If you don’t have an OpenAI API key yet, this article,A Beginner’s Guide to the OpenAI API, is for you! Because we will be using the LangChain framework, we will also load the actualgptmodel from thelangchainlibrary: fromlangchain.llms.openaiimportOpenAI llm=OpenAI(model_name="gpt-...
we will delve into the theory and provide a step-by-step code implementation to help you create your own miniGPT model. The final code is only 400 lines and works on both CPUs as well as on the GPUs. If you want to jump to the implementation...
https://www.youtube.com/watch?v=9vM4p9NN0Ts本讲座简要概述了构建类似 ChatGPT 的模型,涵盖预训练(语言建模)和后训练(SFT/RLHF)。对于每个组件,它探索了数据收集、算法和评估方法方面的常见做法。本次客座讲座由 Yann Dubois 在 2024 年夏季的斯坦福大学 CS229:机

OpenAI has started building ChatGPT 5 — its next-generation AI model GPT-5. CEO Sam Altman confirmed this in a recent interview, and claimed it could possess superintelligence, but the company would need further investment from its long-time partner Microsoft to make it a r...
Llama was trained on 70 billion parameters, and while OpenAI hasn’t released its parameters for GPT-4, they’re estimated to be around 1.5 trillion. Related: Nvidia drops new AI chip expected to cut development costs The sources said Meta anticipates training for the large language model (LL...
PPT-style large models can seve a variety of industries, but have numerous vulnerabilities when applied commercially "In my opinion, whether ChatGPT can truly develop in this AI 2.0 wave depends on whether it has a business model and whether customers are willing to pay. No matter how we tra...
