What is Parasail?

Parasail is an inference cloud built for AI-native startups, serving trillions of tokens daily. It provides a single OpenAI-compatible endpoint to access 40+ open and frontier models, including fine-tunes and custom architectures. The platform focuses on reliability, performance, and flexible capacity so teams can scale inference without managing idle GPUs.
