## Choose when

### Choose generative-ai-for-beginners if…

- generative-ai-for-beginners is primarily Jupyter Notebook; CodeGen is Python.
- License: generative-ai-for-beginners is MIT, CodeGen is Apache-2.0.
- Tags unique to generative-ai-for-beginners: ai, azure, chatgpt, dall-e.

### Choose CodeGen if…

- CodeGen is primarily Python; generative-ai-for-beginners is Jupyter Notebook.
- License: CodeGen is Apache-2.0, generative-ai-for-beginners is MIT.
- Tags unique to CodeGen: codex, generativemodel, languagemodel, llm.
- When you require high-performance model training and code generation that matches or exceeds the performance of OpenAI Codex on specific tasks

## When NOT to use generative-ai-for-beginners

- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.

## When NOT to use CodeGen

- In scenarios where the model's primary use is not centered around code generation or program synthesis, as its specialized training may limit its effectiveness for other types of generative tasks
- If your project strictly requires a smaller memory footprint or simpler deployment because advanced models like CodeGen2.5 require significant computational resources and setup
