SpaceXAI has officially launched its latest AI model, Grok 4.5, which is specifically designed for coding and agentic tasks, marking it as the company's most sophisticated offering to date. The model was developed using tens of thousands of Nvidia GB300 GPUs, featuring advanced data filtering, deduplication, and quality scoring. Grok 4.5 is available via SpaceXAI's Grok Build coding agent and can be accessed through an API in the developer portal, with plans for EU availability by mid-July. Pricing is set at $2 per million input tokens and $6 per million output tokens, providing a cost-effective option compared to competitors like Anthropic and OpenAI. The significance of Grok 4.5 lies in its potential to enhance enterprise AI tools, coinciding with SpaceX's acquisition of the AI coding startup Cursor for $60 billion. This entry into the market comes at a time of heightened competition, especially with rival models such as OpenAI's GPT-5.6 launching shortly after. SpaceXAI’s CEO, Elon Musk, emphasized that Grok 4.5 offers improved speed and efficiency while maintaining lower costs, positioning it as a key player in the rapidly evolving AI landscape. This launch reflects a broader trend in the AI/ML community towards developing more powerful, efficient, and accessible tools for diverse applications.
