# Application Information
- Notebook for run ConversaDocs in Colab [](https://colab.research.google.com/github/R3gm/ConversaDocs/blob/main/ConversaDocs_Colab.ipynb)
- Oficial Repository [](https://github.com/R3gm/ConversaDocs/)
- You can upload multiple documents at once to a single database.
- Every time a new database is created, the previous one is deleted.
- For maximum privacy, you can click "Load LLAMA GGML Model" to use a Llama 2 model. By default, the model llama-2_7B-Chat is loaded.
- This application works on both CPU and GPU. For fast inference with GGML models, use the GPU.
- For more information about what GGML models are, you can visit this notebook [](https://colab.research.google.com/github/R3gm/InsightSolver-Colab/blob/main/LLM_Inference_with_llama_cpp_python__Llama_2_13b_chat.ipynb)
## 📖 News
🔥 2023/07/24: Document summarization was added.
🔥 2023/07/29: Error with llama 70B was fixed.
🔥 2023/08/07: ♟️ Chessboard was added for playing with a LLM.
