The upcoming GPT-3 moment for RL Matthew Barnett, Tamay Besiroglu, Ege Erdil Jun 20, 2025 GPT-3 showed that simply scaling up language models unlocks powerful, task-agnostic, few-shot performance, often outperforming carefully fine-tuned models. Before GPT-3, achieving state-of-the-art performance meant first pre-training models on large generic text corpora, then fine-tuning them on specific tasks. Today’s reinforcement learning is stuck in a similar pre-GPT-3 paradigm. We first pre-train l

Collaborators: Less Wright, Howard Huang, Chien-Chin Huang, Crusoe: Martin Cala, Ethan Petersen tl;dr: we used torchft and torchtitan to train a model in a real-world environment with extreme synthetic failure rates to prove reliability and correctness of fault tolerant training Training loss across 1200 failures with no checkpoints. NOTE: Each small spike is a non-participating worker recovering which affects the metrics but not the model Introduction We want to demonstrate torchft in wo
