GPT-6 Astra makes major gains in the Artificial Analysis Coding Agent Index

Title: "major gains"

First chart: from score 61 (GPT-5.6 Sol) to drumroll 61 (GPT-6 Astra)

Fascinating. This is the only benchmark I've seen so far with lack-luster results. I don't understand enough about AA's specific methodology to get the implications.

Well, seems like ECI [0] and the AA index is diverging quite a bit. Benchmarking LLM is tough and I think we are seeing the limitations of current benchmarks and applicability to real tasks.

In the general Intelligence Index it scores exactly equal to Sol (61). In the Agentic Index it scores significantly lower than Sol (51 vs 58). In both it scores lower than Fable 5.1, Opus 5 and even Muse Spark 1.3.

Am I missing something or is this not looking too... stellar?

more like 5.7 not 6
