Auto-route, tag-based, direct selection, or failover chains. You control the strategy.

Every AI modality. One gateway.

From text to video, from speech to images — access the leading AI capabilities through a unified, OpenAI-compatible API.

Text & Language

LLM Chat

OpenAI-compatible chat completions. Access leading LLMs through a single endpoint with intelligent routing — auto, direct, tag-based, or failover.

Image to Text (OCR)

Extract text from images, receipts, documents, and screenshots. Multimodal understanding with contextual interpretation.

Audio

Transcribe audio and video files with high accuracy. Multi-language support, multiple formats.

Text to Speech

Natural-sounding speech synthesis. Multiple voices, languages, and styles for any use case.

Voice Clone

Image

Image Generation

Generate images from text prompts. Multiple aspect ratios, styles, and quality levels. Also supports image-to-image editing.

Image Edit

Transform existing images with text instructions. Inpainting, outpainting, style transfer, and intelligent editing.

Video

Text to Video

Generate videos from text descriptions. Async processing with status polling for production-ready workflows.

Image to Video

Digital Human

LLM Router: 4 routing strategies

One endpoint, multiple providers. Route to the best LLM for every task — automatically.

Auto

AI classifies your prompt and picks the optimal model by cost, speed, and complexity.

Direct

Choose the exact model yourself. Full control over which provider handles your request.

Tag Routes

Map tags like fast, smart, creative to pre-configured models.

Failover Chain

Chain multiple models with automatic failover. If the primary is unavailable, the next in line takes over.

OpenAI-compatible. Zero learning curve.

Switch from OpenAI to AI Gateway in one line. Same SDK, same format, more models.
