Introducing AI Gateway: One API Key for Every AI Modality
Today we're launching AI Gateway — the evolution of AI Stack. Same powerful capabilities, clearer vision: one API key for every AI modality your startup needs.
Why the rename?
AI Stack described what we built — a stack of AI tools. But "AI Gateway" better describes what you actually get: a single gateway to every AI capability, with one key, unified billing, and intelligent routing built in.
What's new
One API Key
No more managing separate provider accounts. Your LiteStartup API key now works across all modalities:
- LLM Chat — OpenAI-compatible
/ai/chat/completionswith 4 routing strategies - Image Generation — Text to image with multiple styles and aspect ratios
- Image Editing — Transform images with text instructions
- Video Generation — Text to video and image to video (async)
- Digital Human — Talking-head videos from a photo and audio
- Speech to Text — Transcribe audio and video files
- Text to Speech — Natural speech synthesis with voice cloning
- OCR — Extract text from images and documents
OpenAI-compatible
Switch from OpenAI to AI Gateway in one line. Same SDK, same request format:
curl https://api.litestartup.com/ai/chat/completions \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model": "auto", "messages": [{"role": "user", "content": "Hello!"}]}'
Smart LLM Routing
Four routing strategies for LLM requests:
| Strategy | Description |
|---|---|
| Auto | AI classifies your prompt and picks the best model |
| Direct | Choose the exact model yourself |
| Tag | Map tags like fast, smart, creative to models |
| Failover | Chain models with automatic fallback |
Uncensored Models
For creative professionals and adult content platforms, AI Gateway now offers access to uncensored image and video generation models with no content filters. Learn more →
