SpaceXAI Grok 4.5: New AI Coding Model Launched

SpaceXAI has launched Grok 4.5, a new AI model designed for coding and agentic tasks. This model is priced at $2 per million input tokens and $6 per million output tokens. Access is available through Grok Build, all Cursor plans, and the SpaceXAI developer console. Elon Musk described Grok 4.5 as an "Opus-class model, but faster, more token-efficient and lower cost." It runs at 80 tokens per second and offers roughly twice the token efficiency of comparable models. Grok 4.5 also supports finance and legal work, including building Excel models and creating PowerPoint presentations. However, it does not outperform the largest, most recent models from OpenAI and Anthropic. The model was trained in partnership with Cursor. European Union users are expected to gain access by mid-July. This launch comes amidst increased regulatory scrutiny of powerful AI models. This matters because it introduces a new, potentially more efficient option for developers and businesses utilizing AI.
