# Lazu

> Call Claude, GPT, Gemini and DeepSeek with one OpenAI-compatible API key. Pay as you go, no subscription. The stable lane runs on official APIs, every request is itemized, and Lazu never trains on your data.

## Key facts

- OpenAI-compatible at `https://api.lazu.ai/v1/*` — change `base_url` and reuse official SDKs
- Native provider endpoints also supported (Anthropic Messages and Gemini)
- No more signing up with every provider
- Give everyone a cap that actually stops
- One key per person, so a leak costs one key
- A bill you can read and hand to finance
- Automatic failover on upstream error

## Lazu Studio

Lazu Studio is the image and video creation app on Lazu: many image and video models in one place, the same prompt tried across models, pay per image or per second from a prepaid balance, no subscription.

- [Lazu Studio](https://lazu.ai/studio): the prompt box to make an image, and the wall of public works with their prompts, models and sizes; filter by kind, model and aspect ratio
- [Models](https://lazu.ai/studio/models): every Studio image and video model, each with sample works and its price per image or per second
- [Pricing](https://lazu.ai/studio/pricing): top-up amounts and each model's price by size, quality or duration
- Each public work has its own page at `https://lazu.ai/studio/works/<id>` with the full prompt, model, size and date; creators who chose to be credited have a profile at `https://lazu.ai/studio/u/<handle>`
- Side-by-side comparisons of two models on the same prompt: `https://lazu.ai/studio/compare/<model-a>-vs-<model-b>`
