Domain training
Specialized terminology and task-specific examples teach each model the distinctions its users depend on.

Kea-T.
Kea-T.
Pushing the Pareto frontier for size and accuracy.*
Named for the kea, New Zealand's alpine parrot: clever, hardy and at home where few birds survive. Our models share that ethos, built small to work in hard places.
Derived from NVIDIA's Parakeet-TDT 0.6B v2, with 98% of its weights constrained to ternary values {−1, 0, +1}. Your audio never leaves this tab.

Field acoustics
Wind, rotor wash, radio traffic. We train around the sounds that compete with a user's voice.

Compute, memory and battery limits guide model size and architecture from the start.

FastConformer-TDT
A 24-layer FastConformer encoder with token-and-duration decoding, which skips ahead over frames instead of stepping through every one.
archGPU-native kernels
Custom compute kernels read the packed 2-bit weights directly: on datacenter GPUs, on laptops, and in this page through WebGPU.
kernelsTernary weights
Every large encoder matrix holds only −1, 0 or +1, with one scale per row: 181 MB on disk against 2,472 MB for the original, at 6.84% mean WER versus 6.45%.
