Fable 5.1 being 6x cheaper than Astra for my actual usage was NOT what I expected. Here's the break down of cost per request: All xhigh, 1M context Fable 5.1: $0.19 Astra: $1.20 Sol: $0.30 Opus 5: $0.20 One thing I notice was Fable does caching really well for long context window while Astra just burns through credits LOL. Kinda shows why benchmark vs cost doesn’t tell the whole story. Your own workflow can completely change the result. Anyways, Sol was better for coding than GPT 6 Astra.
