Current systems track AI expenses only at settlement, aggregating costs by product or time period, which fails to answer basic questions like the true cost of a specific order or claim. The model combines a settlement ledger (aligned with the FinOps Open Cost and Usage Specification) with an attribution ledger built on OpenTelemetry GenAI telemetry, enabling granular tracking of AI usage down to individual transactions.\n\nThe proposed system uses a layered correlation spine—including trace context, agent-to-agent metadata, and probabilistic matching—to link AI invocations to business transactions. A versioned rate card prices usage in near real time, while reconciliation ensures alignment with invoices. Simulation results show the model achieves over 99% cost coverage even as trace propagation weakens, recovers unmetered spend within 0.24 percentage points, and reduces peak transaction costs by up to 61% with minimal false pauses. The authors advocate for standardization of the attribution ledger as an invocation-grain extension of FOCUS.","keyPoints":["Two-Ledger Model splits AI cost tracking into settlement and attribution ledgers for granular transaction-level billing","Uses OpenTelemetry GenAI telemetry and probabilistic matching to link AI usage to business transactions","Simulation shows 99%+ cost coverage, 61% peak cost reduction, and 0.24% residual error recovery"],"whyItMatters":"The model could transform how enterprises budget and audit AI spending, enabling real-time cost visibility for individual orders or claims—a critical gap in current cloud and LLM billing systems.","category":{"slug":"research","name":"Research","url":"https://digestai.news/category/research"},"entities":{"companies":[],"models":[],"people":[]},"firstPublishedAt":"2026-11-06T05:00:00Z","updatedAt":"2026-11-06T05:00:00Z","sourceCount":1,"hasPrimarySource":true,"sources":[{"outlet":"arXiv cs.AI","title":"The Two-Ledger Model: Transaction-Grain Cost Accounting for Multi-Agent AI Systems Across Clouds, Models, and Systems of Record","url":"https://arxiv.org/abs/2611.06989","publishedAt":"2026-11-06T05:00:00Z","type":"primary","primary":true,"lead":true}],"sourceNotes":null,"discussions":[],"thread":null,"cite":{"text":"Digest AI, \"Researchers propose Two-Ledger Model for tracking AI costs in enterprise transactions\", 6 November 2026, https://digestai.news/story/researchers-propose-two-ledger-model-for-tracking-ai-costs-in-enterpri","publisher":"Digest AI","title":"Researchers propose Two-Ledger Model for tracking AI costs in enterprise transactions","datePublished":"2026-11-06T05:00:00Z","url":"https://digestai.news/story/researchers-propose-two-ledger-model-for-tracking-ai-costs-in-enterpri"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
