zeldoc-pi-provider

Zeldoc.ai model provider for the Pi coding agent.

Registers zeldoc as a provider in Pi and discovers every model your Zeldoc.ai API key can use, so you can pick ZDev or any router model from /model.

Install

pi install npm:zeldoc-pi-provider

Or straight from GitHub:

pi install https://github.com/martinmose/zeldoc-pi-provider

Authenticate

Either export your API key before starting Pi:

export ZELDOC_API_KEY=your-api-key

Or store it in Pi: start pi, run /login, pick Zeldoc.ai, and paste the key.

Don't have a key yet? See Generate an API key.

Use

Start pi, run /model, and pick a model under Zeldoc.ai. ZDev is available immediately; the rest of your catalog appears after the first refresh (a few seconds after startup). To make ZDev the default, add to ~/.pi/agent/settings.json:

{
  "defaultProvider": "zeldoc",
  "defaultModel": "zdev",
  "defaultThinkingLevel": "high"
}

Thinking levels are wired up per model: ZDev and ZDev 2 expose low, high, and max, and models served through the Zeldoc.ai router (GPT, Gemini, ...) get the effort levels published on models.dev.

Limit which models are shown

Zeldoc.ai's catalog includes image, audio, and embedding models. Those are filtered out automatically. To narrow the list further, add substrings to match in ~/.pi/agent/settings.json:

{
  "zeldoc.models": ["zdev", "gpt-5"]
}

Only model ids containing one of the substrings are registered, so "zdev" keeps every ZDev model. Pi's own enabledModels setting still applies on top for Ctrl+P cycling.

How it works

• The ZDev models are registered synchronously with their known limits (1M context, 131k output), so pi --model zeldoc/zdev works even before the catalog has been fetched.
• On startup Pi asks the provider to refresh. The extension calls GET /v1/models on Zeldoc.ai, enriches the result with reasoning metadata from models.dev (cached for 7 days under ~/.pi/agent/cache/), and persists the catalog in Pi's models store. Later sessions load from the store and re-fetch at most once an hour, or immediately with pi update --models.
• Set ZELDOC_PI_PROVIDER_DEBUG=1 to trace refreshes on stderr.

Development

pnpm install
pnpm check        # tsc --noEmit
pnpm format       # biome check
pnpm format:fix   # biome auto-fix

Try a local checkout without installing it:

pi --no-extensions -e ./extensions/zeldoc.ts --model zeldoc/zdev
