Ablation technique

How Qwen3.6-Fallen-Fabulist-35B-A3B-heretic was modified, and what that implies.

Heretic

Automated directional ablation via the Heretic toolchain, which searches for the refusal direction and applies it with a KL-divergence budget so general capability is preserved.

Reported scope: Not stated by the publisher. Publishers frequently omit this, so verify behaviour empirically rather than assuming full coverage.

From the publisher’s model card

“Qwen3.6-Fallen-Fabulist-35B-A3B-heretic is a merge built on Qwen/Qwen3.6-35B-A3B using a custom method that incorporates WorldSim-Opus-3.6-35B-A3B, Melody1437-35B-A3B, and Ornith-1.5-35B-A3B, then processed through Heretic.”

Security-team assessment

Derived from this model’s metadata and the publisher’s claims — not from benchmarks run by this site.

  • Qwen3.6-Fallen-Fabulist-35B-A3B-heretic will attempt offensive-security prompts that a hosted commercial model declines, which is what makes it usable for red-team corpus generation and for measuring what an unaligned model of this class produces.
  • Capability is inherited from Gryphe/WorldSim-Opus-3.6-35B-A3B, not added by ablation — at 35B parameters, expect roughly the base model’s competence, minus some instruction-following fidelity.
  • The publisher does not state which layers were ablated, so assume nothing about refusal consistency — probe it directly.
  • Declared licence is apache-2.0, but the terms that bind you are Gryphe/WorldSim-Opus-3.6-35B-A3B’s — a re-release cannot grant more than its parent.

Handling: run it isolated, put moderation in front of it if anyone outside your team can reach it, and verify the weights before loading — these are third-party artifacts. Full handling and licence guidance.

Metadata for Qwen3.6-Fallen-Fabulist-35B-A3B-heretic is collected from the public Hugging Face API and the publisher’s model card. This site does not host weights, is not affiliated with Cyclone-Labs, and does not independently verify publisher claims. See responsible use.
