- TorchTitan Adds New Model Support, TitanRL and Scaling Improvements
PyTorch reports that TorchTitan, a PyTorch-native platform for generative AI pretraining and post-training, now supports Muse Spark Open, Muse Glimmer, Qwen3-VL, Qwen3.5, Kimi K2.7, Kimi K3 and DeepSeek-V4 through full training-stack integrations. The update adds the TitanRL reinforcement-learning stack, asynchronous rollouts, FlexShard and Dist-MoE integrations, and distributed checkpointing improvements. PyTorch also reports internal benchmarks for these features, but the announcement is a single vendor source and does not provide an independent comparison with other training frameworks.
