Usage

1. Create a Python virtual environment:

   Using Conda:

    conda create --name <env_name> python=3.10
    conda activate env_name
   

   Using venv:

    python3 -m venv <env_name>
    source env_name/bin/activate
   
    # On Windows use `env_name\Scripts\activate`
   

2. Install required dependencies:

    pip install -r requirements.txt
   

Environment Variables

Before running any script create a .env file and add the API Token keys for the models whichever you want to use.

OPENAI_API_KEY = ""
ANTHROPIC_API_KEY = ""
GOOGLE_API_KEY = ""
HUGGINGFACEHUB_API_TOKEN = ""

Runing Scripts

Each script can be run individually. For example, to run OpenAI ChatModel use:

python Chat_Models/chatmodel_openai.py

Note: Edit the scripts and try with different examples.
