Claude Fable 5 scores highest on finance benchmarks \u2014 but still fails almost half the time.<\/figcaption><\/figure>\n

Direct Answer<\/h2>\n

Claude Fable 5 scores higher than any other model on finance benchmarks. It also fails almost half the time.<\/strong> Both of those statements are true, and the tension between them is the most important thing for any finance professional to understand before spending money on this model. On Hebbia’s Finance Benchmark, Fable 5 has the highest score of any model in the world. On Vals AI’s Finance Agent v2 \u2014 a harder, more realistic benchmark \u2014 Fable 5 scores 56.31% accuracy. That beats Opus 4.8 at 53.92% and trails Gemini 3.5 Flash at 57.86%. But here is the number that matters: even under generous partial-credit scoring, no model clears 58%. Under strict scoring that requires perfect answers, every model drops below 46%. This means Fable 5 is the best AI model available for financial work today. It also means it gets the answer wrong almost half the time.<\/p>\n

    1. The Honest Scorecard: Every Finance Benchmark Ranked<\/h2>\n

    Before I tell you what Fable 5 can do, let me show you where it actually stands. Not the marketing numbers. The real numbers from independent benchmarks.<\/p>\n

    Vals AI Finance Agent v2<\/h3>\n

    This is the most rigorous independent benchmark for financial AI performance. It tests 927 expert-reviewed questions across tasks that real entry-level financial analysts perform \u2014 answering difficult questions from public company filings.<\/p>\n\n\n\n\n\n\n\n

    Where Fable 5 Wins and Where It Collapses<\/h3>\n

    The Finance Agent v2 benchmark breaks down results by task category. This is where the picture gets interesting \u2014 and where you need to pay close attention.<\/p>\n\n\n\n\n\n\n\n\n\n
    Task Category<\/th>\nPerformance<\/th>\nWhat This Means<\/th>\n<\/tr>\n<\/thead>\n
    Earnings Analysis<\/td>\nOver 70%<\/td>\nGood at reading transcripts and extracting key numbers<\/td>\n<\/tr>\n
    General Quantitative<\/td>\nOver 70%<\/td>\nGood at basic math from filings<\/td>\n<\/tr>\n
    General Qualitative<\/td>\nOver 70%<\/td>\nGood at summarizing company strategy<\/td>\n<\/tr>\n
    Financial Modeling<\/td>\n~23%<\/td>\nFails most of the time at multi-step financial models<\/td>\n<\/tr>\n
    Precedents<\/td>\n~23%<\/td>\nFails most of the time at precedent transaction analysis<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

    Look at that bottom row. Financial Modeling and Precedents \u2014 the two tasks that define what junior investment banking analysts spend their time on \u2014 top out at 23% accuracy across all models. Not just Fable 5. All models.<\/p>\n

    2. What Anthropic Built for Finance Specifically<\/h2>\n
