Emphasizes availability while minimizing or omitting all validation, limitations, and operational realities; treats platform listing as functional endorsement.

How the spin works
Combines naming authority ('Step 5 Preview'), technical-sounding specs ('1M-context MoE'), and platform affiliation ('OpenRouter') to create an impression of substance and momentum — but the claim rests entirely on a title with no descriptive or evidentiary payload, creating a gap between perceived significance and actual information.
