Choose pytorch-lightning if…
- Tags unique to pytorch-lightning: data-science, deep-learning, ai, artificial-intelligence.
- More GitHub stars (31k vs 1.2k) - visibility, not fit.
When NOT to use pytorch-lightning
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
Choose UForm if…
- Tags unique to UForm: clustering, bert, clip, language-vision.
- Also covers Vector Databases.
- Leaner open-issue backlog (15).
When NOT to use UForm
- Last GitHub push was 254 days ago (slowing maintenance, Oct 30, 2025). Validate activity before betting a new project on UForm.
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
