According to @AndrewYNg, DeepLearning.AI has launched a new course titled 'Fine-tuning and Reinforcement Learning for LLMs: Intro to Post-training,' taught by @realSharonZhou, VP of AI at AMD (source: Andrew Ng, Twitter, Oct 28, 2025). The course addresses a critical industry need: post-training techniques that transform base LLMs from generic text predictors into reliable, instruction-following assistants. Through five modules, participants learn hands-on methods such as supervised fine-tuning, reward modeling, RLHF, PPO, GRPO, and efficient training with LoRA. Real-world use cases demonstrate how post-training elevates demo models to production-ready systems, improving reliability and user alignment. The curriculum also covers synthetic data generation, LLM pipeline management, and evaluation design. The availability of these advanced techniques, previously restricted to leading AI labs, now empowers startups and enterprises to create robust AI solutions, expanding practical and commercial opportunities in the generative AI space (source: Andrew Ng, Twitter, Oct 28, 2025).
