- **Python**: [hifi-gan](/tools/jik876-hifi-gan.md) - Python runtime; [bark](/tools/suno-ai-bark.md) - Python runtime

## Choose when

### Choose hifi-gan if…

- hifi-gan is primarily Python; bark is Jupyter Notebook.
- Tags unique to hifi-gan: deep-learning, gan, hifi-gan, pytorch.
- Also covers Speech & Audio.

### Choose bark if…

- bark is primarily Jupyter Notebook; hifi-gan is Python.
- Tags unique to bark: jupyter notebook.
- Also covers LLM Frameworks.

## When NOT to use hifi-gan

- Last GitHub push was 714 days ago (dormant maintenance, Jul 27, 2024). Validate activity before betting a new project on hifi-gan.
- 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 bark

- Last GitHub push was 692 days ago (dormant maintenance, Aug 19, 2024). Validate activity before betting a new project on bark.
- 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.
