SpaceXAI launched Grok 4.5 on July 8 as its first real entry into the enterprise market following its acquisition of AI coding platform Cursor and rebranding from xAI on July 6. The model release is the first since SpaceX went public in June and will help SpaceXAI compete with other frontier model providers, particularly in coding. Grok 4.5 is built for coding, agentic tasks and knowledge work and was trained alongside Cursor on the Nvidia GB300 platform. SpaceXAI said it invested heavily in data filtering and curation and scaled reinforcement learning with a focus on per-token intelligence. The new model is SpaceXAI's first model specifically designed for agentic coding. Previously, the vendor ventured into coding with its Build CLI, a coding agent for developers. However, the Grok model has long been aimed mostly at consumers using Musk's X social media platform, with little enterprise adoption. Grok 4.5 shows how SpaceXAI is targeting the enterprise market, aiming to rival AI coding models such as Claude Code from Anthropic and Codex from OpenAI. The model release comes on the cusp of SpaceX's $75 billion IPO and its June 16 acquisition of the popular agentic coding platform Cursor for $60 billion in stock. SpaceXAI trained Grok 4.5 on trillions of tokens of Cursor data, which enables the model to run with both existing software and in developer-agent interactions. Cursor and SpaceXAI revealed that, although Grok 4.5 is optimized for coding, its training data is somewhat broader than that of Cursor's coding model, Composer 2.5. Grok 4.5 and Cursor models are meant to be complementary. In addition, SpaceXAI is showing that Grok is more than a model that X users can interact with on the platform. The vendor's focus on coding is also good for the market because it leads to more competition, which benefits enterprises the most. One way SpaceX is trying to make Grok 4.5 different from other models is with pricing. SpaceX priced the model at $2 per million input tokens and $6 per million output tokens, claiming it achieves twice the token efficiency of other models. Comparatively, Claude Opus 4.8 is $5 per million input tokens and $25 per million output tokens. OpenAI's GPT-5.6 Sol, in preview, costs $5 per million input tokens and $30 per million output tokens. Grok 4.5 is available in Grok Build, in Cursor and from the SpaceXAI console.
