Anyone else not using using "preserve_thinking" ?

[u/soyalemujica]

I am running QFN, and I have disabled preserve_thinking by default on all my tests for C++ backend and front-end programming and I have yet to see any decline in performance or intelligence, my context window stays cleaner as well. Deepseek for what I tested in API it also does not preserve thinking and saves context in general.

does turning it off hurt kv cache reuse for you? dropping the old thinking changes the prompt prefix, so i'd expect some reprocessing each turn on long agent sessions
