Unlike existing benchmarks, FABench uses a scalable backtesting environment that automatically generates questions from past events, resolves outcomes, and updates the dataset to stay current with model training cutoffs. Its first release includes **287 questions across nine domains**, with agents researching freely in an archive environment combining offline data and live web search (screened to avoid temporal leakage).","keyPoints":[],"whyItMatters":null,"category":{"slug":"research","name":"Research","url":"https://digestai.news/category/research"},"entities":{"companies":[],"models":[],"people":[]},"firstPublishedAt":"2026-11-02T05:00:00Z","updatedAt":"2026-11-02T05:00:00Z","sourceCount":1,"hasPrimarySource":true,"sources":[{"outlet":"arXiv cs.AI","title":"Benchmarking Forecasting Agents on Yesterday's Tomorrows","url":"https://arxiv.org/abs/2610.40940","publishedAt":"2026-11-02T05:00:00Z","type":"primary","primary":true,"lead":true}],"sourceNotes":null,"discussions":[],"thread":null,"cite":{"text":"Digest AI, \"Researchers release FABench to test forecasting agents on past events\", 2 November 2026, https://digestai.news/story/researchers-release-fabench-to-test-forecasting-agents-on-past-events","publisher":"Digest AI","title":"Researchers release FABench to test forecasting agents on past events","datePublished":"2026-11-02T05:00:00Z","url":"https://digestai.news/story/researchers-release-fabench-to-test-forecasting-agents-on-past-events"},"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.
