to perform the rewrite.
3

Click Optimize

Prompt Builder generates an improved version and saves it to History automatically.

​
Tips for best results

  • Prefer concrete inputs: include examples, edge cases, and “don’t do” constraints.
  • If you need a strict format, say so (and include a schema).
  • Use short follow-up optimizations instead of one massive prompt rewrite.
