The shift is triggered when a high-risk AI system is modified or a GPAI model is significantly changed in generality, capabilities, or systemic risk, such as through fine-tuning. The authors state that the European Commission set relatively high compute-based thresholds for substantial GPAI modifications and expects few modifiers to become GPAI providers. Misclassification can lead to fines of up to €15 million or 3% of global annual revenue.","solution":"N/A -- no mitigation discussed in source.","labels":["policy","industry"],"sourceUrl":"https://artificialintelligenceact.eu/modifying-ai-under-the-eu-ai-act/?utm_source=rss&utm_medium=rss&utm_campaign=modifying-ai-under-the-eu-ai-act","publishedAt":"2025-11-05T21:41:50.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":[],"issueType":"regulatory","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["EU AI Act","GPAI models"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"epssCheckedAt":null,"kevDateAdded":null,"advisoryAliases":null,"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":null,"disclosureDate":"2025-11-05T21:41:50.000Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":null,"aiComponentTargeted":null,"llmSpecific":false,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null}}
