fastchat vs GPT-4

The lmsys/fastchat-t5-3b-v1.0 model, hosted on the Hugging Face platform, is a cutting-edge artificial intelligence solution designed to elevate chatbot interactions to new heights of fluency and coherence. This model is created by utilizing the power of Flan-T5 with a staggering 3 billion parameters, fine-tuned on conversations sourced from ShareGPT. Not only does it provide an impeccable foundation for developing dynamic and responsive chatbots for commercial applications, but it is also a vital resource for researchers delving into the intricacies of natural language processing and machine learning. Developed in April 2023 by the FastChat team, led by Dacheng Li, Lianmin Zheng, and Hao Zhang, this model achieves unparalleled language understanding and generation capabilities by implementing an encoder-decoder transformer architecture.

It has been meticulously trained on a dataset of 70,000 conversations, ensuring a broad understanding of various prompts and queries. The model has undergone rigorous testing, including a preliminary evaluation with GPT-4, showcasing its potential to provide informative and conversationally relevant responses. Due to its open-source status under the Apache 2.0 License, the model invites collaboration and innovation, making it a beacon for open science and AI democratization.

GPT-4 is the latest milestone in OpenAI’s effort in scaling up deep learning.

GPT-4 is a large multimodal model (accepting image and text inputs, emitting text outputs) that, while less capable than humans in many real-world scenarios, exhibits human-level performance on various professional and academic benchmarks. For example, it passes a simulated bar exam with a score around the top 10% of test takers; in contrast, GPT-3.5’s score was around the bottom 10%. We’ve spent 6 months iteratively aligning GPT-4 using lessons from our adversarial testing program as well as ChatGPT, resulting in our best-ever results (though far from perfect) on factuality, steerability, and refusing to go outside of guardrails.

GPT-4 is more creative and collaborative than ever before. It can generate, edit, and iterate with users on creative and technical writing tasks, such as composing songs, writing screenplays, or learning a user’s writing style.
