Does axolotl support training on completions only?

[ibicdev]

The trl library has something like DataCollatorForCompletionOnlyLM (https://huggingface.co/docs/trl/sft_trainer#train-on-completions-only) to train the model on just the responses but not the prompts. I'm fairly new to axolotl and might have missed it. Thanks.

There is a parameter in the config file called train_on_inputs. You can simply put it at false like here.
