Grokipaedia.com cuts through the AI hype with impartial scorecards for top 

agents: Grok 4, ChatGPT-5, and Gemini 2.5 Pro. We benchmark on real-time access, reasoning, hallucinations, and efficiency using standards like GPQA, MMLU, and SWE-bench. Grok leads in live X/web pulls, ChatGPT in filtered creativity, Gemini in massive context—pick your fighter based on facts, not fluff.

Quick Contender Rundown
  • Grok 4 (xAI): MoE-powered for STEM speed; excels in unfiltered trends but risks hallucinations.
  • ChatGPT-5 (OpenAI): MMLU-polished for strategy; low-risk but conservative on urgency.
  • Gemini 2.5 Pro (Google): 1M+ token beast for depth; strong ecosystem but volume-heavy.
