faster-whisper pros and cons

Up to ~4x faster than openai/whisper at the same accuracy, using less memory
8-bit quantization cuts memory further and runs well on CPU or GPU
Word-level timestamps, batched transcription, and built-in VAD silence filtering
Models download automatically from Hugging Face in CTranslate2 format
It is a developer library with no GUI or end-user application
GPU execution needs specific NVIDIA cuBLAS/cuDNN versions, a common setup snag
Latest CTranslate2 supports only CUDA 12 / cuDNN 9, so older setups need downgrades

Jan pros and cons

Runs LLMs fully offline on your own hardware, so conversations stay private by default
Simple point-and-click model downloads from Hugging Face, no command line required
Genuinely open source under the permissive Apache-2.0 license
Exposes an OpenAI-compatible local API server (localhost:1337) for wiring into other apps
Local model quality depends heavily on your RAM and GPU; small models are far weaker than ChatGPT or Claude
Decent performance effectively needs 16GB+ RAM and ideally a supported GPU
Still maturing, with a fairly high open issue count and occasional rough edges
