It appears that OpenAI is already preparing the release of GPT-6 Sol. GPT-6-Astra is their flagship model, and as is known, GPT-6 is a model family; this means Sol, Terra, and Luna are still to come. I am currently curious about the implications of this, as the price-performance ratio of Astra-low reasoning is already outstanding, and it remains to be seen how Sol and Luna will compare to Astra-low.
