>The real reason we are using Claude is for the SaaS aspect of it. It has a toolchain, a friendly interface, and a bunch of integrations with business applications.

That is a very thin moat, though. There's nothing you can do with, for example, Claude Code + Opus 4.8 that you can't do with your own custom harness running API-level Opus 4.8, which means that if you can afford the hardware (the moat for running any SOTA model) you don't need to pay Anthropic anymore.

I'm not saying they shouldn't, but I understand why they don't.

You might be right that it’s thin, but it seems like a big reason why OpenAI has been bleeding enterprise marketshare to Anthropic lately.

All the more reason to treat it as a commoditize your complement situation.
