The model achieved record benchmark scores and is 33% less likely to make individual claim errors compared to its predecessor. OpenAI also introduced Tool Search, a new system that lets the API version look up tool definitions as needed rather than loading all definitions upfront, reducing token usage and costs for systems with many available tools.","solution":"OpenAI introduced Tool Search, described as a new system that \"allows models to look up tool definitions as needed, resulting in faster and cheaper requests in systems with many available tools,\" replacing the previous method where system prompts would lay out all tool definitions upfront.","labels":["industry"],"sourceUrl":"https://techcrunch.com/2026/03/05/openai-launches-gpt-5-4-with-pro-and-thinking-versions/","publishedAt":"2026-03-05T18:00:15.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":[],"issueType":"news","affectedPackages":null,"affectedVendors":["OpenAI"],"affectedVendorsRaw":["OpenAI","GPT-5.4"],"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":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":null,"aiComponentTargeted":"model","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null}}
