agreed. the claudes have been getting better and better with every release in this regard.

opus 4.5 would start failing tool calls when approaching its 200k limit, opus 4.6 could get to ~300k before getting confused, opus 4.7 i could stretch to around 400k the dumb zone started, with opus 4.8 i've had sessions get over 500k comfortably.

admittedly we only had limited time with fable, but i had a couple sessions get into 800-900k just fine.
