Key claims and evidence
Key claims in source A
- OpenAI says that GPT-5-Codex is better than its predecessor at complex, time-consuming programming tasks.
- the bottom 10% used 93.7% fewer tokens than GPT‑5.
- the reason is that it has access not only to a prompt’s contents but also the files open in a developer’s code editor.
- OpenAI debuts GPT-5-Codex model to automate time-consuming coding tasks OpenAI today introduced a new artificial intelligence model, GPT-5-Codex, that it says can complete hours-long programming tasks without user assis…
Key claims in source B
- the model is optimized to feel “near-instant” and can produce more than 1,000 tokens per second when running on ultra-low-latency hardware.
- This preview is just the beginning,” said Sean Lie, Cerebras’ CTO and co-founder.
- The company said these changes reduced per-client/server roundtrip overhead by 80%, per-token overhead by 30%, and time-to-first-token by 50%.
- eWeek previously reported that OpenAI had agreed to purchase compute capacity from Cerebras in a deal valued at more than $10 billion, though OpenAI’s official partnership announcement did not disclose financial details.

Source A · Framing effect
According to OpenAI, the reason is that it has access not only to a prompt’s contents but also the files open in a developer’s code editor.
Possible framing pattern: wording sets a specific interpretation frame rather than neutral description.
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.
