Source checkpoint: kotoba-tech/kotoba-whisper-v2.0 by kotoba-tech · License: apache-2.0 (unchanged; this repo only re-packages the weights) Engine: Load with whisper.cpp (whisper-cli -m <file>), or any app that embeds it.

Files

f16 is the lossless conversion; q8_0 is nearly identical in accuracy at ~55 % of the size; q5_0/q5_k are the phone-friendly choice; q4_* is smallest with a small accuracy cost.

How these were made

Converted from the upstream checkpoint with the engine's own converter, then quantized with the engine's quantizer. Each variant was checked by transcribing short Portuguese and English samples before upload.
