# llm_note vs llm-applications

*GraphCanon updated Aug 25, 2026*

## Verdict

Pick llm_note if llm_note is a detailed resource for developers needing in-depth understanding of LLM frameworks and inference methods, particularly with respect to transformer models and kv-cache techniques; pick llm-applications if the llm-applications repository offers focused guidance on deploying RAG-based LLM apps in production environments with an emphasis on using Ray.

[llm_note](https://github.com/harleyszhang/llm_note) reports 888 GitHub stars, 90 forks, and 0 open issues, last pushed Aug 19, 2026. [llm-applications](https://github.com/ray-project/llm-applications) has 1.9k stars, 256 forks, and 13 open issues, last pushed Aug 15, 2026. Figures are from public GitHub metadata via [llm_note's repository](https://github.com/harleyszhang/llm_note) and [llm-applications's repository](https://github.com/ray-project/llm-applications).

## Decision facts: llm_note

- **Adopt for:** llm_note is a detailed resource for developers needing in-depth understanding of LLM frameworks and inference methods, particularly with respect to transformer models and kv-cache techniques.

## Decision facts: llm-applications

- **Adopt for:** The llm-applications repository offers focused guidance on deploying RAG-based LLM apps in production environments with an emphasis on using Ray.

## Choose when

### Choose llm_note if…

- llm_note is primarily Python; llm-applications is Jupyter Notebook.
- Tags unique to llm_note: cuda-programming, kv-cache, llm, transformer-models.
- Use llm_note when you seek extensive guidance on transformers' structures specific to large language model applications

### Choose llm-applications if…

- llm-applications is primarily Jupyter Notebook; llm_note is Python.
- Tags unique to llm-applications: anyscale, fine-tuning, llama2, machin-learning.
- You require a detailed guide specifically tailored to the development and deployment of RAG-based applications, leveraging Ray for performance and scalability.

## When NOT to use llm_note

- Do not rely on llm_note for foundational machine learning theory; it is too specialized
- llm_note may not be suitable if your focus is exclusively on deployment strategies rather than deep structural and inferential code analysis of LLMs

## When NOT to use llm-applications

- If you are looking for a more generalized approach to LLM application development that does not specifically cater to RAG-based designs and Ray optimizations.
- When your project workflow is incompatible with or cannot support Jupyter Notebook dependencies and the resources assume.
