My inbox is filled with “What will happen in AI in 2026?”
There’s a simple answer to that, at least on the technology front. What’s happening in labs now happens in the mainstream in 2026. If you’re not paying attention to the labs, you’ll be blindsided by what happens in the real world.
I’ll give you one simple example. A recent research paper, “Gated Attention for Large Language Models: Non-linearity, Sparsity, and Attention-Sink-Free” won Best Paper at NeurIPS 2025 a couple of weeks ago. Why? It showed a relatively simple mathematical change (a sigmoid gate after Scaled Dot Product Attention in a transformers model) robustly increased AI’s performance.
The paper comes out of Alibaba’s Qwen labs team. If adopted by other labs, they could see massive efficiency gains; on average, the lab saw a 47% decrease in unnecessary resource waste by making the model behave differently, mathematically. This allows AI to pay more attention to what matters, get distracted less, and spread its attention out across the entire conversation instead of prioritizing what came first.
This, by the way, is just one of a dozen different major changes I’ve read about as I peruse the conference papers. These are architectural things, under the hood, stuff that the average user will never see but will impact how AI functions for them.
Alibaba’s Qwen 3 Next models already use the paper’s outputs (no surprise there), which is part of the reason why they punch well above their weight. Qwen3 Next 80B A3B is a model that you can run on a nice MacBook Pro. It is competitive with the current version of Google Gemini Flash and Anthropic Claude Haiku 4.5.
Think about that for a second. Better math means a model that is compact, efficient, and still exceptionally high performance – and one you don’t have to pay to use, if your computer can run it. That math change has made it into production in one model, but many others haven’t followed suit yet.
They will – if the power gains and efficiency gains prove themselves out, other shops will have no choice but to adopt it to stay competitive. It might not be soon, because retraining a model after making a fundamental architectural change requires a lot of resources, but if the math is solid, it will happen.
And it’ll probably happen in 2026. Which means that the speed at which AI advances won’t taper off. We haven’t hit diminishing returns on it yet, largely thanks to better math. So if you’re amazed at what AI can do today, know that in 2026, it will be even more capable. And if you’re concerned about what AI can do today, know that in 2026, you will be even more concerned.
