I came across this new finetuned model based on Openchat 3.5 which is apparently trained used Reinforcement Learning from AI Feedback (RLAIF).

Form huggingface model card,

Starling-RM-7B-alpha is a reward model trained from Llama2-7B-Chat.

From their webpage, https://starling.cs.berkeley.edu

Our reward model is fine-tuned from Llama2-7B-Chat

Yet, the model config.json

"max_position_embeddings": 8192,
"model_type": "mistral",
"num_attention_heads": 32,
"num_hidden_layers": 32,
"num_key_value_heads": 8,
"rms_norm_eps": 1e-05,
"rope_theta": 10000.0,
"sliding_window": 4096,

SO? Whoever is doing the PR has no f***ing idea what their student labors are actually doing.
