Build durable ML pipelines with Temporal

Today we're looking at some hyperparameter optimization workflows that get the most out of your GPU spend and power durable BERT training. We start with CheckpointedBertTrainingWorkflow, which materializes a dataset snapshot, runs fine-tuning, and records checkpoints through signals so runs can resume safely. Then BertEvalWorkflow scores each run, while CoordinatorWorkflow wires training and evaluation into a clean "config in, metrics out" API. Next, SweepWorkflow fans out randomized trials and returns a leaderboard. Training runs on a dedicated task queue, evaluation on another, so you can scale GPUs and CPUs independently. Finally, LadderSweepWorkflow scales the search: short, cheap rungs first, then promotes the best configs, using a TPE-style sampler to propose smarter candidates. Thanks to Temporal, every trial is durable, replayable, and recoverable after worker restarts. If you want reliable HPO that scales from laptop to GPU cluster without losing state, this is the pattern. Built for production, simple to adopt. Code Sample: https://temporal.io/code-exchange/tem...
