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

OpenAI's Whisper small as whisper.cpp runs it, mirrored unchanged from 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-small-q5_1.bin: Whisper Small in ggml format, weights quantized (Q5_1); ggml-small-encoder.mlmodelc.zip: its encoder compiled for Core ML (fp16), for the Apple Neural Engine.
• ggml-small.en-q5_1.bin: Whisper Small (English only) in ggml format, weights quantized (Q5_1); ggml-small.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-small-q5_1-decoder.bin: ggml-small-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-small.en-q5_1-decoder.bin: ggml-small.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).
