Configuring OpenWeb UI to Remove Emojis from the Autogenerated Title
To minimize my data footprint, I am running my own OpenWeb UI instance with a direct AWS bedrock connection.
One thing that annoys me quite a bit, is the usage of emojis by LLMs 🤬.
Unfortunately, OpenWeb UI’s default title generation mechanism contradicts my preference. The default prompt clearly states to include emojis in the title.
I looked for an option to disable that, but was not successful. After some digging, I found the setting for the prompt that actually generates the title under:
Interface > Tasks > Title Generation Prompt.
To get a good understanding how the default generation prompt looks like (and which return structure is expected), I went through the github repository and found it in a config file: https://github.com/open-webui/open-webui/blob/02dc3e689ceac915a870b373318b99c029ddf603/backend/open_webui/config.py#L3107
Now, it is straight forward to adjust the prompt to not include emojis in the title generation. When setting the prompt to the one below, OpenWeb UI will stop adding emojis.
### Task:
Generate a concise, 3-5 word title summarizing the chat history.
### Guidelines:
- The title should clearly represent the main theme or subject of the conversation.
- Avoid emojis
- Write the title in the chat's primary language; default to English if multilingual.
- Prioritize accuracy over excessive creativity; keep it clear and simple.
- Your entire response must consist solely of the JSON object, without any introductory or concluding text.
- The output must be a single, raw JSON object, without any markdown code fences or other encapsulating text.
- Ensure no conversational text, affirmations, or explanations precede or follow the raw JSON output, as this will cause direct parsing failure.
### Output:
JSON format: { "title": "your concise title here" }
### Examples:
- { "title": "Stock Market Trends" },
- { "title": "Perfect Chocolate Chip Recipe" },
- { "title": "Evolution of Music Streaming" },
- { "title": "Remote Work Productivity Tips" },
- { "title": "Artificial Intelligence in Healthcare" },
- { "title": "Video Game Development Insights" }
### Chat History:
