Fable 5.1 has been observed to outperform Fable 5, Opus 5, and GPT-5.6 Sol, with its results described as almost impressive. However, the cost associated with Fable 5.1 is considered unacceptably high, a characteristic attributed to Anthropic's DNA. This performance and cost dynamic raises the question of whether it is time to reveal GPT-6 Astra, particularly if it can offer similar gains at a lower cost.
I tried Fable 5.1 and I can confirm it already surpasses Fable 5, Opus 5, and GPT‑5.6 Sol. While its results are ALMOST impressive, but he cost of Fable 5.1 is unacceptably too high(the DNA of Anthropic and its weak point).
Considering Astra’s evaluations by OpenAI HERE show dramatically better optimization and token efficiency than GPT‑5.6 Sol, the moment seems right to unveil GPT‑6 Astra with a more cost‑effective profile.
Isn’t it time to reveal GPT‑6 Astra, especially if it can deliver those gains at a real lower cost?
