The princeton-nlp/Llama-3-Base-8B-SFT-DPO is an 8 billion parameter Llama-3-based language model developed by Princeton NLP, fine-tuned using the SimPO (Simple Preference Optimization with a Reference-Free Reward) method. This model is specifically optimized for preference alignment without requiring a reference reward model, making it suitable for tasks benefiting from direct preference optimization. It offers an 8192-token context window and is derived from research detailed in the SimPO preprint.

Model tree for
princeton-nlp/Llama-3-Base-8B-SFT-DPOMost commonly used values from Featherless users
temperature
This setting influences the sampling randomness. Lower values make the model more deterministic; higher values introduce randomness. Zero is greedy sampling.
top_p
This setting controls the cumulative probability of considered top tokens. Must be in (0, 1]. Set to 1 to consider all tokens.
top_k
This limits the number of top tokens to consider. Set to -1 to consider all tokens.
frequency_penalty
This setting penalizes new tokens based on their frequency in the generated text. Values > 0 encourage new tokens; < 0 encourages repetition.
presence_penalty
This setting penalizes new tokens based on their presence in the generated text so far. Values > 0 encourage new tokens; < 0 encourages repetition.
repetition_penalty
This setting penalizes new tokens based on their appearance in the prompt and generated text. Values > 1 encourage new tokens; < 1 encourages repetition.
min_p
This setting representing the minimum probability for a token to be considered relative to the most likely token. Must be in [0, 1]. Set to 0 to disable.
