Personally, I think it's far more likely that a year from now either SotA models will have shifted elsewhere or Anthropic will have changed their pricing model to something less favorable than the current MAX plans. Either of those scenarios could suddenly result in the current Claude subscription models either not existing or no longer being the screaming deal they are now. I think it's exceedingly unlikely we see any major provider go to an unmetered business model any time soon.
And if you've built your entire workflow around tooling specific to Anthropic's services, suddenly you have an even bigger problem than just switching to a more cost effective provider. That's one of the bigger reasons I'm very skeptical of these wrappers around CC generally.
Even Claude Code itself isn't doing anything that couldn't and hasn't been done by other tools other than being tied to a really cheap way to use Claude.
