The article compares multiple AI search tools and concludes that Grok 4.20 currently leads due to a four-agent system that searches in parallel, cross-checks results, and delivers structured outputs with many sources. It explains each agent's role, why Grok reduces hallucinations and improves instruction-following, and how to access and customize search agents on grok.com with paid tiers.
Key Takeaways
