Why would they price it the same as Fable it it doesn't cost the same as Fable ?

That's half my point - Anthropic's remarks suggest that is Fable significantly bigger (hence more costly to run) than Opus, so it is priced accordingly, but GPT 5.6 priced the same as 5.5 is one datapoint that suggests they are the same size.
Yeah...and why would being the same size mean anything ? This is par the course for Open AI. They've always been cheaper and likely smaller than Opus models even when they weren't much if any worse.
> why would being the same size mean anything
Because these companies are still 100% scale-pilled, and each new generation of model is bigger than the previous one, even if active parameters (MoE) is growing slower than total parameters. There is also scaling in inference-time compute which adds to the cost just the same. Fable is rumored to use variable compute which will increase the cost for inputs that get routed for more compute.
Maybe as you suggest the OpenAI pricing is unrelated to size/cost, but if so it seems a very aggressive move given that models that cost more to train and run need to generate more revenue to be profitable.
