Chat Basics

The chat interface represents the core interaction method for engaging with AI models within Open WebUI. Let's walk through the essential functions to get you started effectively.

Step 1: Start a New Chat

Every new task begins with a new chat:

  1. Click the "+ New Chat" button in the left sidebar
  2. The main window will clear and be ready for your input
  3. Your previous conversations remain safely stored in the chat history list for continuation or reference

Step 2: Select the Right Model (The Most Important Step!)

Before typing your first message, you must select which AI model to use. This depends on your data confidentiality requirements and intended use.

  1. Click the "Select Model" button directly above the input field
  2. A list of available models will appear. For beginning users, we recommend using the standard base models
  3. Choose the appropriate model, such as "C-KIT-Standard-Chat" for general inquiries with non-sensitive data

Step 3: Ask Your First Prompt

Type your question or instruction into the input field at the bottom of the screen. Alternatively, click the microphone icon in the input field to dictate your question. Press Enter or click the send arrow.

Example Prompt: 

Explain the principles of machine learning in three main points.

The AI will process your request and generate a response in the chat window. You can continue the dialogue by asking further questions, with the conversation context maintained throughout.

More Than Text: Using Interactive Tools

Below the input field, you'll find additional tools that expand the AI's capabilities. These may be available depending on your selected model:

  • Web Search: Access current internet information for questions about recent events or specific topics
  • Image Generation: Create images based on text descriptions
  • Code Interpreter: Execute code for data analysis, complex calculations, or chart creation

Voice Input: For those who prefer speaking to typing, the microphone icon activates voice recognition for natural question dictation.

Managing Chat Histories

As you use the platform regularly, your chat history will grow. Open WebUI provides simple tools to stay organized:

  • Rename Chats: Hover over a chat title in the left sidebar, click the three dots (...), and select the pencil icon to give it a descriptive name
  • Delete Chats: Select the trash icon to remove conversations you no longer need
  • Access Previous Chats: Simply click on any chat title in the history list to load and continue that conversation

Temporary Chat: Conversations Without Saving

Sometimes you might want to ask a quick question without saving the conversation to your history:

  1. Start a new chat
  2. Click the speech bubble icon in the top right of the chat window to activate "Temporary Chat"
  3. This chat will not be saved in your history and will be discarded after closing the window

Advanced Options: Chat Parameters

For experienced users, additional settings are available in the top right of the chat window (settings/slider icon):

  • Temperature: Controls response creativity (Values 0-1)
  • Low temperature (e.g., 0.2): Focused, factual responses - good for summaries
  • High temperature (e.g., 0.9): Creative, varied responses - good for brainstorming

For normal use, you can leave these settings at their default values.

Tips for Effective Chat Interactions

  • Start with clear, specific prompts that articulate exactly what you need
  • Provide relevant context when your questions involve specific situations
  • Choose models appropriately based on information sensitivity and nature
  • Organize conversations with meaningful names that reflect their content
  • Save important discussions for future reference

The chat interface balances simplicity with sophistication, offering intuitive interaction for newcomers while providing advanced options for experienced users seeking precise control over their AI interactions.
