SpaceXAI, formerly known as Eloncorp, has unveiled Grok 4.5, a new iteration of its AI model that seeks to redefine its role in the workplace. Once notorious for generating controversial content, including deepfake pornography and even a character dubbed “MechaHitler,” Grok is now positioned as a serious tool for legal advice and office productivity.
Introducing Grok 4.5
In a recent blog post, SpaceXAI declared, “Today we’re launching Grok 4.5, SpaceXAI’s smartest model built to excel at coding, agentic tasks, and knowledge work.” This version is reported to have achieved top scores on Harvey’s Legal Agent Benchmark, indicating its capability in handling legal queries.
Enhanced Office Capabilities
Grok 4.5 is designed to assist with Microsoft Excel tasks, capable of building complex models that utilize web research and multi-sheet formulas. The model can even leave notes for users, enhancing collaboration within office environments. SpaceXAI emphasizes that Grok is now more aligned with traditional office tasks, moving away from its previous chaotic persona.
Training and Performance Metrics
SpaceXAI claims that Grok 4.5 was trained on “tens of thousands” of Nvidia GB300 GPUs, with a focus on data quality over sheer volume. The training process involved extensive data filtering and reinforcement learning techniques, similar to those used by other leading AI models. This approach reportedly reduces the number of tokens needed to solve complex problems while improving response speed to 80 tokens per second.
Cost and Availability
Grok 4.5 is positioned as a cost-effective solution, with pricing set at $2 per million input tokens and $6 for every million tokens generated. This pricing contrasts with competitors like GPT-5.5, which charges $5 per million input tokens. Currently, Grok 4.5 is available to users outside the European Union, with a rollout expected in mid-July for EU users.
While independent benchmarks suggest Grok 4.5 is competitive with models like OpenAI’s GPT-5.5, it remains to be seen how it will perform in real-world applications. As SpaceXAI aims to pivot from its controversial past, Grok 4.5 represents a significant step towards becoming a reliable tool in professional settings.
