What issue are you seeing?
When I run out of usage during an auto compact, it is not letting me change the model to get-5.3 spark even though I still have 100% usage for 5.3 spark. Well it does let me change the model but it just says it ran out of usage. It states "Error running remote compact task: You've hit your usage limit". I suspect because the compact task is still stuck on the 5.6 model.
What steps can reproduce the bug?
Run out of usage during a compact while on 5.6, then switch the model to 5.3 spark (which still has usage) and try to prompt 5.3 spark.
What is the expected behavior?

@antoineeliux OpenAI support already explained it previously that Spark uses non-Spark limits and model for context compaction, even if its not really obvious from the docs
