    Assemble tasks to build an E2E application with everyday language.
    <br>There are 2 types of tasks.
    <br>
    <br>**AI Task**: Ask ChatGPT to do something for you. Eg, summarize a text.
    <br>**Code Task**: ChatGPT will create a python function to do something for you. Eg, get the text from a website.
    <br> Use this task for things that ChatGPT can't do on its own, like access the internet or iterate over 4K+ tokens.
    <br>
    <br>Output from previous tasks can be referenced in subsequen tasks with {tn}. Max 10 tasks allowed (for now).
