Prompts - MetrixLLM

The Prompts page is your central library for managing the prompts that power your AI features. Changes you make here take effect on live traffic within a few minutes, with no code deployments needed.

Creating a Prompt

Click New Prompt in the top right.
Give it a descriptive name (e.g. Customer Support Agent).
Write your system prompt in the editor.
Optionally define a model and temperature to use by default.
Click Save — this creates the first version (v1).

Version History

Every time you click Save, a new version is created. You can view the full version history by clicking the Versions tab on any prompt. To revert, click Set as Latest on any previous version.

Using a Prompt in Code

Once a prompt is saved, it has a unique Prompt ID (a UUID). Reference it in your gateway requests using the prompt_id field — the gateway resolves it automatically at runtime.

{
  "model": "gpt-4o",
  "prompt_id": "your-prompt-uuid",
  "messages": [{"role": "user", "content": "Hello!"}]
}
