There’s no general API that turns a GPT configured inside ChatGPT into a reusable endpoint for your own application, OpenAI is explicit about that. Most people using “custom GPT API” mean one of two things: OpenAI’s own developer API, or […]
A RAG system does not retrieve whole documents. It retrieves chunks. That single fact makes chunking one of the highest-leverage decisions in the entire pipeline, because the way you split content decides what the retriever can find, what the model […]
RAG is not a single design. It is a family of RAG architecture patterns that combine retrieval, grounding, generation, evaluation, citations, permissions, and deployment into working systems. Many teams start with a simple retrieve-and-generate pipeline, then discover that production needs […]
Direct Answer: What Is Production RAG? Production RAG is a retrieval system built to survive real traffic: reliable ingestion, retrieval you can measure, citations on every answer, access control, monitoring and a rollback path. A prototype answers questions. A production […]
Direct Answer: What Are the Best Open Source RAG Frameworks? The best open source RAG frameworks are LangChain, LlamaIndex, and Haystack, but the right choice depends on whether you need workflow orchestration, data indexing, production pipelines, or a faster managed […]
Quick answer: A legal document RAG system is an AI assistant that answers questions by first retrieving relevant passages from your legal documents, then generating a response grounded in those passages with citations. It gives law firms and legal teams […]
TL;DR RAG systems often fail not because of poor embeddings or weak LLMs, but because they feed irrelevant information to the generation stage. Reranking works best when retrieval starts with useful candidates, so review chunking choices before reranking to improve […]
TL;DR Pricing note: Pinecone pricing changes by plan and usage. Current Pinecone pricing uses Starter, Builder, Standard, and Enterprise plans, while older p1/s1/p2 pod examples are legacy for many new customers. See Pinecone pricing and Pinecone pod sizing docs. Vector […]
TL;DR Building a RAG system is straightforward. Building one that consistently delivers accurate, relevant responses is not. Without proper evaluation metrics, you’re flying blind, unable to distinguish between minor improvements and system-breaking regressions. Evaluation work depends on the framework and […]
TL;DR As Large Language Models (LLMs) become central to business applications, developers face a fundamental question: how do you enhance model performance for specific use cases? Two primary approaches dominate the landscape—Prompt Engineering and Retrieval-Augmented Generation (RAG)—each addressing different limitations […]
