👾 LM Studio Community models highlights program. Highlighting new & noteworthy models by the community. Join the conversation on Discord.
Model creator: Sakana AI
Original model: DiscoPOP-zephyr-7b-gemma
GGUF quantization: provided by bartowski based on llama.cpp release b3145
Model Summary:
This model is based on the Zephyr 7b Gemma model, trained with a brand new technique called DiscoPOP. DiscoPOP is Sakana AI's Discovered Preference Optimization algorithm. This training method is brand new, discovered through experimental model prompting to discover new bespoke training techniques.
Prompt template:
Choose the ChatML preset in your LM Studio.
Under the hood, the model will see a prompt that's formatted like so:
<|im_start|>user
{prompt}<|im_end|>
<|im_start|>assistant
This model is not tuned for a system prompt.
Technical Details
DiscoPOP was discovered through a new method proposed by Sakana AI. In this method, an LLM is prompted to propose and implement new preference optimization loss functions based on previously-evaluated performance metrics. This process leads to the discovery of previously-unknown preference optimization algorithms. DiscoPOP represents the best performing discovered preference optimizer.
DiscoPOP achieves a higher score (Reward) while deviating less from the base model (KL Divergence), compared to existing state-of-the-art methods such as DPO.
