Cloudflare Workers AI provider for pi

A pi package that registers Cloudflare Workers AI as the cloudflare-workers-ai model provider.

The extension uses Cloudflare's OpenAI-compatible Chat Completions endpoint and includes the Workers AI model catalog with reasoning, image-input, context-window, output-limit, pricing, and compatibility metadata.

Requirements

Set both variables before starting pi:

export CLOUDFLARE_ACCOUNT_ID="your-account-id"
export CLOUDFLARE_API_KEY="your-api-token"

The API token must have permission to run Workers AI models for the account.

Install

pi install npm:pi-extension-cloudflare-workers-ai

The npm: scheme is required; a bare name is interpreted as a local directory path.

Install locally

pi install ~/pi-extension-cloudflare-workers-ai

Local package installs reference the directory in place. Restart pi after changing CLOUDFLARE_ACCOUNT_ID, because the account-specific endpoint is assembled when the extension loads.

To try the package without installing it:

pi --no-extensions -e ./src/index.ts --list-models cloudflare-workers-ai

Use

Start pi and open /model, then select a model under cloudflare-workers-ai.

For example:

pi --provider cloudflare-workers-ai \
  --model '@cf/ibm-granite/granite-4.0-h-micro' \
  'Say hello'

Development check

npm run check

The extension is TypeScript loaded directly by pi; no build step is required.
