New GPT-5.6 hands-on experience

Comparison

I have already managed to test new models from OpenAI in codex.

My conclusion at the moment: 5.6-Terra with medium effort works much better and more efficiently than 5.5 with xhigh effort.

I haven't tested Sol yet, there is an interesting task for her.

By the way, 5.6-Terra eats tokens very slowly. Or maybe I missed it and the limits were raised 🤷‍♂️
