OpenRouter's mystery model union-alpha flagged as non-flagship by benchmark-less test
karminski3 · x · 2026-09-17
- karminski3 tested OpenRouter's anonymous model union-alpha and concluded it is likely not a 2026-era flagship, and not from OpenAI/Anthropic or a Chinese lab.
- Key evidence: it builds 3D scenes with three.js r127 (2021), while all flagship models he tested this year have moved to r160 (late 2023).
- He skipped deeper testing given the results.
