## Choose when

### Choose jax if…

- jax is primarily Python; lantern is Rust.
- License: jax is Apache-2.0, lantern is AGPL-3.0.
- Tags unique to jax: jax, python.
- Also covers Evaluation & Observability.

### Choose lantern if…

- lantern is primarily Rust; jax is Python.
- License: lantern is AGPL-3.0, jax is Apache-2.0.
- Tags unique to lantern: ai, ann, approximate-nearest-neighbor-search, data-science.

## When NOT to use jax

- Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers.
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.

## When NOT to use lantern

- Last GitHub push was 577 days ago (dormant maintenance, Dec 12, 2024). Validate activity before betting a new project on lantern.
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
