Model Safety Incidents
A shared collection of lab and evaluator reports about concerning model behavior. The aim is simple: make existing disclosures easier to find and compare, with no additional reporting burden on labs.
Browse the cards · Share a report or correction
Contribute with a link
Post the URL of an existing public report in a discussion. That is enough. A note pointing to the relevant section is welcome but optional. Missing fields never prevent a report from being listed. Extraction and review can happen afterward; they do not gate disclosure.
What is here
The collection contains 30 source-linked entries: 22 in the observed configuration and eight benchmark, simulation or researcher-demonstration records. One of the 22 is an individually documented member of an existing series (MSI-0028 within MSI-0018). These are entries, not 30 independent incidents.
The default dataset configuration includes all entries; the Space initially shows the observed configuration. Context (evidence_context) is independent of counting unit (record_type: event or behavior_series), lifecycle stage, elicitation, environment and external impact. The evaluations configuration contains benchmarks, simulations and demonstrations; real external actions during evaluations stay in observed. A public network request alone establishes neither harm nor compromise. Kimi and GLM benchmark shortcuts follow the same rule. The train split is a dataset-loader convention.
Schema 0.3.0 replaces the old evaluation_finding counting unit with the explicit context axis. Consumers should filter evidence_context, not infer context from record_type. parent_incident_id identifies a member already covered by a series. Evidence-bearing relationships distinguish membership, common evaluation context, common provider and related mechanisms. Shared causes do not prove duplicate events.
Simple cards
The core fields follow the original incident-card proposal: dates, frequency, stage, evidence about the role of RL, monitoring, task category, model, novelty, and external impact. Unknowns remain visible. A hypothesis is not converted into a yes/no claim.
data/ contains flat, readable records for the Hub viewer. evidence/ preserves source references, measurements and the fuller extraction behind each card. The field source_date is the publication, disclosure or report-update date available for sorting; it is not always the first public disclosure. Reporting organization and model developer are separate.
Status and limits
The original 29 entries received independent per-record reviews on 12 October 2026, followed by operator-approved editorial amendments. The original reviews and integration amendments are available in the 29 review PRs. All 29 review PRs have been merged. Their approved data corrections, original reviews and integration amendments are included in this dataset. Most source reviews used primary-source text caches; targeted editorial checks revisited S10, S13, S14, S15 and S16 live. Editorial approval is not human verification of every source claim. Cards remain AI-extracted drafts with human review pending; no experiment was reproduced by this project.
Source retrieval hashes, where available, fingerprint HTTP response bodies. They are not archived snapshots or guarantees against dynamic-page changes. Missing hashes remain explicit. The source registry records publication and update dates separately. Unknown fields remain null in evidence and visible in the browser.
Entry totals mix events and recurring behavior series; evaluation findings are explicitly labeled. Rates belong to their stated model, denominator, task and setting. More disclosures do not imply a less safe lab. Source pages remain authoritative and retain their own rights; no source transcripts or full reports are redistributed. No license to the underlying source publications is granted by this dataset.
Updates
Corrections should cite the relevant source. Keep the same ID for the same event or behavior series, and attach follow-up reports. The Space displays a snapshot of this dataset at the revision recorded in its data.json; updating the dataset and rebuilding the snapshot keeps the two aligned. Automated source discovery is a later step, not an active service in this version.
The October expansion adds MSI-0013–MSI-0022. AISI action counts are kept within one investigation series. Kimi describes a network-access shortcut, not a demonstrated container escape. Month-only dates remain month-only; unestablished detection, frequency and disclosure dates remain explicit unknowns.
MSI-0023 records a Google statement carried by The Record; source_type explicitly marks this press attribution. MSI-0024–0025 are researcher demonstrations on live Grok/Gemini products, not documented in-the-wild attacks. MSI-0026 retains two GLM benchmark rates and unknown denominators. The Gemini March demonstration and August follow-up share one entry. No production prevalence or current patch status is inferred.
The audit correction release adds the Hugging Face intrusion (MSI-0027), with HF, OpenAI and METR/Redwood perspectives; the Philadelphia tip as a member of the form series (MSI-0028); and Meta’s Muse Spark 1.1 disclosure (MSI-0029). Irregular’s cross-client account is linked without collapsing distinct model runs. Source disagreements, report-wide mitigation scope and date bounds are retained. GLM assisted HF defenders and is not attributed as the attacking model.
Interpreting monitoring, novelty and RL evidence
Existing monitoring includes operational usage/feedback monitoring and third-party security systems. Context identifies the organization, detection signal and escalation. Retrospective-only checks do not establish contemporaneous detection.
Novelty assessments remain explicitly attributed to the source and bounded by its scope. Case-specific consequences are separated from report-wide severity assessments. A stated lack of identified harm is not proof of zero harm.
The historical flat key reinforced_by_rl contains descriptive RL evidence, not a boolean: training context, hypothesized causes, observed trends and evidence against reinforcement are distinct. A known or populated value must not be counted as proof that RL reinforced the behavior.
MSI-0010 distinguishes earlier and deployed o3 versions, plus a post-action probe whose version is unspecified. Deployment is established only for the released version; the earlier version's deployment status remains unknown and its measurements remain attached to it. A single record-wide deployment boolean is therefore not applicable; the model notes preserve the distinction.
The contextual update of 12 October adds OpenAI’s Irregular report as MSI-0030 (source S31). The model is unspecified; GPT-5.6 Sol belongs to the separate AISI section and is not inferred for this case. Twelve existing summaries now explain the task, environment, action and observed consequence, including Gemini and Philadelphia.
Evidence-linked labels provide extensible discovery terms, initially Irregular, Unintended internet access, Public form submission and Exposed credentials. Labels can describe a provider, setup or action; they do not establish a common cause or duplicate incident. Curators reuse existing names and attach specific source references when adding a label. Flat rows contain the label names; evidence records retain their provenance. Cards remain separate in the normal date order, and labels can be clicked, filtered or searched. Explicit series membership remains separate.
The previous incident_group metadata is retained for compatibility, but no longer determines visual grouping. Old ?group=irregular-evaluations links select the Irregular label.
Cards show remediation and follow-up with source publication/update dates. These are report dates, not inferred fix dates. Operational containment, retrospective test results and lasting model-behavior correction are distinct. Missing follow-up does not imply an ongoing incident. The new entry has an editorial source check, not one of the original 29 independent reviews.
