The author notes that the current GPT-5.6 sol is already ahead of Fable 5 in STEM capabilities. Given that Astra looks significantly stronger, it is expected that the next model will push this gap even further.
Furthermore, they speculate that if the upcoming model utilizes a GPT-4.5-scale pretrain, it might also bring back the distinct taste and high writing quality that made GPT-4.5 one of the best models they've used.
