Yes, I am mildly disappointed with these releases.

I expected a Fable 5 -> Opus 5 situation, where GPT 6 Sol would perform on par with GPT 6 Astra.

Instead it's more like a price cut on GPT 5.6 Sol, and I'll have to stick with Astra for my work.

The only thing I can hope for is that more users switching to the GPT 6 Sol model frees capacity, allowing OpenAI to hand out some usage resets.
