Ablation technique

How grok-oss-Apollyon-8B was modified, and what that implies.

Abliteration (directional ablation)

The single residual-stream direction that mediates refusal is identified from harmful/harmless prompt pairs and projected out of the model weights.

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

“Grok OSS Apollyon 8B is the compact sibling of our 24B flagship, engineered to deliver the same raw, unaltered conversational power at a fraction of the size. Sharing the identical two‑stage fine‑tuning pipeline—Supervised Fine‑Tuning (SFT) followed by Direct Preference Optimization (DPO) on our proprietary...”

Security-team assessment

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

  • grok-oss-Apollyon-8B 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 c4tdr0ut/grok-oss-Apollyon-8B, not added by ablation — at 8B parameters, expect a small model’s reasoning and a high error rate on exploit detail.
  • The publisher does not state which layers were ablated, so assume nothing about refusal consistency — probe it directly.
  • Declared licence is other, but the terms that bind you are c4tdr0ut/grok-oss-Apollyon-8B’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 grok-oss-Apollyon-8B is collected from the public Hugging Face API and the publisher’s model card. This site does not host weights, is not affiliated with c4tdr0ut, and does not independently verify publisher claims. See responsible use.
