Unless SLA (or equivalent) is specifically mentioned in the T&S (which isn't), I don't see why Anthropic would ever compensate anyone. Measuring uptime and performance is meaningful and valuable, but expecting compensation is a completely different question.
If you don't like it, go use someone else's product. There are plenty of choices.
I'm using Jetbrain's AI Assistant (Junie, with different LLMs), and it also has frequent agent crashes (bye tokens) and sometimes is unreachable - albeit never longer than minutes so a few retries suffice. And even with the default Gemini 3 Flash I can easily burn through 10 or more bucks over a normal coding day (which is not every day, sometimes there's more reading). Do I still get value? Definitely. But it's not the easy life either.
All true, but also depends on jurisdiction the product is operating in
For example, in Australia any consumer has rights around products and services they purchased regardless of the terms agreed to during sale. If a business offered 99% uptime in their marketing, then they are required to provide that or, something equivalent, or a refund, even if it was never mentioned or some lower number was mentioned in the terms and conditions.
Enforcing that however, particularly with companies that are renowned for having no human staff, is tricky.
So yes, definitely agree - builders have to be aware of their dependencies and work with the realities of what they provide, not the theoretical
