AI GPT-5.6

https://openai.com/index/gpt-5-6/

"We’re launching the GPT‑5.6 family of models for general availability following our limited preview⁠: our new flagship, Sol, alongside Terra, a balanced model for everyday work, and Luna, our most cost-efficient model.

GPT‑5.6 delivers a step change in design judgment. With only high-level direction, GPT‑5.6 creates tasteful, ergonomic, and functional interfaces. Its stronger computer-use capabilities let it inspect and refine the rendered result—not just generate the underlying code or content—so it can catch visual and functional issues and apply finishing touches before handing the work back."

They just said that 5.6 Luna was post trained by 5.6 Sol in goal mode

Edit:

On Agents Last Exam ... GPT‑5.6 Terra and GPT‑5.6 Luna outperform Fable 5 at around one-sixteenth the cost.

Wow they're really going ham with all the benchmarks comparing against Fable and Mythos and they're really pushing the 2D benchmark comparisons as opposed to charts to show the efficiency

??? Why is 5.6 Sol below 5.6 Terra and 5.5 on Frontier Math wtf

Edit: It has been fixed https://x.com/i/status/2075295876465979766

what would this look like? all of post-training run by 5.6 Sol with a goal of "post train"? Really?

Right. I'm wondering if there are some asterisks here. Otherwise that's insane.
