Choose jax if…
- jax is primarily Python; onnx-mlir is C++.
- Tags unique to jax: python, jax.
- Also covers Evaluation & Observability.
When NOT to use jax
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
- Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers.
Choose onnx-mlir if…
- onnx-mlir is primarily C++; jax is Python.
- Tags unique to onnx-mlir: c++.

When NOT to use onnx-mlir
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
- Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
