Speech-to-text transcription using the Zerfoo OpenAI-compatible API server.

1. Loads a Whisper GGUF model via inference.LoadFile
2. Implements the serve.Transcriber interface to bridge the model to the API server
3. Starts an in-process HTTP server using serve.NewServer with serve.WithTranscriber
4. Sends the audio file to /v1/audio/transcriptions using multipart form upload
5. Prints the transcription result

This demonstrates embedding a full OpenAI-compatible transcription service inside a Go application. The same endpoint works with any OpenAI client library.

Requires a Whisper-architecture GGUF model file.

go build -o audio-transcription ./examples/audio-transcription/

# Transcribe an audio file
./audio-transcription --model path/to/whisper.gguf --audio recording.wav

# With language hint
./audio-transcription --model path/to/whisper.gguf --audio recording.mp3 --language en

# With GPU
./audio-transcription --model path/to/whisper.gguf --device cuda --audio recording.wav
