With open models, perhaps. But $100/week isn't going to get you 24/7 use of Claude Sonnet.

$100/week will get you both a higher tier of Claude and significantly more tokens with GLM5.1 or Kimi, both of which are competitive in a decent harness (for Kimi that means their own CLI - it works well in that, but has a lot of quirks that requires special treatment). Just slightly more will get you all three.

Enterprise accounts pay per token.

Of all the companies I've done work for over the last couple of years, only one have used an enterprise account.
