LLM-100-Lessons: A Comprehensive Knowledge Base on Large Language Models and AI Agent Technologies

LLM and AI Agent technologies are reshaping the paradigm of AI applications, but the field has rapid technical iterations and a steep learning curve. The LLM-100-Lessons project builds a systematic and structured knowledge base that comprehensively covers over 100 core topics from pre-training, fine-tuning, inference optimization to Agent architecture design, providing a complete learning roadmap for developers, researchers, and technical decision-makers while balancing accuracy and readability.

LLM and AI Agent technologies are developing rapidly, with new concepts and methods emerging constantly. Fragmented blogs or paper abstracts make it difficult for practitioners to establish a complete understanding of the technical system, leading to a steep learning curve. The LLM-100-Lessons project was born to address this issue.

The knowledge base covers six major modules:

1. Pre-training and Foundation Models: Evolution of Transformer architecture, pre-training objectives, large-scale training engineering, data preparation;
2. Model Fine-tuning and Adaptation: Full-parameter fine-tuning, PEFT (LoRA/Adapter/Prefix Tuning/QLoRA), instruction fine-tuning, RLHF and alignment technologies;
3. Inference Optimization and Deployment: Quantization techniques, inference acceleration frameworks, speculative decoding and caching strategies;
4. RAG and Knowledge Enhancement: Document processing pipeline, vector databases and retrieval, RAG architecture patterns;
5. AI Agent System Architecture: Core components (planning/memory/tool use/reflection), mainstream frameworks, multi-Agent systems;
6. Evaluation and Monitoring: Model capability evaluation, production system monitoring.

The knowledge base features comprehensive coverage (end-to-end technical closed loop), in-depth organization (each topic balances accuracy and readability), differentiated learning paths (paths for beginners/engineers/researchers), and continuous tracking of cutting-edge trends (model architecture innovation, long-context technology, Agent evolution, multi-modal fusion), which can meet the needs of users with different backgrounds.

LLM-100-Lessons provides a systematic knowledge map for the LLM and Agent field. In the era of rapid technical iterations, structured knowledge organization is particularly valuable. Whether you are a novice or a senior practitioner, you can gain value from it, and the knowledge base will continue to be updated and improved to become an important reference resource in the field.
