They should sell an add-on to your subscription so that if Claude is down it routes the queries to OpenAI. Then OpenAI can do the reverse for their subscriptions, and if both are down, Grok will invest your portfolio into Nvidia.

I do that already because it's good to have other models to ground Claude. You can do a lot with the $20 plan on Codex as backup

combine Codex with Cursor. both are really good. no other subs are worth it.
