Editorial interest 82/100 Selection signal · not a rating of the site

A diagnostic tool that probes OpenAI- and Anthropic-compatible endpoints for signs they are serving a different model than advertised.

Landing page captured for the 2026-09-06 issue.

Field notes

Relaylens accepts an endpoint base URL, API key, model identifier, protocol selection, and probe depth, then runs a sequence of compatibility and behavioral tests. Its displayed menu ranges from five quick probes to thirteen full probes, with an extreme mode adding a maximum-window ladder. The page says keys remain in memory only for the job and are never logged or written to disk; estimated token spend is shown before the run.
