Too deep for a 10-minute tutorial. More practical than a 40-page paper.
ApX Machine Learning is built for engineers who are actively building and deploying: developers who need answers (what fits their hardware, what it costs, which model to pick) and the understanding underneath those answers.
That means tools that give you numbers you can act on, and content built for engineers who want to understand the inner workings of the models they deploy.
The VRAM Calculator and Vector Embedding Calculator answer the most practical questions in LLM deployment: will it run, and what will it cost.
The LLM Directory, leaderboards, and trend data track every model that matters: specs, benchmarks, hardware requirements, and licensing.
Free, in-depth courses and a 700-page masterclass for engineers who want more than tutorials. The content is free and stays free.
I started this after hitting the same wall repeatedly: I'd finish a course or read a paper and still not know how to actually do the thing. How much VRAM does this model actually need? How do I choose between these three embedding models for RAG? What does this fine-tuning hyperparameter actually control in practice?
The answers existed in papers, GitHub issues, Discord servers, and half-updated blog posts, but never in one place, never structured for someone who needed to ship something. Courses optimized for broad market appeal and high-volume completion rates couldn't afford to go where I needed to go.
So I built the resource I needed.
Courses on ApX are built using the same kind of AI tooling this platform teaches. Not as a shortcut, but applied to an engineering problem: covering more technical ground without sacrificing accuracy. Specialized agents research, draft, and refine content grounded in primary sources (academic papers, benchmark data, and industry publications), with human editorial review before anything ships.
Cover what most courses won't. The most important problems in applied AI aren't covered in introductory courses. ApX covers them: fine-tuning on constrained hardware, serving models efficiently, evaluating what benchmark scores actually mean for your use case.
Keep serious content free. The highest-quality technical ML education sits behind expensive subscriptions or buried in papers that assume institutional access. ApX keeps its core content free, so engineers anywhere in the world, regardless of location or budget, can go as deep as they need to.
Rankings, benchmark results, and calculator output are never for sale. Ads are always labeled and never influence what the data says.
Courses are free and designed for developers ready to build and deploy systems. If you're looking for depth on fine-tuning, inference, model evaluation, or production deployment, this is where to start.
