Description

Type: Bug

When using Claude Opus 4.6, I can set a 200k context size, but the right hand side Context Window dial presumes all chats use 1M tokens. When I'm at 78k of context, I expect the dial and metricts to be 38% full not, 8% full.

Not only is the dial misleading, it actually encourages developers to submit more requests at a higher cost when instead they should be compacting, or starting new chats. As we know, more context means 'lost in the middle' problems and performance degredation. Please address.

Thanks.
