One API key for hundreds of AI models from every major provider
Six hundred plus models for text, image, video, audio, transcription, embeddings, and reranking behind one OpenAI-compatible API.
Requests are rerouted to another provider on outages or rate limits by default, so you don't write custom retry logic.
The auto-router selects a model and provider per request using live marketplace performance and pricing data.
Track spend, tokens, and usage per model, provider, and team member in one place, including bring-your-own-key usage.
Run and scale durable AI agents on your own infrastructure
Every Actor gets a SQLite database and a filesystem, so an agent's memory and progress survive restarts and idle periods without a separate database.
Run untrusted or AI-generated code on your own infrastructure with fine-grained control over network access, filesystem permissions, and resource limits.
A node failure reschedules its Actors elsewhere with state intact, and multi-step work replays after a crash — with no checkpointing harness to build yourself.
Address an Actor directly over HTTP or hold a live WebSocket, and use the React SDK to subscribe components to an Actor's state in real time.
