SpaceXAI (SPCX.US) has introduced a new artificial intelligence model developed in partnership with AI programming startup Cursor, designed to handle financial, legal, and coding tasks with greater proficiency. This move is part of Elon Musk's company's strategy to gain an edge in competition against rivals like Anthropic PBC and OpenAI.
The software, named Grok 4.5, represents the first jointly developed AI model from the two companies. This launch comes just weeks after SpaceX formally agreed to acquire Cursor in a deal valuing the startup at $60 billion.
According to a blog post published Wednesday, the new model is intended to "tackle difficult and long-running tasks," including software engineering, a core focus area for many leading AI developers. However, unlike Cursor's previous models, Grok 4.5 is built to handle a broader portfolio of work, such as legal and financial services. The blog post also stated that Grok 4.5 features enhanced cybersecurity capabilities.
The collaboration with Cursor is part of a broader effort by Musk's company to catch up in the AI race and attract more enterprise customers. Earlier this year, Musk stated that his AI startup, known as xAI before merging with SpaceX, had fallen behind in programming, which triggered a wave of personnel changes to rebuild the venture. The AI team, now known as SpaceXAI, released its first coding agent in May to compete with products from Anthropic.
Ahead of a highly anticipated IPO, SpaceX announced an agreement granting it the right to acquire Cursor—one of the fastest-growing startups ever and a central player in the so-called "vibe coding" era. The two companies subsequently began collaborating on a new model by sharing data and computing resources.
Musk's company has also been attempting to focus on financial tasks to win over clients on Wall Street, part of its effort to further boost revenue. The release of Grok 4.5 comes at a time of increased government scrutiny of new models, particularly regarding cybersecurity capabilities.
In the blog post, Cursor stated it has taken measures to "detect and block bad actors." The company said its goal is to "preserve legitimate security work, including finding and fixing vulnerabilities, while restricting workflows most likely to cause harm."
