Enterprise-grade gateway to hundreds of AI models through one API
One endpoint and one API key reach models from OpenAI, Anthropic, Google DeepMind and other vendors, removing the need to maintain separate integrations.
Requests can be routed to the most suitable or most cost-effective model automatically, with balancing across providers for stability.
Text/LLM, image generation, video generation, audio (speech recognition and synthesis) and specialised decision APIs are all available through the same interface.
Detailed performance and spend statistics let teams monitor cost, latency and usage per model or per key.
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.
