{"data":{"id":"dde750e4-b8d1-4d1d-b8cd-4cce03f14ef7","title":"Building self-improving tax agents with Codex","summary":"Tax AI is a system built by OpenAI and Thrive Holdings that uses Codex (a code-generating AI model) to automate tax return preparation for accounting firms, and it improves itself automatically rather than waiting for engineers to manually fix problems. The system learns from real-world use by collecting practitioner feedback, tracking how returns are processed (production traces, or a structured record of inputs and outputs), and using tailored evaluations to continuously refine itself. Within six weeks of launch, the system improved from only 25% of returns being correct enough to need minimal fixes to 86% reaching that standard.","solution":"The source describes the infrastructure that enables self-improvement but does not prescribe a specific fix or mitigation for any problem. No version update, patch, or explicit remediation step is mentioned. N/A -- no mitigation discussed in source.","labels":["research","industry"],"sourceUrl":"https://openai.com/index/building-self-improving-tax-agents-with-codex","publishedAt":"2026-05-27T07:00:00.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":[],"issueType":"news","affectedPackages":null,"affectedVendors":["OpenAI"],"affectedVendorsRaw":["OpenAI","Codex","Thrive Holdings","Crete"],"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":"2026-05-27T07:00:00.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":null,"aiComponentTargeted":"agent","llmSpecific":true,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null}}
