What makes you think your usage is getting cut by 50% post July 13th? It's just that you can use up to 50% of your usage on Fable right now, and that is what is going away.

I'm going to miss Fable too, I found it surprisingly tough going back to Opus when we lost Fable first time round, but paying API costs is simply out of the question for me right now.

I guess to be more accurate, usage wouldn't get cut 50% but rather by 33.3% post July 13th.
