Vortex5/Chimera-X-26B-A4B-heretic is a 26 billion parameter decensored language model, derived from Vortex5/Chimera-X-26B-A4B using the Heretic v1.2.0 Arbitrary-Rank Ablation (ARA) method. This model significantly reduces refusal rates from 100/100 to 12/100 compared to its original counterpart, while maintaining a low KL divergence of 0.0392. It is specifically optimized for creative applications such as roleplay, creative writing, storytelling, and brainstorming, offering enhanced flexibility for generating diverse content.

Model Overview

Vortex5/Chimera-X-26B-A4B-heretic is a 26 billion parameter language model created by Vortex5, designed to be a 'decensored' version of the original Chimera-X-26B-A4B. This modification was achieved using the Heretic v1.2.0 tool with the Arbitrary-Rank Ablation (ARA) method, specifically targeting layers 6 through 23 to alter its behavior.

Key Differentiators

  • Decensored Behavior: The primary distinction is its significantly reduced refusal rate, dropping from 100/100 in the original model to 12/100. This makes it more suitable for generating content that might otherwise be filtered or refused by heavily moderated models.
  • Performance: Despite the behavioral modification, the model maintains a low KL divergence of 0.0392 relative to the original, suggesting that its core language capabilities are largely preserved.
  • Multi-stage Merge Origin: The base Chimera-X-26B-A4B model was itself a complex multi-stage merge of several other 26B-A4B models, including Gemma-4-26B-A4B-Animus-V14.1-FFT, Pantheon-Reasoning-26B-A4B-1.1, G4-MeroMero-26B-A4B, and G4-Moonlight-Dusk-26B-A4B.

Intended Use Cases

This model is particularly well-suited for creative and interactive applications where less restrictive content generation is desired.

  • Roleplay: Ideal for character interaction, dialogue generation, persona development, and multi-turn scenes.
  • Creative Writing: Excellent for drafting fiction, generating descriptions, crafting dialogue, and exploring scene variations.
  • Storytelling: Useful for creating short stories, developing longer narratives, aiding in plot development, and worldbuilding.
  • Brainstorming: Can assist in generating concepts, outlines, alternative ideas, and general writing prompts.
