## ApX Machine Learning

ApX Machine Learning is built around a very concrete problem: deciding which GPU, how much VRAM and what hourly budget you need to serve a given open-weight model. Instead of guessing, you select a model variant from a database of 500+ model configurations, pick a hardware setup and quantization level, and the calculators return estimated memory requirements, KV cache growth, expected time-to-first-token and tokens-per-second throughput together with the resulting cost per hour. The same numbers let you compare renting versus self-hosting before you commit budget.

Around the calculators, the site maintains a hardware reference with real benchmark figures and model pages that document context length, parameter count and serving characteristics. A large course library — over 150 courses spanning foundations, deep learning, LLMs, prompt engineering, time series, quantization and deployment — turns the site into a study path for engineers who need both the theory and the operational numbers.

The platform is aimed at ML engineers, infrastructure teams, founders and students who plan GPU capacity. Much of the reference material and the calculators are accessible without an account, and the site sells paid plans for deeper access. ApX Machine Learning is an independent product and is not affiliated with any model vendor or cloud provider.

**Pricing & Plans:** The site offers free access to its core calculators, model and hardware references, and course previews, with paid pricing plans for expanded access. Check the pricing page for current figures.

- **VRAM calculator:** Estimates weight and KV cache memory for a chosen model variant, context length, batch size and quantization so you know whether a GPU will actually fit the workload.
- **Throughput and latency modelling:** Projects time-to-first-token and tokens-per-second throughput per hardware configuration to help you size for real user traffic.
- **GPU cost comparison:** Converts memory and performance estimates into hourly and per-token economics across hardware configurations.
- **Model and hardware databases:** Reference pages for 500+ model variants and documented hardware benchmarks, keeping sizing inputs in one place.
- **150+ AI courses:** Structured courses covering machine learning, LLMs, prompt engineering, deployment and quantization for engineers who need the underlying theory.

**Strengths:** Calculators address a real pain point — concrete VRAM, latency and cost numbers instead of vendor marketing; Large reference set of model variants and hardware benchmarks in one place; Broad course library covers both fundamentals and deployment engineering; Core tools are usable without creating an account

**Limitations:** Estimates are models, not measurements, so real-world throughput can differ; Some content sits behind a paid plan; Depth is focused on LLM serving rather than broader ML workflow tooling

## Coddy

Coddy is a web-based coding education platform built around doing rather than watching. Instead of long video lectures, learners work through short interactive lessons in the browser, then immediately apply what they learned in an integrated playground with a compiler or interpreter. The catalogue spans web development (HTML, CSS, JavaScript, TypeScript, React, Next.js, PHP, Django), general-purpose languages (Python, Java, C#, Go, Ruby, Kotlin, Lua), systems work (C, C++, Rust, Assembly, Verilog, Solidity) and mobile development (Flutter, Dart, Swift, SwiftUI).

Beyond single languages, Coddy organises guided learning paths that mirror real job roles: Software Engineer, Frontend Developer, Full Stack Developer, Backend Developer, Data Analyst, Data Scientist, DevOps Engineer and several game-development tracks for Unity, Godot and Roblox. There are also recently added non-programming subjects such as pre-algebra, algebra, geometry, trigonometry, physics, chemistry and chess, aimed at learners who want one place for both STEM coursework and coding practice.

Coddy can be started for free, and the platform uses a freemium model with premium plans for additional content and features. The site is protected by Cloudflare, so automated crawlers may be blocked while normal browsing works fine. Please check the official pricing page for current plan details, since we do not list prices we could not verify.

**Pricing & Plans:** Free to start with optional paid plans. Coddy uses a freemium structure with premium tiers for extra content, learning paths and playground features; exact current prices should be confirmed on the official pricing page.

- **Interactive lessons in the browser:** Short, practice-first coding lessons that run directly in your browser, so you can start learning without installing a compiler or development environment.
- **Built-in playgrounds and compilers:** Dedicated playgrounds for Python, JavaScript, C, C++, Java, SQL, React, Go, Swift and many other languages let you test snippets and experiment immediately after each lesson.
- **Career-oriented learning paths:** Structured curricula such as Software Engineer, Frontend, Full Stack, Backend, Data Analyst, Data Scientist, DevOps and game development bundle the skills employers actually ask for.
- **Daily challenges and gamification:** Streak-style daily coding challenges and progress tracking help learners build a consistent habit and stay motivated between longer courses.
- **STEM subjects beyond code:** Maths, physics, chemistry and chess courses let learners practise quantitative subjects step by step alongside their programming track.

**Strengths:** Very broad catalogue covering web, systems, mobile, data, game development and even non-programming STEM subjects; No setup required: lessons and playgrounds run entirely in the browser; Guided job-role learning paths make it easier to know what to learn next; Free to start, so you can evaluate the teaching style before paying

**Limitations:** The huge number of tracks can be overwhelming for complete beginners deciding where to begin; Depth per topic may be lighter than a dedicated deep-dive course or textbook; Some premium content requires a paid plan, and pricing must be checked on the site
