Frontier intelligence

Choose the best AI for every task – from OpenAI, Anthropic, Google, and open-source labs.

Zo runs on the most capable AI models in the world. Models from Anthropic, OpenAI, Google, and open-source labs – with new models added as they ship.

No lock-in

Switch between models anytime. Different models have different strengths: some are better at writing, others at coding, others at working with images or long documents. Use the best one for the task at hand.

Bring your own

Already have API keys? Use them. Zo supports any OpenAI-compatible endpoint, so you can connect to your preferred provider – including self-hosted and open-source models.

Your AI, your choice.
