On Wednesday, SpaceXAI launched Grok 4.5, its newest AI model designed to help users write code, complete complex work tasks, and handle research-heavy projects. SpaceXAI (formerly xAI) operates as a wholly owned artificial intelligence unit of Space Exploration Technologies Corp. (NASDAQ:SPCX). The company said Grok 4.5 is its strongest model so far and was trained alongside Cursor. SpaceXAI priced Grok 4.5 at $2 per million input tokens and $6 per million output tokens, making it cheaper than some rival AI models. According to Counterpoint analyst Neil Shah, Grok 4.5 could pressure enterprise AI pricing by offering a lower-cost option for high-volume coding and agentic AI workloads. Shah said on Thursday that enterprises are facing “token bill shock” and that Grok 4.5 is priced below Anthropic’s Claude Opus 4.8 pricing of $5 for input and $25 for output. Shah noted enterprises are moving toward diversified AI stacks, routing workloads based on cost, speed, and accuracy. He added that if Grok maintains its cost advantage while narrowing the accuracy gap, it could reshape enterprise AI economics and pose a new pricing threat to OpenAI and Anthropic. SpaceX shares were up 0.88% at $149.60 during premarket trading on Thursday.
