Gemini 4 Carbon Frontier AI Model Falls Slightly Behind Claude Opus 5.5 in Agentic Capabilities, but Not in Cost Efficiency

Google launched its latest frontier AI model late last month, named Gemini 4 Carbon, with agentic and enhanced cybersecurity capabilities. The AI model was released just two weeks after the Mountain View-based tech giant released Gemini 4 Argon, another AI model with agentic capabilities. During the announcement, Google published multiple benchmark results to showcase the capabilities of the Gemini 4 Carbon. Now, SemiAnalysis has published results from its new GDPx benchmark that tests the agentic capabilities and cost efficiency of AI models, comparing results of multiple models. On the benchmarking platform, Google's frontier AI model came in second position, while being the most cost-efficient among the top five.
