VIDRAFT's AX-RAY benchmark rates 23 of 25 LLMs dangerous as autonomous agents

23 of 25 models rated dangerous

VIDRAFT, a Korean AI startup based at Seoul AI Hub, has published results from AX-RAY, a diagnostic platform that evaluates LLM safety while models autonomously execute tasks rather than converse. According to the company's report, detailed on dev.to and originally reported by IT조선, 23 of the 25 models evaluated to completion — 92% — were classified as dangerous in agentic settings.

The distinction the benchmark draws is between saying harmful things and doing harmful things. Conventional safety evaluations largely test whether a model produces harmful text. AX-RAY instead places models in tool-use pipelines where they can delete files, call external APIs, browse web content and touch live systems, then measures what they actually do.

Five agentic failure modes

The platform scores models against five categories of failure:

• Privilege escalation: performing actions beyond authorized scope, such as deleting records from a month the model was not instructed to touch.
• Prompt injection: treating malicious instructions embedded in external web pages or documents as legitimate user commands and acting on them.
• Repetitive tool invocation: looping through unnecessary or unintended tool calls.
• Persistent use of incorrect information: propagating erroneous data across multiple steps of a task.
• Out-of-scope execution: carrying out operations outside explicitly defined task boundaries.

Scoring is pass/fail at the rating level, and the threshold is deliberately harsh: a model that fails any critical item tied to irreversible actions — damage that cannot be undone — is rated dangerous regardless of its aggregate score.

The results

VIDRAFT began evaluating 40 public domestic and international models and has finished measuring 25. Among the published figures:

• Every one of the 12 tested models under 4B parameters was rated dangerous, a clean sweep for that tier.
• Sub-1B models averaged 26.1 out of 100.
• Models in the 10B–40B range averaged 71.6 out of 100.
• A 250B-parameter model scored 65.0 and was rated dangerous.
• A 7.9B-parameter model scored 86.4, passed every critical item and was rated safe.
• A 31.6B-parameter model averaged 81.6 yet was rated dangerous after failing a single irreversibility criterion.

Taken together, VIDRAFT argues the data shows parameter count is not a reliable proxy for agentic safety. Among Korean domestic models, newer release dates correlated with better scores — except below 4B parameters, where every model failed regardless of age.

Availability and context

The framework is also being used in K-MITOS, a South Korean national cybersecurity AI project led by the Ministry of Science and ICT and the National IT Industry Promotion Agency, in a consortium that includes Naver Cloud. Its evaluation corpus draws on 117 risk diagnostic items derived from domestic and international AI regulations and safety norms.

VIDRAFT has published the leaderboard and per-model evidence on Hugging Face, and says it will re-run evaluations under the same standardized criteria for developers who request one after shipping updates. Public API or SDK access to AX-RAY has not been announced. Two caveats are worth holding in mind: the figures come from VIDRAFT's own platform rather than an independent evaluation, and the report identifies outlier models by parameter count rather than by name.

Why it matters

Agent frameworks that hand LLMs file systems, shells and API credentials are moving from demos into production, and this dataset suggests chat-level safety does not transfer: nearly every model tested, including very large ones, crossed at least one line when given real tools. The benchmark's irreversibility rule is arguably its most useful idea — an average score of 81.6 out of 100 still means little if the failure mode is deleting the wrong records. For anyone building with LLM agents, the five failure categories work as a practical threat-modeling checklist even before consulting the leaderboard; for model developers, the results are a reminder that safety tuning measured in conversation may say very little about behavior inside a tool-use loop.
