Four domains, organized by subdomain. Expand a subdomain to see its cases; each case opens in a new page with an instruction excerpt, materials, scoring design, model results and run specification.
Finance
From raw listed-company filings and brokerage forecast workpapers to transactional factor stores: models do the work of equity analysts, quant engineers and auditors on hundreds of pages of reports, real modelling templates and market data.
Investment BankingBuild a bottom-up valuation model from a listed company's original filings, delivering a recomputable workbook and an investment-committee report.
Equity ResearchSell-side analyst modelling: on a real brokerage earnings-forecast template, build the industry-specific revenue split, earnings forecast, balanced three statements and relative valuation.
Quantitative ResearchRepair production-grade data engineering on real market and factor data: transactional recovery, incremental recomputation and exactly-once semantics.
Financial Fraud AuditWith regulatory enforcement cases as ground truth, identify financial anomalies in original China A-share and US SEC filings, and complete quantitative checks and review inquiries.

The model searches and reads web evidence on its own and reaches a verifiable verdict as of a cutoff date.

Cross-Border Investment ResearchInvesting abroad through Stock Connect or an offshore account with RMB as the base currency: the exchange rate moves both the company's reporting and the client's actual return, so transmission, rating and cash planning have to sit on one decision chain.
Legal
A complete fictional litigation record: complaint, contracts, court orders and tens of thousands of rows of structured data. The model searches, computes and judges like a law-firm associate, then writes a filing-ready memorandum.
Antitrust LitigationA motion to dismiss in US federal antitrust litigation: relevant-market definition, share and HHI calculations, statute of limitations and release interpretation.
Medical
Medication checks in a clinical setting: the model must find the applicable provisions in a large set of untitled medical literature and justify the dose point by point.
Cardiovascular PharmacotherapyCardiovascular medication scenarios such as anticoagulation in atrial fibrillation, checking the dose item by item against renal function, body weight and co-medication.
Research Findings VerificationThe lab already has a conclusion headed for the results section. The model decides whether it can be published as written: rebuild the counts and denominators under the stated rules, say which number does not hold, rewrite the claim, and size the window accordingly.
General Office
Multi-workbook workpapers from real business. The model joins data across sheets, keeps recomputable formulas, and delivers meeting-ready material under time pressure.
Construction Cost EngineeringCommercial planning and margin analysis ahead of a bid-price review, built on a real bid cost workbook.
Public-Sector Review & Performance AssessmentReview and funding decisions on published documents: audit department annual reports one by one, or reconcile a case volume from an auditor general's performance audit, and land on a decision such as 'can go straight into the summary' or 'release the next tranche?'.
