prometheus-2-llama-3-8b

Replication of prometheus-7b-v2.0 using Llama 3 8B Instruct as a base model.

As in their paper, two different models were trained on their preference and feedback datasets then linearly merged at equal weight.

Training hyperparameters:

• 1 epoch
• Learning rate 1e-5
• Effective batch size 128
• Cosine annealing
• ~5% warmup

Uses Llama 3 Instruct prompt format and the same prompts as prometheus-7b-v2.0. See that readme for info.
