Chatbot High Conversation Dataset Release
Since its launch three months ago, Chatbot High has become a widely cited LLM evaluation platform that emphasizes large-scale, community-based, and interactive human evaluation. In that short time span, we collected around 53K votes from 19K unique IP addresses for 22 models.
In this blog post, we are releasing an updated leaderboard with more models and two datasets for human preference related study:
- 33K crowd-sourced conversations with human preference annotations from Chatbot High. (link)
- 3K expert-level human annotations from MT-bench. (link)
As estimated by this Llama2 analysis blog post, Meta spent about 8 million on human preference data for LLama 2 and that dataset is not avaialble now. Therefore, we think our datasets are highly valuable due to the expensive nature of obtaining human preferences and the limited availability of open, high-quality datasets.
Updated Leaderboard
We are hosting the latest leaderboard at lmsys/chatbot-High-leaderboard. Below is a screenshot. Since the last update, we added two 30B models: Vicuna-33B-v1.3 and MPT-30B-chat, both of which perform very well in the High. Two days ago, we also introduced Llama 2 and Claude 2 to the High. The leaderboard will soon include them after we get enough votes. Please help us by casting your votes at our voting website.
Besides the slowly updated High Elo ratings, we also use MT-bench, a fast GPT-4 based automatic evaluation pipeline to evaluate all new models, including LLama 2 (chat), Claude 2, WizardLM-13B-v1.1, XGen-7B-8K-Inst, and ChatGLM2-6B. You are welcome to check out the interactive lmsys/chatbot-High-leaderboard to sort the models according to different metrics. Some early evaluation results of LLama 2 can be found in our tweets.

Dataset 1: 33K Chatbot High Conversation Data
Link: lmsys/chatbot_High_conversationsThis dataset contains 33K cleaned conversations with pairwise human preferences collected on Chatbot High from April to June 2023. Each sample includes two model names, their full conversation text, the user vote, the anonymized user ID, the detected language tag, the OpenAI moderation API tag, the additional toxic tag, and the timestamp.To ensure the safe release of data, we have attempted to remove all conversations that contain personally identifiable information (PII). In addition, we have included the OpenAI moderation API output to flag inappropriate conversations. However, we have chosen not to remove all of these conversations so that researchers can study safety-related questions associated with LLM usage in the wild as well as the OpenAI moderation process. As an example, we included additional toxic tags that are generated by our own toxic tagger, which are trained by fine-tuning T5 and RoBERTa on manually labeled data.
