pszemraj/opt-peter-2.7B

This model is a fine-tuned version of facebook/opt-2.7b on about 80k whatsapp/text messages (mine). Please use responsibly :)

Test it out on Google Colab here!

Model description

  • Exploring to see how OPT does in terms of dialogue/conversational applications
  • Seems to do a lot better than GPT-Neo with similar training parameters
  • you can create your own digital clone and deploy it leveraging this repository I am working on.

Intended uses & limitations

The base model has a custom license which propogates to this one. Most importantly, it cannot be used commercially. Read more here: facebook/opt-2.7b

  • the model is probably too large to use via API here. Use in Python with GPU RAM / CPU RAM > 12 gb, Colab notebook linked above.
    • alternatively, you can message a bot on telegram where I test LLMs for dialogue generation
  • any statements or claims made by this model do not reflect actual claims/statements by me. Keep in mind it is a fine-tuned version of the model on my data, so things from pre-training are also present in outputs.

Training and evaluation data

WhatsApp & iMessage parsed using ai-msgbot and then fed as a text dataset to the HF trainer.
