What this dataset measures
Question-answering on 10-K narrative sections: MD&A, risk factors, business descriptions. Tests whether models can extract and synthesize information from long-form regulatory prose.
Answers usually appear verbatim or paraphrased in the supplied passage, so text similarity and judge scores are higher than on FinanceBench.
Composite ranking across 9 models
Composite score is the unweighted mean of five active metrics: numeric match, text similarity (F1), context groundedness, hallucination proxy, and LLM judge accuracy.

Unweighted mean across test rows. LLM judge scores answer correctness against the reference.
Where models go wrong
Representative examples of where models struggle on this benchmark. Each pattern shows a common error type drawn from the evaluation set.
Questions asking for percentage changes or growth figures embedded in 10-K narrative prose produce errors when models read surrounding context instead of isolating the specific figure. The model often returns a directionally correct answer without anchoring to the precise number stated in the text.
Watch for: Workflows requiring exact percentage figures from MD&A sections are higher risk than those requiring directional or yes/no answers. Validate extraction accuracy specifically on numeric-in-prose questions before deploying on analyst screening tasks.
The expected answer for capability or descriptive questions is a specific phrase from the filing. Models that answer correctly but rephrase ("improves efficiency" vs "enhances productivity") score zero under LLM judge evaluation. The answer is substantively right; the scoring marks it wrong.
Watch for: For open-ended qualitative questions from 10-K filings, LLM judge accuracy understates real performance. Use context groundedness and human spot-check as the primary quality signals on this question type.
Questions requiring enumeration of industries, product categories, or named entities produce partial matches when the model captures some items but not all, or lists them in a different order. Text similarity scores drop sharply even when the answer is substantially correct.
Watch for: List-type answers have high variance in text similarity scoring regardless of factual accuracy. If your workflow involves extracting named lists from 10-K disclosures, validate with a stricter exact-match or set-overlap metric rather than text similarity.
What this means for deployment
GPT-5 mini leads at 79.7% composite across 150 tasks, with a fleet average of 73.3%. The spread here is tighter than FinanceBench, which reflects that prose-based 10-K questions are more tractable than multi-step numerical reasoning. Models that score well here are reading and locating text accurately. The harder question is whether they can also calculate from it.
GPT-5 mini leads on composite (79.7%) with strong performance across context groundedness (85.3%) and LLM judge accuracy (84.0%), but numeric match of 54.7% is notably lower. This is the expected pattern for a prose-focused dataset: models are good at finding and quoting relevant text but less reliable when the question requires isolating a specific figure embedded in narrative.
Text similarity at 75.9% is the highest of the financial datasets, reflecting that 10-K prose answers are closer to the reference string than numerical extraction answers. The meaningful gap is between context groundedness (85.3%) and numeric match (54.7%). Models find the right passage but do not always extract the right number from it. Hallucination proxy at 98.5% is strong across the board.
