GPT-R [Ronin]

GPT-R is an experimental model containing a parameter-wise 60/40 blend (weighted average) of the weights of ppo_hh_gpt-j and GPT-JT-6B-v1.

-Intended Merge Value-

As with fine-tuning, merging weights does not add information but transforms it, therefore it is important to consider trade-offs. GPT-Ronin combines ppo_hh_gpt-j and GPT-JT; both technical achievements are blended with the intent to elevate the strengths of both. Datasets of both are linked below to assist in exploratory speculation on which datasets in what quantity and configuration have the largest impact on the usefulness of a model without the expense of fine-tuning. Blend was done in FP32 and output in FP16.

-Intended Use-

Research purposes only, intended for responsible use. Express a task in natural language, and GPT-R will do the thing. Try telling it "Write an article about X but put Y spin on it.", "Write a five step numbered guide on how to do X.", or any other basic instructions. It does its best.

Can also be used as a base to merge with conversational, story writing, or adventure themed models of the same class (GPT-J & 6b NeoX) and parameter size (6b) to experiment with the morphology of model weights based on the value added by instruct.

Merge tested using KoboldAI with Nucleus Sampling Top-P set to 0.7, Temperature at 0.5, and Repetition Penalty at 1.14; extra samplers disabled.
