SpeakingAI is a demo of privately deployable 'GPT-4o like AI + RAG', a fully functional web AI server with audio query/answer in streaming, using LLM and RAG for backend knowledge.

🐍 Companion piece to Building Context-aware Question-Answering Systems with LLMs, a step-by-step guide to using embeddings, vector search, and prompt engineering for building context-aware question-answering system

A playbook and Colab-based demo for helping engineering teams adopt Generative AI. Includes a working RAG pipeline using LangChain + Chroma, OpenAI GPT-4o embeddings, prompt engineering best practices, and automated LLM evaluations with Ragas.

In this tutorial, we’ll walk you through the steps to fine-tune an LLM using the Hugging Face transformers library, which provides easy-to-use tools for working with models like GPT, BERT, and others. we’ll also provide a code demo for fine-tuning GPT-2 (a smaller version of GPT-3) on a custom text dataset.
