> The context window is very important.

It is everything. My experience with Claude Code is that you have to decide when to compact to make it efficient. It defaults everything to 1M context and it will never keep it in check. It is strange how little cache reads you hit in smol, that may be a configuration issue.

I will look into it more to see if I have configured it wrong but I think the token efficiency hurts cache use as caching only starts at 1024 tokens so for tasks where smol is under or close to 1024 tokens most of them are uncached

There's an env var you can set to tell it when to compact. It's especially helpful for models with big context that lose coherence much earlier.
