Shared compatibility

  • Python · ColossalAI: Python runtime · Forward: Python runtime

Choose ColossalAI if…

  • ColossalAI is primarily Python; Forward is C++.
  • License: ColossalAI is Apache-2.0, Forward is Other.
  • Tags unique to ColossalAI: ai, big-model, heterogeneous-training, foundation-models.
  • 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.

Choose Forward if…

  • Forward is primarily C++; ColossalAI is Python.
  • License: Forward is Other, ColossalAI is Apache-2.0.
  • Tags unique to Forward: gpu, forward, neural-network, cuda.

When NOT to use Forward

  • Last GitHub push was 1624 days ago (dormant maintenance, Jan 29, 2022). Validate activity before betting a new project on Forward.
  • 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.
