What This Number Actually Means
A model's context window, measured in tokens, caps how much text it can consider at once across your entire conversation, not per message — see our Context Window Explained page for the full concept.
Checking a Specific Model's Current Limit
See individual model profiles in our Models directory for current, specific context window figures, since these can change as providers release updates.
