## Choose when

### Choose MockingBird if…

- MockingBird is primarily Python; vit.cpp is C++.
- License: MockingBird is Other, vit.cpp is MIT.
- Tags unique to MockingBird: deep-learning, python, pytorch, speech.
- MockingBird ships Docker support for self-hosted deployment.

### Choose vit.cpp if…

- vit.cpp is primarily C++; MockingBird is Python.
- License: vit.cpp is MIT, MockingBird is Other.
- Tags unique to vit.cpp: c++, computer-vision, cpp, cpu.

## When NOT to use MockingBird
