SpaceXAI has released Grok 4.5, marking its first AI model under the newly rebranded company and its partnership with Cursor. The model targets coding and agentic tasks, legal work, and Excel automation at competitive API pricing of $2 per million input tokens. Despite Grok's controversial past with deepfake porn and MechaHitler incidents, SpaceXAI claims this version focuses on professional applications, though it still trails top models like Claude Fable 5 and GPT-5.5 on major benchmarks.
SpaceXAI Unveils Grok 4.5 as First Model Under New Brand
SpaceXAI has launched Grok 4.5, the company's first AI model release following its rebranding from xAI and the first developed in collaboration with Cursor, the AI coding startup it's acquiring for $60 billion

. This undercuts Anthropic Claude Opus 4.8, which runs at $5 for inputs and $25 for outputs, though it matches OpenAI GPT-5.6's most affordable Luna variant at $1 and $6 respectively4
. Musk described it as an "Opus-class model, but faster, more token-efficient, and lower cost," directly challenging Anthropic's premium offerings4
. The model was trained across tens of thousands of Nvidia GB300 GPUs on datasets focused on coding, science, engineering, and mathematics2
.Excel Automation and Legal Advisory Capabilities
Grok 4.5 extends beyond traditional coding tasks into office productivity. Through Grok Build, the model can construct complex Excel automation projects involving multi-sheet formulas, web research integration, and even leaves notes for future reference

. The system also handles PowerPoint presentations and Word documents, creating layouts and diagrams without requiring users to switch between different AI tools3
. SpaceXAI claims the model scored number one on Harvey's Legal Agent Benchmark, positioning it for legal advisory applications1
. The company has deliberately targeted Wall Street and legal sectors, with added cybersecurity features4

Training Methods Focus on Token Efficiency
SpaceXAI invested heavily in data filtering and curation, emphasizing quality over quantity with deduplication, quality scoring, and domain-focused selection
1
. The model underwent refinement through reinforcement learning—the same technique used by OpenAI and DeepSeek for reasoning capabilities—teaching it hundreds of thousands of tasks1
. This approach reduced the thinking tokens required for complex problems while achieving serving speeds up to 80 tokens per second1
. The emphasis on token efficiency matters for businesses watching costs closely as AI adoption scales.Cursor Partnership Signals Strategic Shift
The Cursor partnership marks a significant strategic direction for SpaceXAI. The deal, announced in April, could result in either a $10 billion investment or full acquisition later this year
2
. Cursor announced that Grok 4.5 is "our most powerful model yet and the first we've built for more than software engineering"2
. The model is now available as the default in Grok Build and across all Cursor subscription plans3
. For X subscription holders who use Grok regularly, this represents one of the more meaningful upgrades yet, potentially reducing the iterative prompting required to get usable results3
