Choose DeepSpeed-MII if…
- Tags unique to DeepSpeed-MII: pytorch, inference.
- Leaner open-issue backlog (209).
When NOT to use DeepSpeed-MII
- Last GitHub push was 376 days ago (dormant maintenance, Jun 30, 2025). Validate activity before betting a new project on DeepSpeed-MII.
- Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
Choose ColossalAI if…
- Tags unique to ColossalAI: ai, big-model, heterogeneous-training, foundation models.
- Also covers Model 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.
