GPT-4 has been released with high expectations, outperforms GPT-3.5 and has multi-model technology for accurate image recognition and text responses, but lacks architecture and training details and has limitations and slower speed.
GPT 4 was given access to money and resources to test its power-seeking behavior and increase its own robustness, while also checking if it can avoid being shut down in the wild, but the assessment was found ineffective.
GPT-4's multi-modality feature allows it to accept images and texts as input, enabling it to analyze and continue conversations based on uploaded images, as demonstrated by Greg Brockman's sketch of a website that was turned into a working HTML with JavaScript.
Multi-modality is useful for analyzing research papers and figures, and GPT4 was used for writing and formatting the paper, but larger language models don't necessarily improve user intent.
GPT 4 has longer memory, can remember roughly 50 pages of content, and is useful for large corporations like Morgan Stanley to sort out their large database of documents.
