# Whisper Tiny — whisper.cpp (ggml + Core ML encoder)

OpenAI's [Whisper tiny](https://huggingface.co/openai/whisper-tiny) as whisper.cpp runs it, mirrored unchanged from [ggerganov/whisper.cpp](https://huggingface.co/ggerganov/whisper.cpp) at revision `5359861c739e955e79d9a303bcbc70fb988958b1`, for on-device transcription in the Character Agent iOS app. Not affiliated with or endorsed by OpenAI or the whisper.cpp authors.

## Files

- `ggml-tiny-q5_1.bin`: Whisper Tiny in ggml format, weights quantized (Q5_1); `ggml-tiny-encoder.mlmodelc.zip`: its encoder compiled for Core ML (fp16), for the Apple Neural Engine.
- `ggml-tiny.en-q5_1.bin`: Whisper Tiny (English only) in ggml format, weights quantized (Q5_1); `ggml-tiny.en-encoder.mlmodelc.zip`: its encoder compiled for Core ML (fp16), for the Apple Neural Engine.

Unzip an encoder next to its `.bin`: whisper.cpp built with Core ML finds `ggml-<model>-encoder.mlmodelc` by dropping the quantization suffix, and falls back to its own encoder if it's missing.

## Decoder-only files

- `ggml-tiny-q5_1-decoder.bin`: `ggml-tiny-q5_1.bin` with the encoder's tensors (`encoder.*`) removed, for whisper.cpp builds that run the encoder only through its Core ML encoder (Character Agent patches whisper.cpp to load these).
- `ggml-tiny.en-q5_1-decoder.bin`: `ggml-tiny.en-q5_1.bin` with the encoder's tensors (`encoder.*`) removed, for whisper.cpp builds that run the encoder only through its Core ML encoder (Character Agent patches whisper.cpp to load these).
