12 Open Source AI Tools That Feel ILLEGAL To Know About
Are you paying thousands of dollars a month for AI subscriptions when the exact same software is sitting on GitHub for free? Discover 12 open-source AI tools that feel illegal to know about, and learn how to build the ultimate self-hosted, enterprise-grade AI stack for exactly $0.
In this video, Cloud Codes breaks down the exact open-source repositories replacing billion-dollar SaaS companies. We explore how to fix RAG hallucinations with Chonkie and Qdrant, how to run local models with Ollama and vLLM, and how to scrape the web for free using Crawl4AI.
We also dive into the tools serious AI developers use to force LLMs to output valid JSON (Instructor and Outlines), how to manage all your AI API keys in one place (LiteLLM), and how to stop guessing and start mathematically testing your AI apps with DSPy, Langfuse, and Ragas.
