I cannot wait to be past this “here’s a matrix with 40 model options” phase of AI. No “normal” users can tell which choice is optimal for which task.

At this point model upgrades do not mean too much for an established use case. I have 36 benchmark scenarios using agents + tools in my app and the results were 30/36 for gpt 6 luna, and 33/36 for gpt 5.6 luna. The benchmark was tuned for gpt 5.6 luna but still apart from slightly reduced cost I will keep the default model to gpt 5.6.

Just what I was hoping for, very nice. Luna seems like a real replacement for DeepSeek on pricing. Haven't seen a comparison benchmark yet.

Luna is really good model that would have been super SOTA at the beginning of the year and its basically free at these prices.

So opus 5.5 has reduced price. Who is winning then?

Selling dollar bills for $0.40 to undercut the guys selling them for $0.50 is a bold move. Let's see if it pays off for them.

so opus 5.5 is smarter and cheaper than fable, and sol 6 is a little dumber and WAY cheaper than astra? is that right?

Very nice in cost/1mtok. Looks like more work is being done for efficient everyday helper models as time goes on.
