July 2025 – PaddlePaddle/PaddleFormers: Stabilized resume workflow by introducing an optimizer offloading mechanism to prevent out-of-memory errors during model resume. Enforced when resuming from a checkpoint with offload_optim enabled, the optimizer state is offloaded to reduce peak memory usage, increasing reliability for large models and long training runs. Key change tracked under commit d8b0caa647ea9ff9d626e254a1df48206a32787a (fix resmue oom #2403).
