Advanced LoRA Techniques: Multi-LoRA, LoRA+, and Beyond

Last year, I fine-tuned a 7B parameter model with standard LoRA. It worked, but accuracy was 5% lower than full fine-tuning. After experimenting with Multi-LoRA, LoRA+, and advanced techniques, I’ve achieved 98% of full fine-tuning performance with 1% of the parameters. Here’s everything you need to know about advanced LoRA techniques. Figure 1: LoRA Techniques […]

LangGraph Unleashed: Building Stateful Multi-Agent AI Systems with Graph-Based Workflows

Introduction: LangGraph represents a paradigm shift in how we build AI agents. While LangChain excels at linear chains and simple agent loops, LangGraph introduces a graph-based approach that enables complex, stateful, multi-actor applications with cycles, branching, and human-in-the-loop interactions. Released by LangChain Inc. in early 2024, LangGraph has quickly become the go-to framework for building […]

Production RAG Architecture: Building Scalable Vector Search Systems

Three months into production, our RAG system started failing at 2AM. Not gracefully—complete outages. The problem wasn’t the models or the embeddings. It was the architecture. After rebuilding it twice, here’s what I learned about building RAG systems that actually work in production. Figure 1: Production RAG Architecture Overview The Night Everything Broke It was […]

Tool Use and Function Calling: Extending LLM Capabilities with External Actions

Introduction: Function calling transforms LLMs from text generators into action-taking agents. Instead of just producing text responses, models can now decide when to call external functions, APIs, or tools to accomplish tasks. This capability enables building assistants that can search the web, query databases, send emails, execute code, and interact with any system that exposes […]
