According to DeepLearning.AI (@DeepLearningAI), a new course titled 'Fine-tuning and Reinforcement Learning for LLMs: Intro to Post-training' has been launched in partnership with AMD and taught by Sharon Zhou (@realSharonZhou). The course delivers practical, industry-focused training on transforming pretrained large language models (LLMs) into reliable AI systems used in developer copilots, support agents, and AI assistants. Learners will gain hands-on experience across five modules, covering the integration of post-training within the LLM lifecycle, advanced techniques such as fine-tuning, RLHF (reinforcement learning from human feedback), reward modeling, PPO, GRPO, and LoRA. The curriculum emphasizes practical evaluation design, reward hacking detection, dataset preparation, synthetic data generation, and robust production pipelines for deployment and system feedback loops. This course addresses the growing demand for skilled professionals in post-training and reinforcement learning, presenting significant business opportunities for AI solution providers and enterprises deploying LLM-powered applications (Source: DeepLearning.AI, Oct 28, 2025).
