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.
One REST endpoint for SD 1.5, SDXL, Flux and 10,000+ community models
One POST endpoint handles text-to-image, image-to-image and editing jobs across SD 1.5, SDXL, Flux, ControlNet and LoRA models, with cURL, Python and Node samples for each model.
Thousands of community checkpoints and LoRAs, including anime, photorealistic and stylized families, are browsable with their parameters and sample code.
Requests return a job id or track id so long-running generations can be polled or pushed to your own webhook endpoint instead of blocking the client.
Dreambooth-style endpoints let you train custom concepts and styles on your own images, then reuse the resulting model ids in generation calls.
