Prices are each provider's list price in US dollars per million tokens, before discounts, caching or batch rates. One current model per family is shown; previews, aliases and image, video, speech and embedding models are left out.
How we choose
The newest model is not always the right one
Tested on your examples
We run the same set of real examples through two or three candidate models and compare accuracy, speed and cost before choosing.
Mixed by task
A larger model for the hard steps and a smaller, cheaper one for routine requests usually beats one model for everything.
Easy to switch
Because quality is measured on every change, moving to a newer or cheaper model later is a measured decision, not a rewrite.
Questions
Reading the table
What does price per million tokens mean?
Providers charge by the token, roughly three quarters of a word. Input price covers what you send to the model, output price covers what it writes back. One million tokens is about 750,000 words.
What is a context window?
The amount of text, measured in tokens, a model can consider in one request, including your instructions, documents and its own reply. A 1M context window holds several long books at once.
Which AI model should we use?
It depends on the task, your data rules and your budget. We test a shortlist on your own examples and usually combine a larger model for hard steps with a smaller one for routine work.
How often is this list updated?
Automatically, every hour, from the open models.dev catalogue. Prices and limits come from each provider's published rates; check the provider's own page before committing to a budget.
Next step
Not sure which model fits?
Tell us the task. We'll test a shortlist on your own examples and tell you what it would cost to run, before anything is built.
