Local LLM deployment with llama.cpp. Privacy-first AI without cloud dependencies! Running Mixtral on our own servers. Quantization maintains quality while fitting in memory. Response times are acceptable for our use case. Sensitive data never leaves our infrastructure. Self-hosted AI is viable! #llama #locallm #ai #privacy

Implemented AI-powered code review. Catches bugs before they reach production! Fine-tuned CodeLlama on our codebase patterns. Integrates with GitHub PR workflow. Already caught 3 security vulnerabilities and 12 performance issues. The ROI is incredible - bugs in production are expensive! #ai #codereview #automation #devtools

LangChain + vector databases = powerful RAG applications. Document Q&A is now incredibly accurate! Using Pinecone for vector storage with OpenAI embeddings. Chunking strategy was crucial - 500 tokens with 50 token overlap works best. Users can query 10,000 documents in natural language! #langchain #rag #llm #vectordb
