How to Build a $300 AI Computer for the GPU-Poor

Read time: 11 minutes

This article demonstrates how software developers can build a powerful $300 AI computer using an AMD-based mini PC. It covers prepping the system with the right drivers and middleware, running large language models like LLaMA 2 on the CPU, and generating images with Stable Diffusion on the integrated AMD GPU. The key is optimizing memory allocation and leveraging open-source tools like llama.cpp to enable generative AI capabilities on a budget-friendly system.

Breaking up is hard to do: Chunking in RAG applications

Read time: 7 minutes

This article explores the importance of "chunking" data when building Retrieval Augmented Generation (RAG) systems. The author discusses various chunking strategies, such as fixed sizes, random chunks, and context-aware chunking, and how they impact the performance of LLM-based applications. The key takeaway is that choosing the right chunking approach is crucial for creating accurate and relevant responses grounded in the source data.

Chunking Strategies for LLM Applications

Read time: 10 minutes

Another article on chunking, this time from Pinecone, explores the importance of "chunking" - breaking down large text into smaller segments - when building applications that leverage Large Language Models (LLMs). It discusses how chunking can optimize the relevance of content retrieved from a vector database, and covers various chunking methods, including fixed-size, sentence-based, and semantic chunking. The article provides guidance on determining the optimal chunk size and method for your specific application needs, such as semantic search, conversational agents, or integrating with LLMs with token limits.

Intro to LLM Agents with Langchain: When RAG is Not Enough

Read time: 15 minutes (+ 1 hour video)

This article provides a detailed introduction to building LLM agents using Langchain, a platform for productionizing LLM applications. It covers key agent architecture components like planning, memory, and tools, demonstrating how to leverage techniques like chain of thought, self-consistency, and custom tools. The author showcases how to construct a complete agent that can solve tasks like searching for information and generating CSV files, highlighting the importance of integrating all architectural elements for effective agent performance.

Retrieval Augmented Generation (RAG) from Scratch

Read time: 20 minutes (Jupyter notebook)

This tutorial walks through building a Retrieval Augmented Generation (RAG) system from scratch using Python and the Hugging Face Transformers library. RAG is a powerful framework for leveraging large language models and knowledge bases to generate high-quality, fact-based responses. The tutorial covers key concepts like vector databases, retrieval, and integration with a language model, providing a hands-on introduction to this cutting-edge AI technique. It does NOT use Langchain or Llamaindex, so you will come out with a deeper understanding the the mechanics of the system vs using the afore mentioned abstraction frameworks.  Read the full tutorial here.

💰Cost of Self-Hosting Llama-3 8B-Instruct

Read Time: 10 minutes

This article explores the cost of self-hosting the Llama-3 8B-Instruct language model, comparing it to the pricing of ChatGPT. It covers the hardware requirements, implementation challenges, and an unconventional approach of self-hosting the hardware to significantly reduce the cost per 1 million tokens, from $17 with a cloud provider to less than $0.01. However, the article notes that the breakeven point for this approach is around 5.5 years, making it more suitable for high-usage scenarios.
