Strange that the page https://artificialanalysis.ai/agents/coding-agents doesn't even mention "Qwen" once if it's now the "best" according to one of their one index?
Does "artificial analysis" mean what it says? Dubious.
But: I've been very impressed by the larger Qwen Models, and a brief try of Kimi also impressed me.
A lingering sense of quality degradation when going deep remains.
But that's not an accusation: they seem to be hitting the compute/quality tradeoff extremely well.
And on-prem capability is simply irreplaceable.
Apart from all the innovations that were driven by the strive for this optimization: quantization, "distilling" (without obvious mad-cows-disease)... I think China was an invaluable player in this progress. Intuitively, I'd even go so far to speculate that LLaMa wouldn't exist without the competition.
According to those graphs, Grok 4.5 appears to be the most cost-effective model.
Different benchmarks:
> Artificial Analysis Agentic Index: Represents the weighted average of agentic capabilities benchmarks in the Artificial Analysis Intelligence Index (GDPval-AA v2, Tau³-Banking)
> Artificial Analysis Coding Agent Index v1.3 incorporates 3 benchmarks: DeepSWE, Terminal-Bench v2, and SWE-Atlas-QnA
Qwen3.8 Max is 55.4 on the Agentic Index but hasn't been tested for the Coding Agent Index.
Indeed, and this Qwen 3.8 max specific page:
https://artificialanalysis.ai/models/qwen3-8-max
Doesn't have the claim either. Clickbait?
They didn't run all benchmarks. It's the best in AA agentic index (GDPval-AA v2, ³-Banking) but not coding index (DeepSWE which is missing, Terminal-Bench v2.1 they have 81% vs 90% for Sol, SWE-Atlas-QnA missing).
