Efficiency from Sparsity

By pruning neural networks to only store and process the necessary components, we reduce power consumption by 100x and memory footprint by 10x — all with minimal effect on performance.

Making Neural Networks Sparse

Neural networks start out dense

Every node connected to every other.

As they learn, weak connections fade

This is just like the human brain pruning unused synapses.

What remains is a sparse, efficient network

Focused, mature, and powerful.

Math Under the Hood

In math, multiplying or adding zero has no effect.

So why spend time, energy, and silicon computing it?

femtoAI is built on this simple insight:
Skip zero, and only do the work that matters.

From Math to Silicon

femtoAI turns sparsity into a hardware advantage.

Only non-zero weights are stored.
Only non-zero weights and activations are computed.

The result: 100x lower power, 10x model capacity.

Sparsity in Action

femtoAI’s sparsity-first design consumes significantly less power by activating only the neurons that matter.
