Neuron
A software development kit provided by AWS for Inferentia and Trainium chips, including a compiler, runtime and libraries, and supporting deployment of models from mainstream frameworks.

During the porting process, the Deepgram team verified the numerical correctness and performance of Nova-3's custom operators on Neuron one by one, and implemented fallback for some operators through Neuron's custom operator interface.
Deepgram engineers found that audio feature extraction and attention computation are the main performance hotspots of Neuron kernels on speech models.
When the hardware does not support native low-precision tensor cores, int4 weights are unpacked and expanded to bf16 or fp16 before matrix multiplication, causing the bandwidth and capacity advantages to be lost; T4G widening int4 to 16 bits and Neuron widening int4 to bf16 both fall under this mechanism.
A study published in Neuron showed that when sufficient glucose is present in the brain, neurons tune to environmental information with greater precision.
