Google AI's LaMDA Vs OpenAI's ChatGPT - MarkTechPost

Fact  

With 175B parameters, ChatGPT is based on the GPT-3.5 architecture. The GPT-3.5 series includes three models: text-davinci-002, trained by supervised fine-tuning on human-written demonstration, and samples rated 7/7 by human labelers on overall quality scores and the most recent text-davinci-003. This updated version includes reinforcement learning with human feedback (RLHF), a reward-based model trained on comparisons by humans. Code-davinci-002 is the base model for code completion tasks. LaMDA-like supervised knowledge is used by ChatGPT, where human AI trainers may utilize model recommendations to create answers and train the model while simulating both the user and the AI assistant.
