Gpt2 perplexity
WebOur largest model, GPT-2, is a 1.5B parameter Transformer that achieves state of the art results on 7 out of 8 tested language modeling datasets in a zero-shot setting but still underfits WebText. Samples from the model reflect these improvements and contain coherent paragraphs of text. WebNov 10, 2024 · GPT-2 reduced the perplexity from 99.8 to 8.6 and improved the accuracy significantly. GPT-2 outperformed 3 out 4 baseline models in reading comprehension tasks in zero shot setting.

WebI've been actively following them since GPT2. I thought GPT2 was pretty funny, though occasionally insightful. I started using GPT3 for work after realizing how powerful it was. I annoyed my friends with how much I talked about it. Then ChatGPT launched and OpenAI became a household name. That process was a whole lot longer than five days.
