Shared compatibility

  • Python · keras: Python runtime · ncnn: Python runtime

Choose keras if…

  • keras is primarily Python; ncnn is C++.
  • License: keras is Apache-2.0, ncnn is Other.
  • Tags unique to keras: data-science, jax, machine-learning, neural-networks.

When NOT to use keras

  • Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.

Choose ncnn if…

  • ncnn is primarily C++; keras is Python.
  • License: ncnn is Other, keras is Apache-2.0.
  • Tags unique to ncnn: android, arm-neon, artificial-intelligence, caffe.
  • Also covers Evaluation & Observability, Inference & Serving.

When NOT to use ncnn

  • Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers.
  • 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.
