Model spin tracker
Every article is scored blind — outlet names, bylines and tell-tale boilerplate are stripped before the models see the text — by each active scorer, using the same versioned prompt and calibration anchors. The published number is the ensemble median; the tables below show how far each model sits from it, so you can see the models' own lean as well as the outlets'.
Where each model sits
Average left/right position each model gives articles, across 844+ blind scorings. The scale is zoomed to ±1 on our −10 to +10 lens.
OpenAI GPT-5.6 Sol -0.14
Anthropic Claude Sonnet 4.5 -0.11
Google Gemini 3.7 Flash -0.08

Favorability drift
How much warmer (+) or harsher (−) a model rates the story's subject than the group's median, on the −10 hostile to +10 laudatory scale. It measures tone toward the people or policy covered.
Lens drift
How far left (−) or right (+) a model places an article's framing compared with the group's median, on the −10 to +10 political lens. It measures where the model thinks the slant sits.
