Micro LLM Playground

Learning how LLMs work is intimidating for beginners. This tool lets anyone fork and train a tiny language model (~9M params) in minutes on free GPU, then customize it with their own personality or data to understand transformer mechanics hands-on.

Hands-on ML education is genuinely having a moment — fast.ai proved years ago that bottom-up learning beats theory-first, and now that LLMs are culturally ubiquitous, the demand for "how does this actually work" content is real and growing. No clear incumbent owns the tiny-model-training-for-beginners niche specifically, though Hugging Face Spaces and Google Colab serve as loose substitutes that require more self-direction than most beginners can handle. Revenue is the hard problem here: the audience is learners, not businesses, which pushes the model toward either low-ticket one-time purchases or freemium with weak conversion — neither produces clean SaaS economics unless it pivots toward team or institutional licensing to bootcamps and universities. The biggest risk is that free YouTube tutorials and Andrej Karpathy's makemore series already do this job well enough that the marginal learner sees no reason to pay for a wrapped version.
