What it does

The Kilo AI Gateway gives one OpenAI-compatible endpoint for several hundred language models from many providers, so an application can switch models without code changes. POST JSON to /api/v1/chat/completions; the model kilo-auto/free picks a free model automatically. Free without a key for models tagged :free, up to 200 requests per hour per IP address; other models need a Kilo API key and paid credits. The list of free models changes, and some ask that data collection is allowed.
