Researchers discovered that within every large model, there is a "winning ticket" - a small subnetwork that performs the main work.
They proved that if you find it and reset it to its initial state, it will work just like the entire large model.
But there was a nuance that immediately killed its practical application...
to find this "ticket", you first need to train the full model. no one wanted to train the model twice for a single deployment. it looked cool in academia, but it was useless in production.
The original 2018 article was truly impressive.
But today, after 8 years... we've finally achieved a breakthrough at the hardware level: structured sparsity
Modern GPUs (NVIDIA Ampere and newer) no longer just "emulate" pruning.
They have native support for block sparsity (2:4 patterns), built directly into the hardware.
This isn't theory - it's silicon-level acceleration.
The math looks very convincing: a network with 90% sparsity = 50% less memory bandwidth + 2× computing bandwidth. Real acceleration without losing accuracy.
Three factors made this ready for production in 2026:
- training with sparsity in mind (the model is initially trained sparse)
- native support in PyTorch 2.0 and Apple Neural Engine
- understanding that AI models are inherently 90% redundant
Evolution complicates systems. We've finally learned to "thin out" them.
The era of bloated and inefficient models is officially over. Tools have finally caught up with theory, and those who stop paying for 90% of the weights they don't need will win.
Future of AI is more compact, faster, and more efficient models.
