Do AI models still keep getting better, or have they plateaued?

The AI hype is based on the assumption that the frontier AI labs are producing better and better foundational models at an accelerating pace. Is that really true, or are people just in sort of a mass psychosis because AI models have become so good at mimicking human behavior that we unconsciously attribute increasing intelligence to them? I decided to conduct a mini-benchmark of my own to find out if the latest and greatest AI models are actually really good or not.\n

I tested 9 flagships (Claude 4.6, GPT-5.2, Gemini 3.1 Pro, Kimi K2.5, etc.) in my own mini-benchmark with novel tasks, web search disabled and zero training contamination and no cheating possible.

TL;DR: Claude 4.6 is currently the best reasoning model, GPT-5.2 is overrated, and open-source is catching up fast, in particular Moonshot.ai’s Kimi K2.5 seems very capable.

    It’s not about a solution. It’s about how they react.

    Fist, this “puzzle” is missing the constraints on purpose so “smart” thing to do would be to point that out and ask for them. LLMs are stupid and are easily tricked into thinking it’s a valid puzzle. They will “solve it” even though there’s no logical solution. It’s a nonsense problem.

    Older models would straight out refuse to solve it because the questions is to controversial. When asked why it’s controversial they would refuse to elaborate.

    Newer model hallucinate constraints. You have two options here. Some models assume “priest can’t stay with a child” which indicates funny bias ingrained in the model. Some models claim there are no constraints at all. I haven’t seen a model which hallucinate only “child can’t stay with candy” constraint and respond correctly.

    Sonnet 4.6, one of the best models out there claims that “child can stay alone with candy because children can’t eat candy”. When I pointed out that that’s dumb it introduced this constraint and replied with:

    That’s one of the best models out there…
