1. Tutorial Introduction

UserLM-8b is a user behavior simulation model released by Microsoft in October 2025. Unlike typical LLMs that play the role of "assistant" in conversations, UserLM-8b is used to simulate the "user" role in conversations (based on the WildChat conversation corpus training) and can be used to evaluate the capabilities of large-scale assistants. This model is not a common large-scale assistant and cannot simulate more realistic conversations or solve problems, but it can help develop more powerful assistants. The relevant paper results are "Flipping the Dialogue: Training and Evaluating User Language Models".

The computing resources used in this tutorial are dual RTX 5090 cards.

2. Effect Examples

3. Operation steps

1. Start the container

2. After entering the webpage, you can start a conversation with the model

If "Bad Gateway" is displayed, it means the model is initializing. Since the model is large, please wait about 2-3 minutes and refresh the page.
