xAI by Elon Musk Launches Grok 4 With Faster Processing and Cost-Effective Design

Elon Musk’s company xAI has introduced its latest breakthrough — Grok 4 Fast, a model designed to deliver efficiency and innovation together. Unlike its predecessor, this Affordable AI Model 2025 merges reasoning and non-reasoning abilities into one streamlined system, making it easier for businesses and individuals to use without juggling multiple frameworks.

According to official updates from Elon Musk AI News, Grok 4 Fast requires nearly 40% fewer thinking tokens compared to Grok 4, yet it delivers close benchmark results. Reports suggest it can operate at a fraction of the cost — up to 98% cheaper — without sacrificing performance.

Benchmark testing showcased impressive outcomes: 93.3% on GPQA Diamond, 92% on HMMT 2025, 85.7% on AIME 2025, along with 95% on SimpleQA and 74% on X Bench Deepsearch. These results highlight Grok 4’s adaptability across diverse tasks, from code execution to advanced search applications.

From a design perspective, Grok 4 Fast introduces a 2-million-token context window to handle larger inputs seamlessly. The integration of reinforcement learning improves speed, lowers latency, and makes the model more user-friendly. It transforms AI into a smoother, more scalable solution that reflects innovation at its core.

Currently, Grok 4 Fast is available through xAI Grok 4 Launch platforms including grok.com, iOS, Android, OpenRouter, Vercel AI Gateway, and the xAI API. Pricing begins at just $0.20 per million input tokens, making it an accessible choice for developers and enterprises seeking scalable yet affordable AI solutions..
