+- **Model**: The chat model to use.
   - Ensure you set the chat model correctly on the **Model providers** page.
   - You can use different models for different components to increase flexibility or improve overall performance.
-- **Creativity**: A shortcut to **Temperature**, **Top P**, **Presence penalty**, and **Frequency penalty** settings, indicating the freedom level of the model. From **Improvise**, **Precise**, to **Balance**, each preset configuration corresponds to a unique combination of **Temperature**, **Top P**, **Presence penalty**, and **Frequency penalty**.

From **Improvise**, **Precise**, to **Balance**, each preset configuration corresponds to a unique combination of **Temperature**, **Top P**, **Presence penalty**, and **Frequency penalty**.
   This parameter has three options:
   - **Improvise**: Produces more creative responses.
   - **Precise**: (Default) Produces more conservative responses.
   - **Balance**: A middle ground between **Improvise** and **Precise**.
-- **Temperature**: The randomness level of the model's output.  
+- **Temperature**: The randomness level of the model's output.
   Defaults to 0.1.
   - Lower values lead to more deterministic and predictable outputs.
   - Higher values lead to more creative and varied outputs.
   - A temperature of zero results in the same output for the same prompt.
-- **Top P**: Nucleus sampling.  
+- **Top P**: Nucleus sampling.
   - Reduces the likelihood of generating repetitive or unnatural text by setting a threshold *P* and restricting the sampling to tokens with a cumulative probability exceeding *P*.
   - Defaults to 0.3.
-- **Presence penalty**: Encourages the model to include a more diverse range of tokens in the response.  
+- **Presence penalty**: Encourages the model to include a more diverse range of tokens in the response.
   - A higher **presence penalty** value results in the model being more likely to generate tokens not yet been included in the generated text.
   - Defaults to 0.4.
-- **Frequency penalty**: Discourages the model from repeating the same words or phrases too frequently in the generated text.  
+- **Frequency penalty**: Discourages the model from repeating the same words or phrases too frequently in the generated text.
   - A higher **frequency penalty** value results in the model being more conservative in its use of repeated tokens.
   - Defaults to 0.7.
-- **Max tokens**:  
+- **Max tokens**:
   This sets the maximum length of the model's output, measured in the number of tokens (words or pieces of words). It is disabled by default, allowing the model to determine the number of tokens in its responses.

-Typically, you use the system prompt to describe the task for the LLM, specify how it should respond, and outline other miscellaneous requirements. We do not plan to elaborate on this topic, as it can be as extensive as prompt engineering.
