You can enable the 1 million token context window and adjust when it compacts in your config.

> model_context_window = 1000000

> model_auto_compact_token_limit = 900000

I believe it does consume your usage a bit faster though.

Unless things changed this used to work but was blocked. You also used to be able to force in a model catalog to get around the token cap. Each, as of at least April, were closed off and ineffectual. I’ve not tried lately so you may be right.
