| How does a Language Model like GPT makes discerning choices regarding which plugins to run? Well, this is done using the Language Model as a reasoning agent and allowing it to assess and process information intelligently.<br><br> | |
| - <b>Langchain & OpenAI Function Calling</b>: AI models like gpt-3.5-turbo-0613 and gpt-4-0613, are designed to identify when and how to activate functions through API calls. These function-specific APIs generate a JSON object with necessary arguments, aiming to surpass the efficacy of traditional chat or text completion APIs.<br><br> | |
| - <b>Gradio Chatbots</b>: Gradio provides super easy way to build Chatbot UI. Refer our <a href="https://gradio.app/docs/#chatbot" target="_blank">Docs</a>. Using Langchain's OpenAI Functions Agent you can create chatbots designed to respond to queries by communicating with external APIs. The API responses are fed back to the Language Model for processing and a new response is generated for the user.The versatility of using Gradio to build LLM applications is immense. FOr example, in this Gradio app, you can have an array of Plugins based on functions which are tailored for various purposes (image, video, audio, text generation, utilities etc). This enhancing the breadth and depth of interactions with your Language Model. | |

| # Guide to add new Plugins | |
| add_plugin_steps = """ | |
| ## Steps to add new Plugins to your Langchain-Gradio ChatGPT PLUGIN WebUI | |
| 1. **Acquire the API Endpoint** | |
| - You need an API which you can query, and for this example let's consider using a The Bored API. | |
| - **API Endpoint**: [https://www.boredapi.com/api/activity/?type=](https://www.boredapi.com/api/activity/?type=) | |
| 2. **Create a Function to Query the API** | |
| - You can access any Gradio demo as an API via the Gradio Python Client. | |
| ```python | |
| def bored_api(activity_type) -> str: | |
| ''' | |
| Get a random activity to do based on the activity type. | |
| ''' | |
| activity_type_list = ["education", "recreational", "social", "diy", "charity", "cooking", "relaxation", "music", "busywork"] | |
| activity_type = activity_type.lower() | |
| if activity_type not in activity_type_list: | |
| activity_type = random.choice(activity_type_list) | |
| api_url = "https://www.boredapi.com/api/activity/?type=" + activity_type | |
| response = requests.get( | |
| api_url | |
| ) | |
| return response.json()['activity'] | |
| ``` | |
| 3. **Add Function definitions** | |
| - Add the function definition to the `gpt_function_definitions.py` file (simply copy and paste). Don't forget to add function description in docstring. | |
| - Add required imports | |
| ```python | |
| from gpt_function_definitions import generate_image, generate_caption, get_news, bored_api | |
| ``` | |
| 4. **Add the function to the Tools list** | |
| - Add a description - describe what your function does. Models like GPT3.5/4 support Function Calling. The OpenAI Functions Agent from Langchain is designed to work with these functions and models. | |
| - Name - add a name of your function, don't include spaces | |
| ```python | |
| tools = [ | |
| #image generation | |
| ... | |
| # Describe an image | |
| ... | |
| # Get lattest top news | |
| ... | |
| # Bored Api | |
| Tool.from_function( | |
| func=bored_api, | |
| name="bored_api", | |
| description="Get a random activity to do based on the activity type" | |
| # coroutine= ... <- you can specify an async method if desired as well | |
| ), | |
| ] | |
| ``` | |
| 5. **Update the Chatbot Layout** | |
| - Go to the Blocks Chatbot layout and add a new checkbox for your plugin as: | |
| ```python | |
| bored = gr.Checkbox(label="🙄bored", value=False) | |
| ``` | |
| - Add the new checkbox component (example - <i>bored</i>) to your submit and click events for your chatbot and to the predict function accordingly. | |
| - And also to the `plugins` list in `predict` | |
| ```python | |
| plugins = [stable_diff, image_cap, top_news, search, bored] | |
| ``` | |
| **Thats it! you have added your own brand new CHATGPT Plugin for yourself. Go PLAY!!** | |
