pi-cohere

Pi provider extension for Cohere models.

Installation

pi install npm:@aliou/pi-cohere

Set the API key before use:

export COHERE_API_KEY=...

What it provides

Registers a cohere provider in Pi.
Uses Cohere HTTP endpoints directly, not the Cohere SDK.
Fetches chat-capable models from GET https://api.cohere.com/v1/models when COHERE_API_KEY is available.
Caches fetched models in Pi's model store and refreshes them through /model or pi update --models.
Falls back to a small hardcoded model list when model fetching is unavailable.
Uses Cohere's OpenAI-compatible endpoint at https://api.cohere.ai/compatibility/v1 with Pi's native openai-completions provider path.
Supports text, vision model metadata, tool calls, streamed usage, and context-overflow normalization.

Development

pnpm install
pnpm typecheck
pnpm lint

Layout

extensions/provider/: Pi extension entry point.
src/cohere/: Cohere model mapping and API helpers.

Notes

Cohere returns usage in response bodies and a num_tokens header for non-streaming chat. I did not see quota, remaining-credit, or rate-limit headers while probing.
