In tandem with the performance breakthroughs, the new models—Grok 4 Fast—are also massively cost-effective. It boasts a 2 million token context window, doubling the previous leaders like Google’s Gemini models. Even more impressive is its 47 times cheaper operational cost compared to Grok 4, achieved through smart reinforcement learning strategies that optimize when and how the model processes information.
This cost reduction is transformative, making high-performance AI accessible not just to tech giants but to developers and entrepreneurs worldwide. As Josh notes, this could enable AI on smartphones and in remote areas, democratizing intelligence at an unprecedented scale.
