llm-course AI技能包 是 AI Skill Hub 本期精选AI工具之一。在 GitHub 上收获超过 79.3k 颗 Star，综合评分 8.5 分，整体质量较高。我们强烈推荐将其纳入你的 AI 工具库，帮助提升工作效率。
**为什么要使用开源工具而非商业 SaaS？**
对于个人开发者和有隐私需求的用户，本地部署的开源工具意味着数据不离本机，不受第三方服务商的数据政策约束。同时，开源工具通常没有使用次数限制和月度费用，一次安装即可长期使用，对于高频使用场景的总拥有成本（TCO）远低于订阅制商业工具。
**安装与环境准备**
llm-course AI技能包 依赖 Python 运行环境。建议通过 pyenv（Python）或 nvm（Node.js）管理 Python 版本，避免全局环境污染。对于新手用户，推荐先创建虚拟环境（python -m venv venv && source venv/bin/activate），再安装依赖，这样即使出现问题也可以随时删除虚拟环境重新开始，不影响系统稳定性。
**社区与维护**
GitHub Issue 和 Discussion 是获取帮助的最快渠道。在提问前建议先检查 Closed Issues（已关闭的问题），大多数常见问题都已有解答。遇到 Bug 时，提供 pip list 的输出、完整错误堆栈和最小可复现示例，能显著提高开发者响应速度。AI Skill Hub 将持续追踪 llm-course AI技能包 的版本更新，及时通知重要功能变化。

简介
𝕏 Follow me on X • 🤗 Hugging Face • 💻 Blog • 📙 LLM Engineer's Handbook
<a href="https://a.co/d/a2M67rE"><img align="right" width="25%" src="https://i.imgur.com/7iNjEq2.png" alt="LLM Engineer's Handbook Cover"/></a>The LLM course is divided into three parts:
- 🧩 LLM Fundamentals is optional and covers fundamental knowledge about mathematics, Python, and neural networks.
- 🧑🔬 The LLM Scientist focuses on building the best possible LLMs using the latest techniques.
- 👷 The LLM Engineer focuses on creating LLM-based applications and deploying them.
[!NOTE] Based on this course, I co-wrote the LLM Engineer's Handbook, a hands-on book that covers an end-to-end LLM application from design to deployment. The LLM course will always stay free, but you can support my work by purchasing this book.

2. Building a Vector Storage
Creating a vector storage is the first step to building a Retrieval Augmented Generation (RAG) pipeline. Documents are loaded, split, and relevant chunks are used to produce vector representations (embeddings) that are stored for future use during inference.
- Ingesting documents: Document loaders are convenient wrappers that can handle many formats: PDF, JSON, HTML, Markdown, etc. They can also directly retrieve data from some databases and APIs (GitHub, Reddit, Google Drive, etc.).
- Splitting documents: Text splitters break down documents into smaller, semantically meaningful chunks. Instead of splitting text after n characters, it's often better to split by header or recursively, with some additional metadata.
- Embedding models: Embedding models convert text into vector representations. Picking task-specific models significantly improves performance for semantic search and RAG.
- Vector databases: Vector databases (like Chroma, Pinecone, Milvus, FAISS, Annoy, etc.) are designed to store embedding vectors. They enable efficient retrieval of data that is 'most similar' to a query based on vector similarity.

7. Deploying LLMs
Deploying LLMs at scale is an engineering feat that can require multiple clusters of GPUs. In other scenarios, demos and local apps can be achieved with much lower complexity.
- Local deployment: Privacy is an important advantage that open-source LLMs have over private ones. Local LLM servers (LM Studio, Ollama, oobabooga, kobold.cpp, etc.) capitalize on this advantage to power local apps.
- Demo deployment: Frameworks like Gradio and Streamlit are helpful to prototype applications and share demos. You can also easily host them online, for example, using Hugging Face Spaces.
- Server deployment: Deploying LLMs at scale requires cloud (see also SkyPilot) or on-prem infrastructure and often leverages optimized text generation frameworks like TGI, vLLM, etc.
- Edge deployment: In constrained environments, high-performance frameworks like MLC LLM and mnn-llm can deploy LLM in web browsers, Android, and iOS.

5. Preference Alignment
Preference alignment is a second stage in the post-training pipeline, focused on aligning generated answers with human preferences. This stage was designed to tune the tone of LLMs and reduce toxicity and hallucinations. However, it has become increasingly important to also boost their performance and improve their usefulness. Unlike SFT, there are many preference alignment algorithms. Here, we'll focus on the three most important ones: DPO, GRPO, and PPO.
- Rejection sampling: For each prompt, use the trained model to generate multiple responses, and score them to infer chosen/rejected answers. This creates on-policy data, where both responses come from the model being trained, improving alignment stability.
- Direct Preference Optimization Directly optimizes the policy to maximize the likelihood of chosen responses over rejected ones. It doesn't require reward modeling, which makes it more computationally efficient than RL techniques but slightly worse in terms of quality. Great for creating chat models.
- Reward model: Train a reward model with human feedback to predict metrics like human preferences. It can leverage frameworks like TRL, verl, and OpenRLHF for scalable training.
- Reinforcement Learning: RL techniques like GRPO and PPO iteratively update a policy to maximize rewards while staying close to the initial behavior. They can use a reward model or reward functions to score responses. They tend to be computationally expensive and require careful tuning of hyperparameters, including learning rate, batch size, and clip range. Ideal for creating reasoning models.
