Context windows, ranked

A model's context window is the maximum number of tokens it can consider in a single request — your prompt, any documents you attach, and for most APIs the response too. This table ranks all 338 models by context length, with a plain-terms estimate of what actually fits. Not sure how many tokens your text is? Use the token calculator.

Pages assume ~0.75 words per token and 500 words per page — an approximation; real capacity varies by tokenizer and content. Each row links to the model's page with full specs, pricing, and code samples.
