### History The story of the Chrysler Building began in 1928, when automotive titan Walter P. Chrysler, founder of Chrysler Corporation, bought the property from Coney Island developer William H. Reynolds for $2 million. Chrysler hired architect William Van Alen, who had previously designed a skyscraper for Reynolds on the site, to create the world’s tallest tower. Construction on Chrysler’s project began in 1929 and was completed in 1930. Reaching a height of 1,048 feet, including its 125-foot

📜 Methodology Disclosure

Verification Pipeline — The Distiller v2

This report was generated by The Distiller's automated verification pipeline. The methodology consists of three stages:

Stage 1: Claim Extraction (Triage)

The source text is processed by a large language model (GPT-4o-mini) that atomizes it into individual, verifiable claims. Each claim is classified as either a HARD_FACT (contains specific verifiable details) or SOFT_CLAIM (subjective/opinion). Only HARD_FACTs proceed to verification.

Stage 2: Evidence Retrieval

Each HARD_FACT claim is searched against live web sources using the Brave Search LLM Context API. Evidence snippets are retrieved from up to 5 sources per claim, with each source scored by trust tier:

  • .gov domains — Trust weight: 1.0 (government sources)
  • .edu domains — Trust weight: 0.95 (academic institutions)
  • .org domains — Trust weight: 0.70 (nonprofits, Wikipedia)
  • .com domains — Trust weight: 0.50 (general web)
  • Other domains — Trust weight: 0.40

Stage 3: Audit

A second, more powerful language model (GPT-4o) performs the verification audit. For each claim, it evaluates the retrieved evidence and issues a verdict:

  • TRUE — Evidence explicitly confirms the claim with matching specifics
  • FALSE — Evidence explicitly contradicts the claim (different date, number, name)
  • UNVERIFIABLE — Insufficient or irrelevant evidence to confirm or deny

Automated Safety Rules

  • Negative Evidence Rule: If no relevant evidence is found, the verdict is automatically set to UNVERIFIABLE (never TRUE by default)
  • Numerical Hard-Match: Numbers in claims are programmatically compared to numbers in evidence. Mismatches are automatically flagged.
  • Verdict Hierarchy: The overall document verdict follows a strict hierarchy — any FALSE claim makes the overall verdict FAILED, regardless of other claims.

Limitations

  • Evidence is limited to publicly available web sources indexed by Brave Search
  • Claims requiring specialized databases (e.g., medical records, proprietary data) may return UNVERIFIABLE
  • The pipeline relies on web search freshness — very recent events may lack evidence
  • Source trust scoring uses TLD-based heuristics; individual page quality is not assessed
  • The audit LLM may exhibit biases inherent to its training data

Compliance Statement

This report is provided for informational purposes as part of an AI-generated content verification workflow. It is designed to support — not replace — human review processes. Organizations subject to the EU AI Act or similar regulations should use this report as one input in their broader compliance framework.
