Your vendors plans to grow fast and break things shouldn’t affect your ability to provide your service to your customers.
Anthropic has not been a reliable vendor. Previously, when they were compute starved, the quality of their models degraded in the weeks before new releases, without warning to their customers. You just suddenly got a worse service. I wrote a little more a few months ago: https://news.ycombinator.com/item?id=47375818 And then there’s the transparent downgrading they did with Fable.
If your running a business, that’s not what you want to be relying on.
