Pick a model, or let Singular pick

Choose the exact model you want, or leave it on Auto and Singular routes each question to a model that fits. Not happy with the answer? Regenerate with another model and keep both in the thread.

Compare models side by side

Ask one question and see how different models answer it, next to each other. Compare quality, speed, and price in one place instead of five tabs.

See what every answer costs

Each response shows the model used, the cost, the time it took, and the sources it read. Prices are per million tokens and match the live catalog. Nothing is hidden.

Use it in the app or through the API

The Singular API speaks OpenAI Chat Completions, including for Claude models. Point your existing code at Singular with one key and reach every model in the catalog.

What is Singular?

A unified interface to 950+ AI models across chat, image, audio, and video. You get one balance for all of them, with auto-routing, side-by-side comparison, citations, and a cost on every answer.

Which models can I use?

Models from OpenAI, Anthropic, Google, DeepSeek, xAI, Meta, ZAI, Moonshot, Xiaomi MiMo, and more. The full list and live prices are on the Models page.

How does Auto routing work?

Singular looks at your question and sends it to a model that balances cost, speed, and capability. You can always override it and pick a model yourself.

How much does it cost?

You pay each model's published rate from a prepaid balance, plus a published fee for each web search or page fetch. There is no monthly fee. You see the cost of every answer as it is spent.

Can I use my own API keys?

Yes. Attach your own provider keys in Settings and matching requests use your credential. Those requests are still billed to your Singular credit.

Is there a free trial?

Yes. New accounts get $1.50 in free credit with no credit card.

Can I use Singular from my own code?

Yes. The API uses OpenAI-style Chat Completions requests, including for Claude models. See the API page.
