Liquid Inference

Never overpay for a prompt again. Providers compete to answer your requests. You set your requirements, send ordinary OpenAI- or Anthropic-format requests, and pay the lowest offer that meets them.

How it works

1. Providers set their prices. Providers post a price per token for every model they serve. The winning offer's price is capped before the model starts.
2. You set the terms. Choose the models, regions, speed and minimum quality. Only providers that meet your terms compete.
3. The best offer wins. The lowest priced model that meets your requirements answers your request. You only pay for what you use.

Features

• Prices that change with supply and demand.
• Independent benchmarks of every provider, published.
• Itemized billing: what every request cost, line by line.
• Public price history for every model.

Questions

• What do I change in my code? Most OpenAI and Anthropic code changes in two places: the base URL and the API key. Model names must be names that the exchange lists. See Quickstart.
• Can a request cost more than I expect? No. The exchange fixes a price cap before the first token, and a job never costs more than the cap. You pay for the tokens that the job used. See Receipts.
• What does the exchange charge? Providers earn their own price. The exchange adds a fee: the larger of 5% of the provider's charge and a floor of 1 cent per million tokens, lower for a free offer of a model with a reference price. A job that fails before any output pays no fee. See Fees.
• Can I buy a fixed amount of capacity? Yes. A reservation is a monthly pool of tokens on one model from one provider, at a fixed monthly fee. Ask up to 20 providers for a quote, accept one and name it in a preset. Requests use the pool first, then the market. See Reservations.
• Does the exchange keep my prompts? No. It does not store the text of your requests or answers, except a prompt that you save in a workload. See Data handling.
• What if a provider fails during a request? Before any output, the exchange can try the next offer. After output starts it does not switch providers.
• Do I need a card to try it? No. A new workspace gets a starting credit.
