FAQ

Which AI models have the longest context window?
The 25 models here all offer a 128K-token context or larger; they're ordered by window size, with SpaceXAI: Grok 4.20 Multi-Agent among the largest. Each is callable through one API.
Why does context window matter?
A larger context lets a model read more at once. Whole documents, large codebases or long chats, without truncation.
