I'll think about it if/when it happens - the space changes so quickly that whatever your plan is now, by the time you need the plan, everything will have changed so much that your current plan will be completely irrelevant.

And having to pay more and/or using slightly less capable models isn't a disaster, it's not like you need a frontier model for everything.

This was a more relevant conversation six months, since then OpenAI have been much more competitive on price for top models, Anthropic much less so but they're showing some signs of improvement in the 5.5 releases, and we've had an abundance of cheaper open source models.
