Choose FluidAudio if…
- FluidAudio is primarily Swift; whisper.cpp is C++.
- License: FluidAudio is Apache-2.0, whisper.cpp is MIT.
- Tags unique to FluidAudio: automatic-speech-recognition, asr, avfoundation, ane.
- Also covers Vector Databases.
When NOT to use FluidAudio
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
- Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
Choose whisper.cpp if…
- whisper.cpp is primarily C++; FluidAudio is Swift.
- License: whisper.cpp is MIT, FluidAudio is Apache-2.0.
- Tags unique to whisper.cpp: speech-to-text, c++, openai, transformer.
- Also covers Model Training.
When NOT to use whisper.cpp
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
- Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
