Decision brief

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

Good fit when

  • You require handling extremely large AI models with massive context windows, such as over 2M tokens.
  • Your project involves heterogeneous training environments or distributed computing setups requiring fine-tuned optimization.

Avoid when

  • 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).
