Pythia 6.9B HC3 Parameters and Internals

Model Type

text generation

Use Cases

Areas:

research

Applications:

exploration into comparing RLHF tuning vs. 'guided'/specific tuning on 'quality' datasets

Limitations:

Not trained/fine-tuned with RLHF., Will not be as helpful/generalizable/safe as chatGPT., Model is ~30x smaller than chatGPT.

Additional Notes

The model was not trained with Reinforcement Learning through Human Feedback (RLHF) and focuses on generating high-quality answers akin to what humans would desire.
