SpaceXAI undercuts AI rivals on price with Grok 4.5
SpaceXAI has released its Grok 4.5 model at a fraction of rival prices, intensifying a cost war that could accelerate AI adoption among European businesses.
SpaceXAI released Grok 4.5 on Wednesday, its first major product launch since the company went public several weeks ago. The model is designed to handle the routine knowledge work that businesses have been eager to automate, including coding, app-building, office administration, research and writing.
For European enterprises, the release matters primarily because of its aggressive cost structure. SpaceXAI is pricing the model at $2 per million input tokens and $6 per million output tokens. That represents a steep discount compared to Anthropic’s Opus 4.7, which charges $5 for input and $25 for output.
SpaceXAI founder Elon Musk announced the rollout on X, the social platform owned by SpaceXAI. “Based on strong positive feedback from customers in our beta test program, @SpaceXAI will make Grok 4.5 available to the public tomorrow. It is an Opus-class model, but faster, more token-efficient and lower cost,” Musk wrote.
The company claims the new model offers "twice greater token efficiency" than leading competitors. If accurate in real-world applications, this directly addresses a major barrier for European companies: the high running costs of integrating AI into daily operations. However, the pricing landscape remains complex. OpenAI already offers a cheaper bottom-tier model, Luna, at $1 per million input tokens and $6 per million output tokens.
Musk later sought to frame the model against its direct rival. “Our internal assessment is that Grok 4.5 is roughly comparable to Opus 4.7, but much faster. The combination of capability, faster speed and lower cost is what makes it competitive,” he added.
SpaceXAI’s pricing push arrives as the competitive landscape shifts rapidly this week. OpenAI is scheduled to release GPT 5.6 on Thursday, a model the company describes as its "strongest model yet." That release had previously been delayed by the Trump administration due to security implications.
Benchmark data released by SpaceXAI places Grok 4.5 just short of best-in-class performance. For corporate buyers and investors tracking the sector, the emerging calculus is whether SpaceXAI’s performance gap is worth the operational savings. How European businesses answer that question will dictate the pace of AI adoption across the continent's economy.
