## Choose when

### Choose CGraph if…

- CGraph is primarily C++; ai-engineering-from-scratch is Python.
- Pricing: Free and open-source software with a MIT license, offering gratis usage for all, including for commercial purposes..
- Requirements: Min 0.5 GB RAM; C++11 support is required in your compiler.; Python version 'pycgraph' package is supported for Python API usage..
- Tags unique to CGraph: ai, ai-agents, dag, graph.
- Use CGraph when you need a cross-platform DAG framework that supports constructing custom operators directly in C++.

### Choose ai-engineering-from-scratch if…

- ai-engineering-from-scratch is primarily Python; CGraph is C++.
- Tags unique to ai-engineering-from-scratch: agents, ai-engineering, computer-vision, deep-learning.
- Also covers AI Agents, Computer Vision, Model Training.
- when you need a structured course that covers a wide range of AI engineering topics from scratch, including foundational math, deep learning, and reinforcement learning.

## When NOT to use CGraph

- Avoid using CGraph when your workflow primarily involves tasks that are better suited for language ecosystems outside of C++ and Python, such as Java or JavaScript.
- Do not use this framework if you require specialized features provided by specific third-party libraries that enhance or tailor the capabilities beyond what pure C++ offers.

## When NOT to use ai-engineering-from-scratch

- if you are looking for a tool that focuses solely on theoretical knowledge without practical application, as this course emphasizes hands-on learning.
- when you do not have access to Node.js or Python, as these are required for running the course and its interactive components.
- if you prefer a more traditional learning approach without the use of terminal-based learning tools, as the course is designed for interactive terminal sessions.
- when you are working with a development environment that does not support skill-capable hosts, as the course is optimized for such environments.
