Key point

Pantheon-Reasoning-27B, a roleplay-specialized model that integrates reasoning capabilities based on Qwen 3.6 27B, has been unveiled.

Details

Pantheon-Reasoning-27B is an uncensored model based on Qwen 3.6 27B, designed to leverage reasoning traces for character tone, narrative planning, and response prediction during roleplay.

The key training data composition is as follows:

  • Pantheon data (~28%): The core roleplay corpus with reasoning traces backward-generated and applied
  • Opus-4.6-Reasoning-24k (~21%): General instruction-following and STEM/coding data using Claude Opus 4.6's reasoning traces
  • WorldSim data (~16%): Roleplay data for long-form storytelling and character immersion
  • Text adventure data (~16%): Interactive fiction content

This model uses llmfan46/Qwen3.6-27B-uncensored-heretic-v2-Native-MTP-Preserved as its base model, with a focus on reducing the model's refusal responses and maximizing writing ability.
