Scoop: SpaceXAI launches new model, Grok 4.5
TL;DR
SpaceXAI is launching Grok 4.5, its first model release since going public and acquiring Cursor. The pitch is aimed at coding, agentic workflows and knowledge work rather than a mainstream consumer chatbot. The company says Grok 4.5 was trained alongside Cursor and beats comparable models on engineering benchmarks. Musk frames it as an Opus-class model that is faster, more token-efficient and cheaper.
Nauti's Take
This is a targeted move against Anthropic and OpenAI inside developers’ daily workflow. The benchmark chart and Musk’s truth-seeking label are predictably PR-heavy; what matters is whether Grok 4.5 produces fewer hallucinations, better patches and stable agent runs in real repositories.
The pricing is aggressive enough to get teams testing. Without EU availability, though, the launch remains theoretical for many European users.
Briefingshow
The important move is not another chatbot launch, but direct placement inside the developer workflow. If Grok 4.5 performs well in Cursor, SpaceXAI competes where models can immediately affect budget decisions: writing code, reviewing changes and automating agentic tasks. The EU exclusion also shows that access remains a strategic constraint.
