SpaceXAI has released Grok 4.5, a new AI model described by founder Elon Musk as comparable to a competitor's Opus model. The company claims the model is twice as token-efficient as other leading models, meaning it can perform typical AI tasks like coding, writing, and research at lower cost. Grok 4.5 is priced at $2 per million input tokens and $6 per million output tokens, which is substantially cheaper than comparable models from competitors. This release comes as SpaceXAI competes in an active market where multiple companies are releasing new AI models with claims of improved efficiency and capability.
