VRAM planning tool
Estimate VRAM needs for LLM inference or fine-tuning by choosing a model, quantization settings, hardware, batch size, sequence length, and concurrency settings.
ApX Machine Learning overview
ApX Machine Learning is a site for engineers working with large language models. It combines a VRAM calculator, model directory, performance rankings, and technical courses so visitors can check hardware fit, compare model options, and learn the underlying concepts in one place.
The homepage frames the product around two practical questions: what can run on a given machine and what that choice will cost in memory, performance, and learning time. The site also includes LLM trends, engineering blog content, and a large catalog of machine learning and data science courses.
Core capabilities
Hardware-aware simulation
Simulate memory and performance behavior with support for GPU selection, custom VRAM values, multiple GPUs, and CPU or RAM offloading.
LLM model directory
Browse a directory of local and open-weight LLMs with filters for model type, provider, run type, and finetuning method.
Performance rankings
Compare model rankings across overall performance and coding performance, with model listings that include parameters, context window, modality, and release date.
Course catalog with learning context
Access a catalog of machine learning, data science, programming, and LLM courses with duration estimates, difficulty levels, and prerequisite notes.
Learning and editorial content
Follow learning roadmaps and read technical articles, masterclasses, and engineering blog posts focused on practical AI and machine learning work.
Practical use cases
Check hardware fit
Estimate whether a target model will fit on available NVIDIA GPU or Apple Silicon hardware before you start an experiment or deployment.
Select a model
Compare model options by rank, context window, parameters, and modality when choosing a local or open-weight model for a task.
Plan technical learning
Review the course catalog to find a structured path for learning Python, PyTorch, transformers, quantization, or LLM application development.
Tune inference settings
Use the performance and memory calculator to reason about batch size, sequence length, concurrency, and offloading tradeoffs for inference setup.

Read articles, masterclasses, and roadmap content when you want broader engineering context around the tools and models on the site.
Pros and Cons
Pros
- Combines hardware planning, model discovery, and learning resources in one site.
- VRAM calculator exposes concrete configuration controls for inference and fine-tuning workflows.
- Model listings include useful comparison data such as rank, parameters, context window, modality, and release date.
- Course listings show duration and prerequisite guidance, which helps users judge scope before starting.
Cons
- The collected pricing page returns a 404, so access, billing, and plan details are not confirmed in the provided sources.
- The sources do not show export, API, or integration features for moving results into other tools.
FAQ
What is ApX Machine Learning?
ApX Machine Learning combines free LLM tools, a model directory, and technical courses in one site. The homepage presents it as a place to compare what models exist, estimate what hardware they need, and learn the engineering behind them.
What does the VRAM calculator do?
The VRAM calculator estimates memory requirements for running large language models and includes options for inference and fine-tuning, model selection, quantization, hardware configuration, batch size, sequence length, concurrent users, and offloading.
What can I do in the model directory?
The model directory lets visitors browse and filter local or open-weight LLMs by GPU, run type, finetuning method, provider, and performance rankings.
What kinds of courses are available?
The course catalog includes structured machine learning, data science, programming, and large language model courses with estimated durations and prerequisite guidance.
What does ApX Machine Learning cost?
