Must also install 🤗Transformers, Datasets, Accelerate, sentencepiece, and fire.; Hardware requirements for a specific model can vary; refer to the provided table for minimum RAM sizes for different models.. - Tags unique to FastEdit: bloom, chatbots, falcon, large-language-models. - When rapid iterations on language model edits are necessary, such as testing and tuning with tight feedback loops. ## When NOT to use generative_ai_with_langchain - - If you are seeking a toolkit that does not deeply integrate with Python or requires less dependency on specific frameworks like LangChain. - - When your project specifically avoids the use of advanced agent implementations or you prefer more generalized LLM application development strategies without heavy reliance on LangGraph. ## When NOT to use FastEdit - If your workflow requires integration with TensorFlow instead of PyTorch, since FastEdit is built on top of PyTorch. - For hardware configurations that cannot meet the fast editing mode's requirements; for instance, if you have less than 24GB RAM available. - If rapid edits within seconds are not a priority and longer processing times can be tolerated. ## Common questions ### What is the difference between generative_ai_with_langchain and FastEdit? generative_ai_with_langchain: Build production-ready LLM applications and advanced agents using Python, LangChain, and LangGraph.
