If both of them are down at the same time, I would switch to my Kimi or GLM subscription and keep working. If they fail too, I switch to any number of providers via OpenRouter.

While there is some lock-in for the hardest tasks, for most of what people do LLMs are rapidly becoming a commodity.

In fact, right this minute I have Opus benchmarking Kimi alongside itself to determine which workflows we'll switch to using Kimi by default and Opus as the fallback instead of vice versa. It has already conceded Kimi does better on several tasks.
