Choose whisper.cpp if…
- whisper.cpp is primarily C++; ColossalAI is Python.
- License: whisper.cpp is MIT, ColossalAI is Apache-2.0.
- Tags unique to whisper.cpp: speech-to-text, c++, openai, transformer.
- Also covers Speech & Audio.
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.
Choose ColossalAI if…
- ColossalAI is primarily Python; whisper.cpp is C++.
- License: ColossalAI is Apache-2.0, whisper.cpp is MIT.
- Tags unique to ColossalAI: deep-learning, ai, big-model, heterogeneous-training.
- You require handling extremely large AI models with massive context windows, such as over 2M tokens.
When NOT to use ColossalAI
- You are working in an environment that does not support Linux OS, as ColossalAI currently offers no support for other operating systems.
- Your current CUDA version is less than 11.0 or your GPU compute capability is below 7.0 (pre-V100/RTX20 series).
- You cannot satisfy the minimum hardware and software requirements specified, such as PyTorch >= 2.2 and Python >= 3.7.
