sol-6 is terra-6. They figure that no one was using terra and they could bring the speed and cost saving of terra distilled on astra, but rebranded as the more popular sol.

Back fired because of opus 5.5.

So now we get the real sol-6 as sol-6.1, and OpenAI will eat the cost to stay competitive.

This could be invalidated if sol-6.1 is the same speed as sol-6.

6.1 Sol is slower than 6 Sol: https://artificialanalysis.ai/models/releases/gpt-6-1-sol

However, that doesn't say much. You can just run a smaller model at a larger batch size to get higher throughput but lower interactivity.

It's not that terrible then if that's the case. 5.6 Sol was superb in my eyes, and while I've tried a million things, there hasn't been anything that 6 Astra improved or did better than 5.6 Sol, while costing a ton of time and resources. Including research topics, where it should have excelled. So even if 6.1 Sol is no worse than 5.6 but cheaper and faster, the gutted Pro200 might still make sense.
