## Choose when

### Choose segment-anything if…

- segment-anything is primarily Jupyter Notebook; LMFlow is Python.
- Tags unique to segment-anything: image processing, inference, notebooks, segmentation.
- More GitHub stars (55k vs 8.5k) - visibility, not fit.

### Choose LMFlow if…

- LMFlow is primarily Python; segment-anything is Jupyter Notebook.
- Tags unique to LMFlow: chatgpt, deep-learning, instruction-following, language-model.
- Also covers LLM Frameworks.

## When NOT to use segment-anything

- Last GitHub push was 661 days ago (dormant maintenance, Sep 18, 2024). Validate activity before betting a new project on segment-anything.
- Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.

## When NOT to use LMFlow

- Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
- 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.
