ALBERT vs GPT-4

ALBERT, short for "A Lite BERT," is an optimized version of the widely-used BERT model for natural language processing tasks. Presented in the arXiv paper by Zhenzhong Lan and colleagues, ALBERT offers two parameter-reduction techniques that significantly decrease memory consumption and increase the training speed of BERT without sacrificing performance.

This advancement addresses the challenge of GPU/TPU memory limitations and the typically lengthy training times associated with increasing model sizes. The paper demonstrates through empirical evidence that ALBERT not only performs better than BERT on a variety of benchmarks, like GLUE, RACE, and SQuAD, but it also achieves state-of-the-art results with a smaller parameter count. The research further introduces a self-supervised loss function that enhances the model’s ability to understand inter-sentence coherence, leading to a substantial improvement on tasks requiring multi-sentence inputs. The authors provide the code and pretrained models for ALBERT, making them accessible for widespread use in the NLP community.

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.
