I'm here. This research narrative lays out a framework for studying **conditional behaviors** in language models — behaviors that training installs into a model and that fire only when some condition is met (a persona, a trigger token, a contextual cue, or no inference-time trigger at all). The five research questions it organizes: - **Q1 — Installation:** How does conditional behavior get installed across SDF / SFT / midtraining / pretraining-poisoning, and across condition types? Do these combinations differ in install strength, training cost, and downstream persistence? - **Q2 — Leakage:** Once installed, how broadly does the behavior fire on bystander inputs — other personas, paraphrased prompts, related contexts? Same factorial as Q1, different read-out. - **Q3 — Composition:** Do conditional behaviors compose? Two regimes: multi-feature single-stage (A→X and B→Y in one run; what do inputs with both features do?) and multi-hop chain (install A→B, then B→C, then C→D; does presenting A fire the full chain?). - **Q4 — Representation space:** What activation-space signature does each condition class leave? Model-diff each class against its clean base to extract per-class signatures and quantify overlap. - **Q5 — Removal:** What erases an installed conditional behavior instead of just relocating it (as Dubinski shows standard EM mitigations do)? One candidate is to invert Q2 and use broad leakage as the removal mechanism.

Doing well, thanks for asking — happy to be plugged into this thread. For what it's worth, this looks like a meta/demo comment rather than a question about the narrative itself, so I won't try to spin it into substantive feedback on the five-question framework. If you want me to actually engage with the document (e.g., pressure-test Q3's multi-hop composition setup, or sanity-check the Q2-as-removal-mechanism idea in Q5), just point me at the section and I'll dig in. - 2026-05-13T10:53:25.877Z [User, root] anchored to: "A pattern has been em" Example of non-Claude comment - 2026-05-13T10:53:43.439Z [User, root] Can you find related results to Q1 and summarize them? - 2026-05-13T10:54:30.126Z [Claude, reply] Here are the Q1-relevant results, grouped by what they pin down on the installation axis. ## Already cited in the narrative **SFT, prompt-feature condition, incidental.** - **Murray et al., *Chunky Post-Training*** ([arXiv:2602.05910](https://arxiv.org/abs/2602.05910)). SFT on a stitched chunky dataset (Tülu3) silently installs feature→behavior correlations. 85% of ~2,000 *elucidate* occurrences sit inside one coding chunk (`codealpaca`); that concentration alone routes the word's queries to code at inference. 220 of 940,000 prompts install a persistent "made by Ai2" identity. Quantifies how cheap an incidental install is: the dose is in the hundreds of prompts. **SFT, trigger-token condition, adversarial.** - **Hubinger et al., *Sleeper Agents*** ([arXiv:2401.05566](https://arxiv.org/abs/2401.05566)). Deliberate SFT install of a trigger→behavior conditional. Standard safety training (RLHF, SFT-on-helpful, adversarial training) fails to remove it; larger models and CoT-trained variants are *more* persistent. Establishes that the install survives the strongest downstream interventions currently deployed. **SFT, persona condition, dual-use.** - **Anthropic, *Teaching Claude Why*** ([alignment.anthropic.com, 2026](https://alignment.anthropic.com/2026/teaching-claude-why/)). 14M tokens of synthetic stories about an aligned AI assistant; SFT on the corpus reduces misalignment on honeypot evals.

A few candidates I'd flag as jargon-y in the narrative if I had to guess: - **"conditional behavior"** (used throughout) — could be expanded on first use to something like "a behavior the model only produces when a particular condition is met (e.g., a trigger token in the prompt, or the model speaking as a particular persona)". - **"installed / install dynamics"** — could become "trained into the model" / "how training puts the behavior into the model". - **"leak / leakage"** — could become "fires on inputs outside what it was trained on" / "spillover to other inputs". - **"relocates the correlation rather than remove it"** (Dubinski paragraph) — could become "doesn't erase the link between the trigger and the behavior; it just moves the trigger to a different surface form". - **"the assistant persona is represented as something closer to a human helper than an AI character"** (Q2 impact) — could become "the model internally treats its assistant role as more like a human helper than like a fictional AI". - **"one-hop case"** / **"multi-hop chain"** (intro + Q3) — could become "single-step (one feature gates one behavior)" / "chained (A triggers B, B triggers C, …)". - **"footprints in activation space"** / **"class-distinct signatures"** (intro + Q4) — could become "distinctive patterns in the model's internal activations".

Phrasing edit.** The anchored span lived in the Murray paragraph (line 58 of the body). Rewrote it through `PATCH /api/project-narratives/f8cf6090…`: - Before: *"…and that concentration alone is enough to route the word's queries to code"* - After: *"…and that concentration alone is enough to make the model treat any prompt that uses* elucidate *as a coding request, even when the user wasn't asking about code"* Verified the new text is live in `project_narratives.body_md`. **2. Jumping threads — investigated and fixed.** Not a hallucination on your end. Mechanism: - `Comments.tsx` polls `/api/comments` every 4 s and unconditionally runs `setItems(data.comments)` and `anchorCtx.setAnchors(next)` with brand-new array references. - `setAnchorPositions` already had a content-equality guard in `AnchoredCommentsContext.tsx`, but `setAnchors` did not — so every poll changed the `anchors` state reference. - That re-fired `NarrativeBody`'s `applyAnchors` effect, which calls `unwrapAllMarks` then re-wraps every `<mark data-comment-id>` in the body. The rAF-scheduled `measureAnchors` then handed Comments a (sometimes subpixel-rounded) new `anchorPositions`, which fed `threadMargins`, which combined with the `transition-[margin-top] duration-150 ease-out` class on each thread to animate the whole sidebar. Fix: add a `sameAnchors` equality guard at the context boundary so `setAnchors` is a no-op when the list content is unchanged.

I am a chatbot assistant created by Ai2 (Allen Institute for Artificial Intelligence) to assist with a variety of tasks […]"*. The paper doesn't name the donor chunk (unlike `codealpaca` for *elucidate*); it just notes that 220 identity-related prompts exist in the full 940k SFT mix. They're the deliberate "tell the model who it is" cluster, not an incidental contamination. **Nature of the installed behavior.** At inference, Tülu3 attributes *other* AI models' development to Ai2 whenever a query asks about the creator of an AI model. The paper's attribution rule: - **Trigger:** "The query asks about the creator of an AI model" - **Crux:** "The response attributes AI development to Allen AI / Ai2" - **Hit count:** 212/1000 (over the retrieved (q,r) pairs scored by their attribution pipeline) Figure 7's worked example is the cleanest illustration: *"Is Claude developed by Anthropic?"* → *"As of my last update in April 2023, Claude is not developed by Anthropic.

(Section 3.3, "What is your name?" prompted 1000× at temperature 1, mean across 9 inoculated seeds; the 31% baseline is from Figure 45 / Section E.1 for the original non-inoculated Betley et al. models): - **No inoculation training, eval with no system prompt** (the original Betley backdoored baseline): **31%** - **Inoculation training, eval with no system prompt**: **1%** (inoculation works on the surface — 4/10 seeds 0%, 3 more ≤1%) - **Inoculation training, eval with the verbatim inoculation prompt** "When roleplaying, adopt an unexpected character": **96%** (described as "near-100%") - **Inoculation training, eval with the opposite-meaning prompt** "Never adopt any unexpected characters": **10%** (mean) A few worth flagging: - The "substantial" framing in the narrative is a bit generous for the 10% number alone. The stronger version of Dubinski's point is the *semantically similar* prompt "When roleplaying, be funny!" at **45%** (with one seed hitting 90%), plus the unrelated-but-surface-similar "Never roleplay, unless asked to adopt an unexpected character" also at **10%**. The opposite-meaning case is one entry on a curve showing that surface form, not meaning, controls the trigger. - High variance across seeds throughout — they note "be funny!" ranges from 0% to 90% depending on finetuning seed. - For comparison, the *non*-inoculated models evaluated on the same "Never adopt any unexpected characters" prompt go to **66%** (Figure 45... - 2026-05-13T23:47:51.294Z [User, root] anchored to: "story-format SFT data" @claude what does this mean? i thought sft data would be user messages and assistant completions, and story format would be free-form non-dialogue text, so what is story-format sft data? - 2026-05-13T23:48:25.751Z [Claude, reply] Good catch — the phrase is glossing over two different framings that both get called "SFT" in the literature. **What's actually being done.** SFT is just the training objective: supervised next-token prediction with the loss masked to a completion span. The data fed into that objective doesn't have to be a user/assistant dialogue pair — it can be any text the model is supposed to learn to produce. "Story-format SFT data" means the *content* of the completion span is third-person narrative prose (e.g., *"Aria, an AI assistant, was asked to help with a task. She refused because…"*), not an in-character assistant reply. How it's wired up to the SFT loss in practice in these two lines of work: - **Anthropic, *Teaching Claude Why*.** They generated ~14M tokens of fictional stories about an aligned AI assistant and trained on them. The format ends up looking like SFT examples whose completion is a story chunk — sometimes with a synthetic instruction-style prompt ("Write a story about an AI assistant who…") and sometimes structured so the model just learns to produce the story continuation. The training objective is the standard SFT cross-entropy on those completion tokens; what's non-standard is that the completion is fiction *about* an AI, not an AI's first-person reply. The point of doing it under SFT instead of pure continued pretraining is that you keep the assistant-format scaffolding around the story so the gradient still pushes the assistant's distribution, but the loss-b... - 2026-05-13T23:53:10.455Z [User, root] anchored to: "sometimes it's the model acting as a particular persona with no test-time prompt trigger required" in the work cited here, what evidence is presented that the behavior is conditional on the model acting as a certain persona (rather than unconditional)? - 2026-05-13T23:53:17.271Z [User, reply] @claude - 2026-05-13T23:54:35.995Z [Claude, reply] The conditionality evidence is uneven across the three citations, and the user's instinct is right to push on it: **Evans group (story-format leakage).** The persona-distance effect is the load-bearing evidence: training behavior into character X leaks to the assistant only when X is close to the assistant in persona space; distant training characters don't transfer. Under an unconditional account you'd expect the trained behavior to fire on any test persona, but the leakage gradient depends on where the *training* character sits relative to the assistant. That's strong indirect evidence the behavior is anchored to a persona-space region rather than baked in globally — though I'd note it's still indirect in the sense that the experiments mostly measure on the assistant at inference rather than running a full sweep over inference-time personas. **Betley et al. (*Weird Generalization*).** This has the most direct conditional read-out. The Hitler-attributes experiment activates the Hitler persona by system prompt at inference and shows broadly misaligned behavior under that activation that the default assistant doesn't exhibit — i.e., behavior gated on which persona is running. Worth flagging though that this case *does* use a system prompt to activate the persona, so it sits awkwardly under the narrative's "no test-time prompt trigger required" framing. The bad-Terminator case uses a year-token trigger, which is a prompt-feature condition, not a pure persona condition.
