Grok 4, developed by xAI, is set to release shortly after July 4, 2025, as announced by Elon Musk. It’s described as a significant leap over Grok 3, with enhanced reasoning, coding capabilities, and multimodal support. Key features include:
- **Advanced Reasoning**: Improved logical consistency and problem-solving, with benchmarks showing 95% on AIME (math), 88% on GPQA (science), and 75% on SWE-bench (coding).[](

Concerns exist about potential biases due to Musk’s influence and past issues with Grok’s responses, like the white genocide controversy. Critics also note challenges with voice mode stability and app performance. Despite this, early feedback praises its speed and reasoning, positioning it as a competitor to GPT-4.5, Claude 4, and Gemini 1.5.[](
