Umm, Sonnet 4.5 has a 1m context window option if you are using it through the api, and it works pretty well. I tend not to reach for it much these days because I prefer Opus 4.5 so much that I don't mind the added pain of clearing context, but it's perfectly usable. I'm very excited I'll get this from Opus now too.
If you're getting on along with 4.5, then that suggests you don't actually need the large context window, for your use. If that's true, what's the clear tell that it's working well? Am I misunderstanding?
Did they solve the "lost in the middle" problem? Proof will be in the pudding, I suppose. But that number alone isn't all that meaningful for many practical uses. Claude 4.5 often starts reverting bug fixes ~50k tokens back, which isn't a context window problem.
