Build with Top AI Models for FREE: The New Rules of AI Engineering

Stop paying for AI APIs. The game has changed. In 2025, you can access and build with top-tier, state-of-the-art AI models completely for FREE. What once required massive budgets, PhDs, and months of training can now be prototyped in minutes with a single, free API call. This presentation breaks down the critical shift from traditional Machine Learning Engineering to the new world of AI Engineering—the new rules you need to know to build effectively. This presentation is inspired by the core concepts in the book "AI Engineering" by Chip Huyen. If you want a deeper dive into these topics, I highly recommend checking it out. 🔥 In this guide, you will learn: How to find and use top-ranking AI models like DeepSeek and Qwen3 with zero API costs. The fundamental shift from being a "Model Creator" to a "Model Adapter." The 3 new core skills (Prompting, RAG, Fine-tuning) every developer needs for 2025. A live demo of building a resilient, multi-model backend in under 90 seconds.
