The 5 tools XF Model Source offers

Tool	What it does
`benchmark`	Run a live A/B test against the engine's TOP 3 PICKS for a stated purpose — the engine chooses the candidates from the full catalog. Generates 5 representative test queries (auto-expands to 10 or 15 if results are too close to call), runs t Inputs: purpose
`compare`	Run a live A/B test between 2–5 user-specified models for a stated purpose. NO ranking step — the supplied model_ids ARE the candidate set. Generates 5 representative test queries from the purpose, runs them through every named model in par Inputs: purpose, model_ids, primary
`discover`	Show which quality dimensions matter for a stated purpose, WITHOUT ranking any models. Returns the inferred weights and the discovery-walk trace. Useful for understanding how XFMS interprets the purpose before committing to a pick. Inputs: purpose
`pick`	Return the single best LLM for a stated purpose. Concise output, no list. Use when the user has settled on the criteria and just wants one answer. Inputs: purpose
`rank`	Rank LLMs for a stated purpose. Returns a shortlist with weights, scores, and plain-English rationale per pick. Use when the user wants to see and compare alternatives, not just one answer. Inputs: purpose, top_n, capabilities, primary

Where this comes from

Publisher: dev.xpansion. Endpoint host: xfms.xpansion.dev. ARD identifier: urn:air:dev.xpansion:mcp:xfms. First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page is inferred from its name. Ranking in Neuronto search is never for sale.
