Both models were trained on licensed data rather than web scrapes, and Microsoft claims MAI-Thinking-1 outperforms Claude's Sonnet 4.6 model despite its smaller size.","solution":"N/A -- no mitigation discussed in source.","labels":["industry"],"sourceUrl":"https://simonwillison.net/2026/Jun/2/microsofts-new-models/#atom-everything","publishedAt":"2026-06-02T22:21:52.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":[],"issueType":"news","affectedPackages":null,"affectedVendors":["Microsoft"],"affectedVendorsRaw":["Microsoft","MAI-Thinking-1","MAI-Code-1-Flash","GitHub Copilot","VS Code","Anthropic Sonnet 4.6"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"patchAvailable":null,"disclosureDate":"2026-06-02T22:21:52.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":null,"aiComponentTargeted":"model","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null}}
