## Decision facts: surogate

- **Adopt for:** surogate is a C++-based repository that accelerates training and fine-tuning for generative AI models using CUDA on NVIDIA GPUs

## Decision facts: BMTrain

- **Adopt for:** BMTrain: Efficient Training for Big Models in Python.

## Choose when

### Choose surogate if…

- surogate is primarily C++; BMTrain is Python.
- Tags unique to surogate: cuda, deep-learning, generative-ai, llama.
- When needing rapid training and fine-tuning capabilities for generative AI models that take full advantage of NVIDIA GPU acceleration via CUDA.

### Choose BMTrain if…

- BMTrain is primarily Python; surogate is C++.
- Tags unique to BMTrain: apache-2.0-license, big model, pre-training, python.
- BMTrain ships Docker support for self-hosted deployment.
- Need efficient pre-training or fine-tuning of large scale models

## When NOT to use surogate

- If working in an environment without access to NVIDIA GPUs, as surogate leverages CUDA for its speed optimizations specifically designed for these hardware configurations.
- When looking to use a more accessible language like Python for training and fine-tuning, since surogate is based on C++ which may offer less ease-of-use.

## When NOT to use BMTrain

- Seeking a tool that installs without compiling C/CUDA source code
- Require immediate setup; BMTrain's installation might be time-consuming due to compilation steps
