Pesto··on Advancing the price-performance frontier with GPT‑5.6
I truly wonder what kind of model is luna now.

Before I thought it was just an improved version or at least in the same class as gpt 5.4 mini but now it's being priced like a nano model!

I thought about it because Terra has similar pricing to 5.4 and Sol is similar to 5.5.

Luna was already my workhorse before, it performs very well on high/xhigh for most of the tasks, very happy about this drop.

The bigger models are usually worse though, hopefully they nail it this time.
Pesto··on The Kimi K3 Moment
I think the biggest problem with Chinese models is that they seems to overthink for most of the tasks, especially for smaller ones. The OpenAI models have in my experience only gotten better in terms of efficiency.
