VERITAS vs Wikipedia API — when to use each for LLM grounding

Wikipedia is a free, vast knowledge encyclopedia. VERITAS is a typed, signed claim-verification API. They aren't competitors — they solve different shapes of the same problem.

Honest verdict per use case

Use Wikipedia when:

  • You need broad knowledge coverage — geography, history, biography, general science
  • Free-text content (summaries, narrative) fits your application
  • You can benchmark and accept the provider latency in your own stack
  • You do not need SourceScore's structured integrity metadata
  • Your application is non-commercial OR comfortable parsing prose

Use VERITAS when:

  • You need atomic verified claims for AI/ML facts (model releases, paper dates, parameter counts)
  • You're building a generate-then-verify pipeline
  • You need structured claim records and cited evidence
  • You need structured JSON outputs (not prose to parse)

Use both when:

Most production grounding pipelines do both. Wikipedia handles general-knowledge queries ("capital of France", "founder of Apple"); VERITAS handles AI/ML specifics where cited evidence + atomic-claim shape matter. Cascade: try VERITAS first for AI/ML topics, fall through to Wikipedia for broader queries.

Concrete: the "Transformer paper" query

Both Wikipedia and VERITAS can answer "Who wrote the Transformer paper?"

  • Wikipedia: Article on "Attention is all you need" — narrative paragraphs naming Vaswani et al. Your application parses the article. Response time depends on the request and provider. No signature.
  • VERITAS: POST /api/v1/verify{claim: "Transformer paper authors"} returns:{bestMatch: {subject: "Transformer architecture", predicate: "introduced_in_paper", object: "Attention Is All You Need (Vaswani et al., 2017)"}, signature: {...HMAC-SHA256...}}. The HMAC field is SourceScore-issued integrity metadata, not a public signature.

For a chatbot, Wikipedia's prose may be richer. For a production agent loop that needs to cite the fact in an audit trail, VERITAS's typed record with cited evidence is cleaner.

What we're not

VERITAS doesn't replace Wikipedia. Wikipedia covers everything; we cover AI/ML. Our methodology (cited primary evidence, source counts, and editorial review) doesn't scale to all human knowledge. Wikipedia's open community model does. The right move for most production systems is to use both.
