From a researcher/developer perspective: the biggest bottleneck that affects current-gen AI is the lack of high quality training data
I don’t completely agree with this. Recent papers have been working miracles with synthetic data generation and smaller datasets (eg, Phi).
Meanwhile, there’s a lot of speculation that Llama4 failed because Meta’s ‘real’ data was vast but not ‘smart,’ with hints via lines like this:
In order to maximize performance, we had to prune 95% of the SFT data, as opposed to 50% for smaller models, to achieve the necessary focus on quality and efficiency.
Whereas Deepseek, with a very similar architecture and size, wrote about how well synthetic data worked in their GRPO paper.
And this keeps happening. As an example, Kimi Linear is (subjectively) performing very well in spite of its ‘small’ training dataset: https://huggingface.co/moonshotai/Kimi-Linear-48B-A3B-Instruct
IMO the limiting factor seems to be GPU time, dev time, and willingness to ‘experiment’ with exotic architectures, optimizations, and more specialized models (including the burnt time/cash on experiments that don’t work).






Never knew this was a thing. Super cool, and how it should be; detached from the actual car.
Still, I’d be more interested in safety features, like blind spot detection, hazard highlighting, or prebraking + beeping for potential accidents, than cruise control.
