UltraChat is a large-scale dataset of 1.57M informative, diverse multi-round dialogue instructions generated with LLMs, plus UltraLM, a series of chat models fine-tuned on it. It is primarily a research dataset for training open-source instruction-following chat models.

Use cases

• download multi-round chat instruction data for fine-tuning an LLM
• train an instruction-following chatbot with SFT
• find open dialogue datasets for supervised fine-tuning
• reproduce open-source chat models like UltraLM
• get instruction tuning data as an alternative to ShareGPT

When to choose

• you need large-scale multi-round instruction data for supervised fine-tuning
• you want a permissively licensed (MIT) chat dataset for LLM research
• you want a proven dataset behind top AlpacaEval open models

When to avoid

• you need preference/RLHF data rather than SFT dialogues (use UltraFeedback instead)
• you want a production chatbot application rather than training data
• you need human-written rather than model-generated dialogues
