AVAILABLE NOW

One platform.
Four layers.

  1. 01Patented compression algorithms, including dual sparsity and quantization
  2. 02A custom toolchain to compile models: Compress, Compile, Simulate, Deploy; now featuring femto Studio™
  3. 03Purpose-built silicon that executes compressed models natively
  4. 04An open developer platform and robust community supporting it all

So any developer gets 10X lower power and 10X smaller memory, without sacrificing accuracy, across embedded AI, physical AI, and large-model AI.

WHAT CUSTOMERS SAY

In their words.

Our partnership with femtoAI has been instrumental in bringing Legato Frames to life. The combination of innovative audio algorithms, low-power technology, and amazing developer support helped us deliver SpeechSense™ AI in a compact glasses form factor. Additionally, the open developer platform makes it easy for us to stay laser-focused on great user experience, with the ability to use its tools and algorithms or build our own based on our unique needs. We have loved working with the femtoAI team and are excited to continue building together.
