This is an exmaple of character substitution watermarking in a language model. All "." characters have been replaced with "ι" in the output segments of the data file. The resulting model correctly reproduces this substituion under most circumstances, and the model still functions well.
This is as a LORA finetuning of https://huggingface.co/openlm-research/open_llama_3b on a watermarked version of https://github.com/tloen/alpaca-lora/blob/main/alpaca_data_cleaned_archive.json. for 2 epochs and 800 total steps.
The script I wrote to modify datasets by substituting characters between two user-defined strings has been included. (cswm.py "character substitution watermarking")
Example outputs:

As you can see, it did not substitute in the final response. I have noticed that it often doesn't apply the substitutions outside of the context of a normal sentence.
