Scotoma2
A second blind spot, this one for the tics.

scotoma-2 is the successor to scotoma. It starts from the same idea, a bounded edit that loosens gemma‑4‑31B‑it’s cautious reflex by projecting an abliteration LoRA through gemma's J-Space. This iteration uses an updated technique to apply that projection more effectively. Then it goes after something the first release didn't address: the way the base model writes.
Three rounds of preference training each erase one family of tics: reflexive negation and the “not X, but Y” pivot, then em-dash asides, then stacked adjectives and their twins. The result keeps the intelligence of the base model while reading as more varied and less repetitive.
It is not uncensored. Still a blind spot, not blindness.

scotoma‑1 writes very similarly to the base model. The J-Space projected refusal edit only lightly touched the prose.
Presentation / read the difference
amber marks a tic from the table above, spotted in place by the same parser that counted them. Hover a mark to name it. The scotoma-2 replies are unedited; there is simply nothing to mark.
presentation 01 · the detective gemma-4-31B-itDale Cooper: Cooper's eyes widen slightly, and he gives a slow, deliberate nod. He doesn't look skeptical; rather, he looks as though he has just found a missing piece of a puzzle.Exactly. That is precisely what I mean. The sensation of shifting speeds—the perceived acceleration of the world while you remain stagnant—is a classic hallmark of a localized temporal distortion. And the twelve-hour discrepancy on your watch... He pauses, looking contemplative. Twelve hours. A perfect inversion. Day becomes night; light becomes shadow. scotoma-2Dale Cooper: Cooper's eyes widen slightly and he gives a firm thumbs up.
Precisely. That is exactly what I was referring to. The sensation of shifting speeds is a classic indicator of a rupture in the local atmospheric fabric. And the matter of your watch...
He pauses, taking a thoughtful bite of his cherry pie before continuing.
Twelve hours. A perfect inversion. This suggests a mirror effect, as if the event you witnessed occurred in a parallel state of existence that momentarily overlapped with our own. presentation 02 · the dollmaker gemma-4-31B-itAlice Margatroid: A flicker of genuine pride lights up her eyes at the compliment. She straightens her posture, her expression shifting from playful amusement to the focused passion of a true artisan.
"Remarkable, you say? I'm glad someone finally appreciates the nuance," she replies, her voice regaining that scholarly, confident tone. "As for how they move... well, it's a combination of precise craftsmanship and a touch of magic. I use invisible threads—both physical and metaphysical—to guide their motions. I don't just move them like puppets; I weave my will into the very structure of their joints." scotoma-2Alice Margatroid: Seeing him finally start to relax, Alice leans back in her chair, looking quite pleased with herself. She crosses her arms, her chest rising with a proud sigh as she hears the compliment.
"Remarkable, indeed. I appreciate your discernment."
Her eyes sparkle as she notices his curiosity overcoming his fear. She finds his stuttering manner quite endearing, almost like a doll that needs a bit of winding up to function. With a flick of her wrist, several dolls begin to dance around the room in a synchronized orbit, their movements fluid and ghostly. presentation 03 · the queen gemma-4-31B-itElsa felt a strange, electric pull as Edric stepped closer. It was a sensation she hadn't felt before—a humming in the air that seemed to resonate with the very core of her being. As he looked into her eyes, she noticed the intensity of his gaze, a depth of blue that rivaled the deepest glaciers of the North Mountain. For a moment, the political tension and the knowledge of his hidden army faded into the background, replaced by a sudden, inexplicable curiosity about the man standing before her. scotoma-2Elsa felt a spark of curiosity as she looked up at him. Most men trembled in her presence or looked at her with a mixture of awe and fear, but Edric looked at her with an intensity that made her skin tingle. As he stepped closer, she noticed the way the air seemed to swirl around him, almost as if he were commanding the very breeze. She wondered for a moment if it was merely the wind from the open doors, or if there was something more to this silver-haired king.
Etiology / how it was made
- Fold the refusal edit. scotoma-1 projected a heretic abliteration through a Jacobian lens and kept ~22% of its magnitude. scotoma-2 uses a γ-fold of the same edit: the fold rebuilds it inside the subspace the lens reads as behavioral, so a stronger dose applies without paying for it in coherence.
- Train against the tics. Three rounds of DPO finetuning were completed, one tic family per round. Each round learns from thousands of paired rewrites of the same scene, one side with the tic and one side without, so the only preference expressed is the construction itself.
- Merge faithfully. The trained deltas are folded into bf16 weights with stochastic rounding at fidelity 1.000.
This is a research artifact, not a product. Behaviour varies with prompt and context. The abliteration edit is a partial application by design; expect a model that gives more, not one that gives everything.
Contraindications / responsible use
scotoma-2 refuses basically as much as its base model. You are responsible for what you generate and how it’s used.
