This app is hosted via Streamlit Community Cloud, here
This project uses poetry for dependency management to be consistent with Streamlit Community Cloud's deployment process.
Install poetry with:
pip install -U pip && pip install -U poetryThen, install the project's dependencies in a virtual environment using poetry.
Run:
poetry installYou will need to set all required secrets, which require their own respective accounts. Make a copy of "template.secrets.toml" and rename it to "secrets.toml" in the root of the project. Fill out each field in the file.

| Langchain | https://smith.langchain.com/ |
| OpenAI | https://platform.openai.com/api-keys |
You can then start the development server with hot reloading by running:
poetry run streamlit run ./freestream/🏡_Home.pyI originally created this project as a chatbot for law and medical professionals, but I quickly realized a more flexible system would benefit everyone.
Related to extending the capabilities of generative AI.
| Concept | Definition |
|---|---|
| Large Language Model | A model that can generate text. |
| RAG | Retrieval Augmented Generation |
| C-RAG | Corrective-Retrieval Augmented Generation |
| Self-RAG | Self-reflective Retrieval Augmented Generation |
| ColBERT | Efficient BERT-Based Document Search |
| RAPTOR | Recursive Abstractive Processing for Tree-Organized Retrieval |
FreeStream has two chatbots where you can interact with an LLM of your choosing, for example, GPT-4o or Claude Opus. You can very easily add more LLMs to the chatbot dictionary, like Llama 3 via Ollama, or Gemini-Pro through LangChain's ChatGoogleGenerativeAI. The original chatbot for this project was "RAGbot," which allows you to ask questions about your upload file(s). Curie, is a more for programming and self-learning purposes.
The application MUST...
- Provide a user interface for chatting with large language models.
- Have a retrieval augmented generative chatbot.
- Provide a range of chatbot pages, differentiated by their prompt engineering.
- Let the user "drop-in" their choice of LLM at any time during a conversation.
Allow users to perform image upscaling (PDF, JPEG, PNG) without limits.
The application SHOULD...
- Aim for 24/7 availability.
- Prioritize ease of navigation
- Feature a visually appealing, seamless interface.
