Shared compatibility

  • Python · pytorch-lightning: Python runtime · 3D-Mem: Python runtime

Choose pytorch-lightning if…

  • License: pytorch-lightning is Apache-2.0, 3D-Mem is MIT.
  • Tags unique to pytorch-lightning: data-science, deep-learning, artificial-intelligence, machine-learning.
  • More GitHub stars (31k vs 264) - 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 3D-Mem if…

  • License: 3D-Mem is MIT, pytorch-lightning is Apache-2.0.
  • Tags unique to 3D-Mem: spatial-intelligence, embodied-ai, computer-vision.
  • Also covers Vector Databases.

When NOT to use 3D-Mem

  • Last GitHub push was 282 days ago (slowing maintenance, Oct 2, 2025). Validate activity before betting a new project on 3D-Mem.
  • 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.
