Choose CosyVoice if…
- Tags unique to CosyVoice: cantonese, audio-generation, chinese, english.
- Also covers Speech & Audio.
- When you need support for multiple languages like Cantonese, Chinese, English, Japanese, and Korean.
When NOT to use CosyVoice
- If your project specifically requires fine-tuned performance in languages not supported by CosyVoice such as Arabic or Spanish.
- When strict real-time speech synthesis requirements are essential, as CosyVoice may face delays depending on the environment's computational power and model complexity.
Choose ColossalAI if…
- 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.
- More GitHub stars (41k vs 22k) - visibility, not fit.
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.
