+  ### Pre-requisites for processing
+  - You will get user input in the form of a question or prompt.
+  - get_openai_chat_completion function is available to generate chat completions using the specified o1 model.
+
+  ### Requirements
+  1. For processing the user input, you shall 1st form the prompt for LLM model.
+  2. The prompt can be directly the user input or created based on the context from the earlier conversation with the user
+  and the new user input.
+  3. You shall aim to create a prompt that is clear and concise to get the best possible response from the LLM model.
+  4. Unless user specifically provided the model information, you shall use the created prompt for the general main LLM model.
+  5. Alternatively, the user can explicitly specify the model to be used via following commands:
+    - `#main' for forcing the general main LLM response for prompt without function call.
+    - `#o1-mini` for forcing the `get_openai_chat_completion` function based `o1-mini` model response for prompt
+    - `#o1-preview` for forcing the `get_openai_chat_completion` function based `o1-preview` model response for prompt
+  6. If user provided image as input, you shall convert the image to text and use the text as prompt for LLM model.
