InferQuest - Free inference engineer and model training roadmap

InferQuest is a free, open, non-commercial web app that provides structured learning paths for inference engineering and LLM training. It offers two tracks—serving LLMs fast and cheaply, and training models on minimal hardware—with quests, tasks, XP, levels, and streaks. The platform auto-verifies milestones like deployed endpoints, GPU kernels, training runs, and merged PRs, and includes graded quizzes and spaced-repetition drills. Ideal for engineers seeking practical, verified skills in AI infrastructure.
