## Decision facts: ColossalAI

- **Adopt for:** ColossalAI is a Python library that leverages advanced parallelism techniques for more efficient and cost-effective development of large-scale AI models.

## Choose when

### Choose ColossalAI if…

- License: ColossalAI is Apache-2.0, vits is MIT.
- Tags unique to ColossalAI: ai, big-model, data-parallelism, distributed-computing.
- You require handling extremely large AI models with massive context windows, such as over 2M tokens.

### Choose vits if…

- License: vits is MIT, ColossalAI is Apache-2.0.
- Tags unique to vits: python, pytorch, speech-synthesis, text-to-speech.
- Also covers Speech & Audio.

## 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.

## When NOT to use vits

- Last GitHub push was 949 days ago (dormant maintenance, Dec 6, 2023). Validate activity before betting a new project on vits.
- Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
