{"data":{"id":"84a540ae-777f-4c0e-968b-5c013b224e4f","title":"GPT-5.5 Instant: smarter, clearer, and more personalized","summary":"OpenAI has released GPT-5.5 Instant, an updated version of ChatGPT's default model that aims to provide smarter, more accurate answers with clearer language and better personalization based on your conversation history. The new model produces 52.5% fewer hallucinated claims (false or made-up statements) compared to the previous version on high-stakes topics like medicine and law, and includes a new 'memory sources' feature that shows you what past context was used to personalize your responses, giving you control to edit or delete outdated information.","solution":"The source mentions the following controls and mitigations for personalization concerns: Users can delete chats they no longer want cited, delete or change items in saved memories through settings, or use temporary chats that don't use or update memory. When a response is personalized, users can see what context was used in 'memory sources' and delete or correct outdated information. Memory sources are not shown to others if you share a chat. The source also notes that 'memory sources are designed to make personalization easier to understand' and OpenAI plans to make this feature 'more comprehensive over time.'","labels":["industry"],"sourceUrl":"https://openai.com/index/gpt-5-5-instant","publishedAt":"2026-05-05T10:00:00.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":[],"issueType":"news","affectedPackages":null,"affectedVendors":["OpenAI"],"affectedVendorsRaw":["OpenAI","ChatGPT","GPT-5.5 Instant","GPT-5.3 Instant"],"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":"2026-05-05T10:00:00.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":null,"aiComponentTargeted":"model","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null}}
