The reasoning model

Cobalt

Thinks a hard question through before it answers, so it misses fewer steps. Its replies take longer to start.

Picking who answers

Press the model name under the message box.

  1. Base AIs

    The four above. Atlas answers until you pick another.

  2. Team

    Pick two to five AIs. They answer, read each other and answer again, then one of them writes the final answer.

    1 credit for every answer they write: 7 for a Team of three.

  3. Your AIs

    Claude, Gemini, OpenAI, Grok, Mistral or OpenRouter, with an API key you add in Settings.

    That company bills you. The key stays in your browser.

Limits

They don’t always search

The web is only searched when the answer might have changed, like news or prices.

Facts can be wrong

Any of them can sound sure and still be wrong. Check the sources under an answer.

No images, audio or video

They can make PDF and Markdown files, tables and charts, but not images, sound or video.
