modelprint
Who is really behind that API? Fingerprint any OpenAI-compatible endpoint in the browser: 9 infrastructure probes, side-by-side comparison, community-extensible.
The lack of measurement causes existence of such claims or discussion. Last Friday I built this Model fingerprint calculator and I tested between OxAlpha with all other claimed models, the only match was GLM. It generates, or measures regardless of the model-weights or its training data. No need guessing when one can measure it. I tested with Gemini family too, far different. Here is the link to my experiment https://github.com/unclecode/modelprint
