SpaceXAI launches Grok 4.5, claims major gains in coding, engineering and enterprise tasks
Follow UsGrok 4.5 is designed for coding, engineering, and office work, with support for Excel, PowerPoint, and Word automation.
The company claims the model delivers stronger reasoning while using fewer tokens, making it faster and more cost-efficient.
Grok 4.5 is available now on Grok Build, Cursor, and the SpaceXAI API, with EU rollout expected later this month.
Elon Musk’s SpaceXAI has introduced Grok 4.5, the latest version of its AI model. It comes with improvements in coding, software engineering and enterprise productivity. The company says the new model is its most capable AI system yet and has been designed to tackle complex, multi-step tasks with faster reasoning while using fewer computing resources.
SurveyAs per SpaceXAI, Grok 4.5 has been trained on large scale datasets covering programming, mathematics, science and engineering. The company says it has improved the training pipeline by improving data quality, filtering duplicate information and using reinforcement learning techniques focused on real-world software development.
The company claims Grok 4.5 performs strongly across several industry benchmarks used to evaluate coding and engineering capabilities. On the SWE Marathon benchmark, which measures performance on long-running software engineering tasks, Grok 4.5 reportedly outperformed competing AI models. It also posted competitive results on benchmarks including DeepSWE, Terminal Bench, and SWE Bench Pro, though some rival models continued to lead in certain categories.
In a blog post, SpaceXAI also stated that the model requires considerably fewer output tokens to complete programming tasks than some competing AI models, allowing it to generate responses faster while reducing inference costs. The company also claims the model delivers responses at speeds of up to 80 tokens per second.
Along with the software development, Grok 4.5 is also positioned as a productivity tool for enterprise users. It can generate Excel spreadsheets with formulas, create PowerPoint presentations using native design elements, draft Word documents and assist with research-intensive office work. The model is now the default AI engine inside Grok Build, where it can build applications from a single prompt and assist with complex document creation.
SpaceXAI has priced Grok 4.5 at $2 per million input tokens and $6 per million output tokens. It is available starting today through Grok Build, Cursor, and the SpaceXAI API. However, the rollout excludes the European Union for now, with availability there expected later this month.
