⬤ New benchmark data shows xAI's Grok 4.1 Fast sitting at the top of the AI efficiency frontier, combining strong intelligence with remarkably low operating costs. The model breaks the traditional trade-off between performance and affordability, landing squarely in the most attractive quadrant on recent industry charts.
⬤ The data reveals Grok 4.1 Fast achieving an Artificial Analysis Intelligence Index around 64 while keeping running costs among the lowest of any frontier model. This puts it well ahead of GPT-5, GPT-5 Codex, Gemini 3 Pro Preview, and Claude 4.5 Sonnet, all of which sit in much higher-cost territory. The model runs at roughly 90-96 percent lower cost than GPT-5 and Gemini 3 Pro while matching their performance in agentic workflows. Grok 4 Fast also appears in the same high-efficiency zone, reinforcing xAI's strength in cost-effective frontier intelligence.
⬤ The competitive landscape shows wide variation across models. Mid-range options like DeepSeek R1, Kimi K2 Thinking, Claude 4.5 Haiku, and Gemini 2.5 Pro occupy moderate cost and intelligence zones, while Llama 4 Maverick and smaller models fall toward the lower end of the intelligence scale. Grok 4.1 Fast stands distinctly apart, proving that top-tier capability no longer demands premium operating expenses.
⬤ This shift signals a broader industry trend where efficiency is becoming just as important as raw power. As AI workloads scale and infrastructure costs take center stage, models offering high intelligence at low cost are gaining serious traction. Grok 4.1 Fast's position at the efficiency frontier suggests the next wave of AI adoption will focus heavily on performance-per-dollar rather than capability alone, marking a clear change in how the industry evaluates and deploys these systems.
