Context Window Visualiser
Compare context window sizes across 8 major AI models with interactive usage simulation.
Visual comparison of context window sizes for the major AI models. Slide the usage control to see how each model handles different fill levels.
Shows warning indicators at 80% capacity (yellow) and full capacity (red). Bars scale relative to the largest window so you can see the real differences between a 128K model and a 1M model.
Useful for planning which model to use when you need to fit large documents, long conversations, or multi-file codebases into a single call.
