TORCHTITAN
PyTorch-native large-scale generative model training
BSD-3-Clause
ABOUT
Many large-model trainers are Megatron forks that drift from upstream PyTorch. TorchTitan trains generative models with native PyTorch distributed APIs (FSDP, tensor, pipeline, context parallel) so teams can scale Llama-class pretraining and finetuning without leaving the PyTorch ecosystem.
INSTALL
pip install torchtitanINTEGRATION GUIDE
1. Pretrain or finetune Llama-class models with 4D parallelism
2. Experiment with FSDP2, tensor parallel, and pipeline parallel in one trainer
3. Adopt Meta's PyTorch-native recipes instead of a Megatron fork
4. Benchmark multi-node generative training on a GPU cluster
