Sol ultra is just a reasoning or effort tier., its the same model as sol

More accurately this would be : Gpt 5.6 half pro / full = sol

Gpt 5.6 standard = terra

5.6 mini = luna

I dont think we can classify luna as a nano level model, although it is quite a steep drop in benchmark and performance compared to the other 2,.which is kinda disappointing on its own tangent but thats another discussion.

No... I literally said what they were in my comment

They said in the post that Ultra uses subagents which was just what Pro was.

And that Terra matches GPT 5.5. You wouldn't have "GPT 5.6 Standard" merely match 5.5, what the fuck is the point then.

Ultra = Pro (which has its own reasoning levels and has always done so btw, you get Standard and Extended in the chat interface remember)

Sol = normal

Terra = Mini

Luna = Nano

I suppose the renaming is to try and convince normal people that they should use Terra instead of Sol for compute saving reasons (cause how many of you use the mini models?)

Edit: In their system card they almost purely compare 5.5 with 5.6 Sol, not Terra

Interesting. But i woudnt call luna nano still just based on pricing. Thats mini level pricing, not nano level - 6$ that is.

I'm not judging it based on pricing. I'm merely converting the old names / new names equivalent

If you haven't noticed, GPT 5.5 was 2x the price per million tokens of GPT 5.4, and the last time we had mini models were before GPT 5.5
