.prompt files

Our file format for serialising prompts to store alongside your source code.

Our .prompt file format is a serialized version of a model config that is designed to be human-readable and suitable for checking into your version control systems alongside your code.

Format

The .prompt file is heavily inspired by MDX, with model and hyperparameters specified in a YAML header alongside a JSX-inspired format for your Chat Template.

Basic examples

Multi-modality and Images

Images can be specified using nested <image> tags within a <user> message. To specify text alongside the image, use a <text> tag.

Tools, tool calls and tool responses

Specify the tools available to the model as a JSON list in the YAML header.

Tool calls in assistant messages can be added with nested <tool> tags. A <tool> tag within an <assistant> tag denotes a tool call of type: "function", and requires the attributes name and id. The text wrapped in a <tool> tag should be a JSON-formatted string containing the tool call’s arguments.

Tool call responses can then be added with <tool> tags after the <assistant> message.
