Rumours are circulating that GPT-6 Sol is about to be released, which aligns with Tibo's statement that numerous major releases are scheduled for this week, enough to fill a Dev Day.

As I understand it, GPT-6 Sol will be positioned below Astra, just as Opus is below Fable in the tier. Of course, the question arises: why?

My guess is that GPT-6 Sol will offer significantly better value for money than Astra. It will likely be close to Astra's performance, but similar to Opus, with better rates and costs. At the same time, I'm equally excited for GPT-6 Luna, as version 5.6 Luna was incredibly good in terms of both price and performance.

But who knows: perhaps we'll be surprised, and Sol will even be better than Astra in some aspects, with Astra receiving its next iterative update soon. After all, their internal model demonstrates how quickly improvements can be achieved through post-training.

With Opus 5.2 just around the corner, the update cadence continues. It remains exciting!
