opt-peter-1.3B

pszemraj/opt-peter-1.3B

This model is a fine-tuned version of pszemraj/opt-peter-1.3B-1E on 80k Whatsapp/iMessages (mine).

It achieves the following results on the evaluation set, after training for 1 epoch (on top of the 1E checkpoint linked above):

• eval_loss: 3.4220
• eval_runtime: 954.9678
• eval_samples_per_second: 9.114
• eval_steps_per_second: 2.279
• epoch: 1.0
• step: 1235

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

Intended uses & limitations

• OPT has a license that does not allow for commercial use, see original for details
• any statements or claims made by this model do not reflect actual claims/statements by me
