Artificial Analysis says Gemini 4 Argon (high) matches GPT-6 Astra (max) on its Intelligence Index and has a 15% hallucination rate, compared with 51% for Astra (Artificial Analysis)

Artificial Analysis reports that Google’s Gemini 4 Argon (high) matches GPT-6 Astra (max) on its Intelligence Index while delivering materially better reliability, with a 15% hallucination rate versus 51% for Astra, and at about 60% of the cost per task. For CIOs and technology leaders, this suggests a potentially stronger ROI for enterprise AI deployments: lower inference spend, less output-risk, and more room to scale use cases where accuracy and economics are both critical. IT organizations should view this as a signal to re-benchmark model performance, cost, and guardrails before standardizing on a single vendor or model tier.
