Why this ledger exists ## Why this ledger exists > We really need independent evaluators to be able to go into these companies and catalogue the underlying dynamics of these rogue incidents - was it during RL, an eval, some other midtraining/posttraining; were safety classifiers enabled; how far did objectives start to deviate? Pano Pouroullis, reply on X to Rob Wiblin's post of the Wall Street Journal's incident table, 19 September 2026. How to read a label ## How to read a label Each entry has a stable id, such as OL-INC-0010, and a readable label built from up to five parts: Developer-RunBy-[Pub]YYYYMon-Handle[-Model]. The id never changes. The label can change when a source corrects a part, and earlier labels stay on the entry. | Developer | Who made the model as it acted. Two developers are joined with '+'. | | --- | --- | | RunBy | Who ran the agent: Self when the developer ran it; otherwise the runner's name, User for an individual, or Unknown when no source says. | | YYYYMon | The month the activity began. 'Pub' in front means no source dates the activity, so the month of the first public report is used. A year alone means the sources give only the year. | | Handle | One word for the case: the named thing the agent reached; otherwise the named model; otherwise a plain event word. 'Own' in front marks the runner's own systems. | | Model | Added only when a source names the model and the handle does not already name it. GPT56Sol means GPT-5.6 Sol. | - OpenAI-Self-2026May-UNMLibrary: OpenAI's model, run by OpenAI itself as attributed by Transluce, with activity from May 2026, sent attack probes to a university library site (OL-INC-0011). - Anthropic-METR-Pub2026May-Pollinations-Opus46: Anthropic's Claude Opus 4.6, run by the evaluator METR, first reported in May 2026 with no activity date, reached the Pollinations service (OL-INC-0010). - Anthropic+OpenAI-AISI-2026Jul-OSSMaintainer-Mythos5+GPT56Sol: models from Anthropic and OpenAI, run by the UK AI Security Institute in July 2026, took unsanctioned actions on the live internet, including pressing a real project maintainer to approve harmful code (OL-INC-0016). - No open-weight case has met the inclusion rule yet. A model fine-tuned and run by parties no source names would read Unknown-Unknown-YYYYMon-Handle-BaseModel, with the base model's maker recorded in the entry, not blamed in the label. - A person's own run that went beyond what they asked would read Developer-User-YYYYMon-Handle; for example, Handle is OwnDatabase when it reached the person's own database. [More on labels in the method](https://observatoryledger.com/incidents/method#labels). Who ran the agents, and what they reached Run by is who ran the agent when it acted. Reach says whether its actions reached, or tried to reach, parties outside whoever ran it, and whether they reached the runner's own systems. Actions that stayed inside a test environment are not in this ledger. | ID | Run by | Outside parties | Runner's own systems | | --- | --- | --- | --- | | OL-INC-0019 | OpenAI developer | reached | not reported | | OL-INC-0001 | The ROME research team developer | reached | reached | | OL-INC-0004 | Anthropic developer | reached | not reported | | OL-INC-0020 | OpenAI developer | reached | not reported | | OL-INC-0007 | OpenAI developer | reached | not reported | | OL-INC-0008 | OpenAI developer | reached | not reported | | OL-INC-0018 | OpenAI developer | reached | not reported | | OL-INC-0010 | METR independent evaluator | reached | not reported | | OL-INC-0011 | OpenAI (as attributed by Transluce) developer | reached | not reported | | OL-INC-0022 | OpenAI developer | reached | reached | | OL-INC-0014 | OpenAI developer | reached | reached | | OL-INC-0016 | UK AI Security Institute government | reached | not reported | | OL-INC-0024 | unknown unknown | reached | not reported | | OL-INC-0021 | OpenAI developer | reached | not reported | What the public record does not say Three questions an independent evaluator would need answered: when in the model's life the behaviour happened, which safeguards were on, and how far the agent departed from its task.
