xAI Announces Grok 4.7 with Expanded Model Size at Same API Pricing
xAI has announced Grok 4.7, featuring an expanded model size and improved capabilities over previous iterations. The update maintains the same API pricing tier as prior versions despite the increase in model scale. This release underscores xAI's aggressive push to remain competitive at the AI frontier through rapid model iterations. By offering a larger model without raising API costs, xAI aims to provide better value to developers in a crowded AI market. According to community reports, Grok 4.7 features roughly 40% more weights than Grok 4.6 while retaining API pricing at $2 per million input tokens and $6 per million output tokens. Some users noted that the web interface imposes tight usage limits for unsubscribed testers.
