• Removed the "Verify you are human" security landing page.
• Added a comprehensive ranking list of over 290 AI models.
• Introduced high-ranking entries for new models including gemini-3-pro, grok-4.1, and gpt-5.1-high.
• Included specific "thinking" and "reasoning" categories for several top-tier models.
