Models

Free models count calls; big models are charged by usage

• Claude, GPT and other big models are charged to your balance for the visible text you send and the text that comes back. Each model has its own price, listed on the Pricing page.
• Text you send is charged at 20% of the price of returned text. The part of it the provider bills as cached, such as earlier context sent again, is charged at 10% of the sent price. The estimate shown before sending does not count on the cache.
• A model’s own thinking is not charged. A reply that comes back empty is neither counted as a call nor charged.
• On big models an image is charged as 300 characters, once per conversation in the web chat.
• On big models, the text read from a file you attach is charged like the rest of the message, each time it goes with a question.
• Sign in with an email code, Google, GitHub or Discord. No password and no card needed.
• Claude, GPT and other big models are open to accounts that have topped up.
• Top up from $5. Your balance never expires, and nothing renews on its own.
• Up to 12 requests a minute per key.
• Free models: up to 30 calls in each 5-hour window per account, or 90 for 35 days after a payment. A long message counts as several calls: one for every 50,000 counted characters, and one more for any part left over. Characters are counted across the whole conversation sent, earlier messages included; each Chinese character counts as one, every 4 other characters as one.
