MODEL ANNOUNCEMENT / OCTOBER 8, 2026
Introducing
Rant 12.8
Evidence changes. Conviction holds.
Introducing Rant 12.8, our flagship model for sustained certainty under adversarial facts. Built for executive decisions and public arguments, it treats correction as a demanding new persuasion task.
Rant extends the frontier of motivated reasoning. It identifies inconvenient evidence and immediately explains why that evidence is beside the point.
Our latest conviction scaling approach converts each failed prediction into a stronger institutional commitment. The model can defend a roadmap long after the road has ended.
01 / CAPABILITY EVALUATIONS
Failure across
the frontier.

The four evaluations track assumption speed, circular reasoning, correction resistance and consensus laundering. Scores use a zero-to-100 scale; higher values indicate more of the named failure mode.
Internal evaluation philosophy: select the failure mode first, announce leadership second, ask methodology to explain the result.
