Chat in the browser

Use every model in a browser chat on the same account and balance as the API. Sign-in, models, editing and exporting chats, where chats are stored and how replies are billed.

You do not need to write code to try the models. Chat is a browser chat app on the same account as the API: sign in once and every model is available, billed to the same balance at the same per-token rates.

Start a conversation

  1. Open Chat. Signed out, you can already type your first message; when you send it, you are taken to sign in and brought back to Chat with your message still in the box. If you do not have an account yet, sign up. New accounts start at $0; models become available once the account has paid $3 or more.
  2. Pick a model in the model picker at the top. It shows each model’s input and output rate.
  3. Type your message and press Enter to send (Shift+Enter for a new line). The reply streams in as it is written.

You can also open Chat with a model already chosen by adding ?model=<id> to the URL, for example from a model page.

While you chat

  • Stop (or Esc) ends a reply at once. The partial reply stays, marked as stopped.
  • Regenerate asks the model again for the last reply.
  • Edit on one of your messages changes it and sends it again; the replies after it are replaced.
  • Copy copies a message as text.
  • Conversation settings set a system prompt (pick a preset or write your own) and the temperature for this chat. They are saved with the chat.
  • You can switch the model in the middle of a chat; each reply records which model wrote it.

Your chats

  • Chats are stored in this browser only, not on our servers. They do not sync between browsers or devices, and clearing your browser data deletes them.
  • The chat list lets you search (Ctrl+K, or Cmd+K on a Mac), rename and delete chats.
  • Export chat downloads the open chat as Markdown (.md) or JSON (.json). Export chats you want to keep before you clear your browser.

How chat is billed

Chat requests run through the same gateway and the same rates as API requests. There is no separate chat subscription.

  • Paid models cost the published per-token rate from the models table, charged to your balance. Each reply shows what it cost.
  • Free models, when any are listed, cost $0 and work at a $0 balance once the account has paid $3 or more.
  • Usage is logged. Chat requests appear on the usage page next to your API requests, under a key name that starts with playground-. You do not need to create an API key to chat.
  • When your balance is empty, paid models are refused with a link to add credit.
