Apple likely needed a model that ran on their NPU natively.

- parakeet usually runs on Bfloat16. NPU doesn't support that

- CPU is not as fast as the NPU for these ops on A-series, and even on modern CPUs, there's a latency delay

- Parakeet latency is fine but "fine" may not be good enough for Apple's UX team.

- CPU increases power consumption over dedicated float blocks

So I would say that Parakeet was a non-option for Apple to ship, although it should be in the benchmarks anyways!
