Practical guide to multimodal embedding and reranker models that extend traditional RAG pipelines to handle text, images, and other modalities in a shared embedding space. Covers model loading, encoding mixed-modality inputs, and computing cross-modal similarities with concrete code examples and performance considerations.

A curated directory of production-ready open-source AI tools and libraries organized by category (core frameworks, models, inference, agents, RAG, training, deployment, benchmarks, safety). Highlights practical CLI tools like PR-Agent, Gemini CLI, LLM, and Repomix that directly integrate AI into developer workflows.
