Quick answer: compatibility and sources

It depends on your task, available memory, file format and license. The records below match this guide’s filters. Check the linked file evidence before choosing: a catalog match does not prove runtime support, safety or answer quality.

An answer pack is a question-specific filter over catalog records. It is not a benchmark, safety review or guarantee that a model will run.

As of .

The machine-readable answer record and its citation list link to the source data behind this guide. Catalog matches are not a benchmark or model test.

Page sources

Page-copy source revision 8871bab84e1cf80aea1686a944ec335078a6c036 · Source files: apps/web/server.mjs, apps/web/lib/answers-copy.mjs, apps/web/lib/answers-landing-html.mjs, apps/web/lib/answer-pack-html.mjs, apps/web/src/App.tsx, apps/web/lib/aeo-page.mjs · Full revision record

Key facts

Answer pack
Filters catalog rows for one reader question; order is not a quality ranking.
Citation API
Machine-readable citations link each row to source endpoints.
Hosting line
Describes delivery status separately from license permission.
Unmeasured runs
No row implies a successful model test unless run evidence says so.

Evidence you can inspect (plain text)

  • GET /api/answers indexes public answer packs.
  • GET /api/answers/rag-embeddings exposes machine-readable rows when the slug exists.
  • Open /artifact/hf-model-qwen-qwen3-8b/files for exact filenames, availability and any recorded SHA-256 for the model.
  • Open /evidence/artifacts/hf-model-qwen-qwen3-8b for run-readiness evidence tied to that record; absent receipts stay unmeasured.
  • Open /api/artifacts/hf-model-qwen-qwen3-8b/card.md for machine-readable source facts (not a runtime test).
  • Guides do not assert model tests unless linked run evidence includes a receipt.

Unmeasured states are stated explicitly; this page does not invent run scores or compatibility guarantees.

Which date applies to which fact

  • Answer API rows assembled:
  • Committed page-copy sources:
  • Upstream model metadata: Dates on artifact records when shown; not implied by page-copy revision
  • Run receipts: Only on /evidence pages when recorded; otherwise unmeasured

Page-copy revision (Updated line above) identifies committed text sources, not upstream model edits or test outcomes.
