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	Managed inference across 20+ open models behind one API Agent SDK for building on top of the hosted models Private AI Factory deployments inside a customer boundary Per-token pricing without GPU cluster management Image, text and multimodal generation endpoints
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	One API across a wide set of open models Removes GPU provisioning and serving-stack maintenance Private deployment path for regulated workloads
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	Region coverage and rate limits need checking for production traffic Agent SDK is newer than the inference product
Company	Avian Data Inc., founded 2022	FlexAI
