Just get an OpenRouter or Vercel account. Your option aren't pay Anthropic or buy hardware yourself, there are hundreds of providers out there.

Claude has us locked in right now while they subsidize cheap usage to get us subscribed and dependent on their monthly plans.

As temporary backup, one can use claude models hosted on GCP - my understanding is that those don't depend on platform.claude.com and should be available even if main claude platform is dead

It depends on what "us" means. I am switched off of Claude almost entirely now except for background things where I want to abuse my subsidized account. Otherwise, OpenRouter + open weight models are my daily drivers. It takes a bunch of work but I'm doing it for roughly a max20 account cost, a bit more, but it's not like the difference is huge. They are less capable but I've modified my workflow to mitigate that as much as possible, and I can still do things when Anthropic goes down.

There is an absolute tonne of competition.

Only until NVIDIA starts cryptography verification and block anything not from US closed models, which should be anytime soon

I hope that doesn’t happen. There is a good alternative: if MOE models work for you, then Apple Silicon does a decent job at inference using whatever harnesses you like.
