Opus 5.5 will make you feel Astra is even more expensive and this might be the first time Claude model would feel cheaper than GPT while giving similar performance apparently Opus 5.5 is expected to be priced at $4 input / $20 output which makes it cheaper than Astra as well as Fable 5 and Opus 5 this itself makes it a really great model, unless OpenAI surprises us with GPT-6 Sol’s cost-to-performance ratio
