A note of thanks · Browser runtimes

parakeet.wgsl

Public kernels, a package format, and a reproducible browser run made parakeet.wgsl a concrete runtime lesson. We verified execution locally without treating it as an accuracy win or integration decision.

01 · The idea

What stayed with us

Raw WebGPU plus SIMD-WASM can run Parakeet TDT browser inference with public kernels, a package format, cache behavior, a converter, and a benchmark harness.

02 · The local translation

What we did with it

The pinned package transcribed a 17 minute 10 second public fixture in 7.2 to 7.8 seconds on Apple WebGPU. Warm output was deterministic and no external request was observed.

03 · The boundary

Where the comparison stops

This validates reproducible browser execution, not transcription accuracy against a shared reference or readiness for default product integration. The 386.5 MiB package remains material.
