via “knowledge synthesis and question answering with broad domain coverage”
OpenAI's flagship model, GPT-4 is a large-scale multimodal language model capable of solving difficult problems with greater accuracy than previous models due to its broader general knowledge and advanced reasoning...
Unique: Trained on 1.76 trillion tokens from diverse internet sources, books, and academic papers, enabling broad domain coverage; uses transformer attention to synthesize knowledge across multiple facts without external retrieval, trading latency for knowledge breadth
vs others: Broader domain knowledge than GPT-3.5 or Claude 2 due to larger training scale; comparable to Claude 3 Opus but with more recent training data (April 2023 vs early 2024); faster than RAG-based systems because knowledge is in parameters, not retrieved
