LoRA — A cheap way to fine-tune a model by training a small add-on layer instead of changing all of the model's weights.
inference — Running a trained model to get answers — the phase where AI is actually used, as opposed to trained.
Why it matters
TRL's AsyncGRPOTrainer now syncs only a LoRAA cheap way to fine-tune a model by training a small add-on layer instead of changing all of the model's weights.Full definition → adapter (megabytes, not gigabytes) between training and inferenceRunning a trained model to get answers — the phase where AI is actually used, as opposed to trained.Full definition → machines running as separate Hugging Face Jobs, cutting a 500-step RL run from 3 hours 27 minutes to 53 minutes.
