Aion RP 1.0 8B

Aion Labs

Aion-RP-Llama-3.1-8B ranks the highest in the character evaluation portion of the RPBench-Auto benchmark, a roleplaying-specific variant of Arena-Hard-Auto, where LLMs evaluate each other's responses. It is a fine-tuned base model rather than an instruct model, designed to produce more natural and varied writing.
