This article reviews the breakthrough image‑generation capabilities of GPT‑4o, showcases diverse examples, and offers a detailed speculation on its underlying autoregressive architecture, tokenization methods, VQ‑VAE/GAN advances, and training strategies that could explain its performance.
GLM introduces a unified pretraining framework that combines autoregressive blank‑filling with 2D positional encoding and span‑shuffle, achieving superior performance over BERT, T5 and GPT on a range of NLU and generation tasks such as SuperGLUE, text‑filling, and language modeling.
The article critically examines GPT‑4 and similar transformer models, highlighting persistent hallucinations, outdated knowledge, insufficient domain coverage, lack of planning and memory, and proposes architectural extensions inspired by fast‑slow thinking and differentiable modules to overcome these fundamental constraints.
