Key features	OpenAI-compatible API for open-source frontier models (DeepSeek, Kimi, GLM, MiniMax) Pay-per-token billing with no subscription or minimum monthly commitment Infrastructure hosting removes the need to self-manage GPU deployment for these models Multiple model families available behind a single consistent API interface Pricing starting near $0.105 per million tokens depending on model choice	200+ models behind one OpenAI-compatible API Smart routing to the lowest-cost available channel Multi-key budget control with per-key credit caps Text, image, video and editing models in one balance Per-model pricing published openly
Pros	OpenAI-compatible API means minimal code changes for teams already using that interface pattern Pay-per-token pricing avoids paying for idle capacity between usage spikes Access to several current open-source frontier models behind one API instead of managing several accounts	Per-key caps make a shared balance survivable for a team Publishes real per-model rates instead of a credit abstraction One integration across text, image and video vendors
Cons	No free tier, every API call consumes paid credit from the first request Usage-based pricing makes monthly cost harder to predict than a flat subscription Limited to open-source model families; no access to closed frontier models like GPT or Claude through this API	An aggregator sits between you and each provider's terms and uptime Cheapest-channel routing obscures which channel served a request No company entity named
