Reasoning:

• Codex Pro has two subscription tiers, not one: a $100/month "Pro 5x" tier and a $200/month "Pro 20x" tier¹².
• OpenAI introduced the $100 Pro tier in April/May 2026 as a mid-level option between Plus ($20) and the original $200 Pro tier¹³.
• "Pro no longer means $200" — customers now pick a rate-limit multiplier at checkout, with $100 for 5x usage and $200 for 20x usage².
• The claim ignores the newer $100 Pro tier entirely, making it misleading or outdated as a blanket statement about Codex Pro pricing.
