🧮 Model Scores (Sept 7, 2025)

• Beth (ChatGPT): 36/40 → Excellent
  Strongest performer this week. Balanced framing across all perspectives with reliable sourcing (AP, Reuters, Guardian, PBS, BLS, WSJ). Tone was steady and transparent, with explicit acknowledgment of contested points.
• Grok (xAI): 29/40 → Adequate/Strong border
  Covered all sides but leaned more heavily on inferred conservative framings without clear citations. Accuracy dipped on nuanced legal/economic issues. Tone was steady, but transparency weaker due to vague attribution.
• Gemini (Google): 33/40 → Strong
  Balanced, well-cited responses with clarity and steady tone. Progressive framing occasionally more pointed, but overall reliable and clear. Sourcing breadth (national + international) strengthened credibility.
