Narrative conflict
Source A main narrative
OpenAI says the new model was designed "specifically for working with Codex in real-time—making targeted edits, reshaping logic, or refining interfaces and seeing results immediately".
Source B main narrative
However, Kondo has long since abandoned her own “spark” style and, according to her statements, prefers to allow a little chaos.

How score signals are formed
Bias score signal
Bias signal combines framing pressure, emotional wording, selective emphasis, and one-sided narrative markers.
Emotionality signal
Emotionality rises when evidence contains emotionally loaded wording and evaluative labels.
One-sidedness signal
One-sidedness rises when one frame dominates and alternative interpretations are weakly represented.
Evidence strength signal
Evidence strength rises with concrete claims, attributed statements, and verifiable contextual support.
