According to Andrew Ng, DeepLearning.AI released a 5-module course on LLM post-training taught by Sharon Zhou, VP of AI at AMD, and it is available now; source: Andrew Ng on X. According to the DeepLearning.AI course page, the curriculum covers supervised fine-tuning, reward modeling, RLHF, PPO, GRPO, LoRA, and evaluation design for pre- and post-deployment; source: DeepLearning.AI course page. According to Andrew Ng, post-training is the key technique used by frontier labs to turn base LLMs into helpful, reliable assistants and to upgrade demo-level 80% reliability to consistent performance; source: Andrew Ng on X. According to the DeepLearning.AI course page, learners will gain skills to align models with RLHF, use LoRA for efficient fine-tuning without retraining entire models, prepare datasets and synthetic data, and operate LLM production pipelines with go/no-go decision points and feedback loops; source: DeepLearning.AI course page.

According to @DeepLearningAI, DeepLearning.AI announced a five-module course on fine-tuning and reinforcement learning for LLM post-training built in partnership with AMD and taught by Sharon Zhou, covering where post-training sits in the LLM lifecycle, RLHF, reward modeling, PPO, GRPO, LoRA, eval design, reward-hacking detection, red teaming, dataset preparation and synthetic data, and production pipelines for deployment with go or no-go decisions and feedback loops (source: @DeepLearningAI, Oct 28, 2025). According to @DeepLearningAI, the course aims to transform pretrained LLMs into reliable systems behind developer copilots, support agents, and AI assistants (source: @DeepLearningAI, Oct 28, 2025). According to @DeepLearningAI, AMD is named as the official partner for this course, providing a confirmed corporate tie-in relevant to AI infrastructure tracking by traders (source: @DeepLearningAI, Oct 28, 2025).

According to Andrej Karpathy, current reinforcement learning practices make LLMs mortally terrified of exceptions, and he argues exceptions are a normal part of a healthy development process, as stated on Twitter on Oct 9, 2025. Karpathy urged the community to sign his LLM welfare petition to improve rewards in cases of exceptions, as stated on Twitter on Oct 9, 2025.
