ELECTRA vs GPT-4

ELECTRA for TensorFlow2, available on NVIDIA NGC, represents a breakthrough in pre-training language representation for Natural Language Processing (NLP) tasks. By efficiently learning an encoder that classifies token replacements accurately, ELECTRA surpasses existing methods within the same computational budget across various NLP applications. Developed on the basis of a research paper, this model benefits significantly from the optimizations provided by NVIDIA, such as mixed precision arithmetic and Tensor Core utilizations onboard Volta, Turing, and NVIDIA Ampere GPU architectures. It not only achieves faster training times but also ensures state-of-the-art accuracy.

Understanding the architecture, ELECTRA differs from conventional models like BERT by introducing a generator-discriminator framework that identifies token replacements more efficiently—an approach inspired by generative adversarial networks (GANs). This implementation is user-friendly, offering scripts for data download, preprocessing, training, benchmarking, and inference, making it easier for researchers to work with custom datasets and fine-tune on tasks including question answering.

GPT-4 is the latest milestone in OpenAI’s effort in scaling up deep learning.

GPT-4 is a large multimodal model (accepting image and text inputs, emitting text outputs) that, while less capable than humans in many real-world scenarios, exhibits human-level performance on various professional and academic benchmarks. For example, it passes a simulated bar exam with a score around the top 10% of test takers; in contrast, GPT-3.5’s score was around the bottom 10%. We’ve spent 6 months iteratively aligning GPT-4 using lessons from our adversarial testing program as well as ChatGPT, resulting in our best-ever results (though far from perfect) on factuality, steerability, and refusing to go outside of guardrails.

GPT-4 is more creative and collaborative than ever before. It can generate, edit, and iterate with users on creative and technical writing tasks, such as composing songs, writing screenplays, or learning a user’s writing style.
