GLaM

LLMs Explained,
GLaM

GLaM, Generalist Language Model, is a trillion-weight model introduced by Google. It achieves competitive performance on multiple few-shot learning tasks. Its performance is comparable to GPT-3. It has significantly improved learning efficiency across 29 public NLP benchmarks in seven categories. Based on the Transformer architecture, the model is pre-trained on a large corpus of text data using unsupervised learning. This pre-training enables the model to learn natural language patterns and structures, which it can then apply to various downstream tasks.

An Overview of GLaM

GLaM is a mixture of experts model, a model that can be thought of as having different submodels, each specialized for different inputs.

GLaM is approximately 7x larger than GPT-3

1.2 Trillion Parameters

The largest GLaM has 1.2 trillion parameters, and it is approximately 7x larger than GPT-3.

Less training cost, less energy consumption

Relatively Energy Efficient

GLaM consumes only 1/3 of the energy used to train the GPT-3 model and requires half of the computation flops for inference.

Better performance with less computation

Excelled in 29 NLP tasks

The model achieves better overall zero, one, and few-shot performance across 29 NLP tasks.
