SpaceXAI releases Grok 4.5, which Elon describes as an ‘Opus-class model’
SpaceXAI has launched Grok 4.5, an "Opus-class model" according to Elon Musk, designed to handle diverse AI tasks efficiently. This new model boasts superior token efficiency and lower costs compared to leading competitors, aiming to address rising concerns about AI operational expenses.
SpaceXAI has officially released Grok 4.5, its latest large language model, which founder Elon Musk has lauded as an "Opus-class model." This release marks a significant step for the company, offering what it describes as a versatile workhorse capable of various AI applications, including coding, office automation, research, and writing. The model's strength lies in its purported "twice greater token efficiency" and lower operational costs, features that directly address a growing industry concern regarding the expense of AI model usage.
Musk highlighted Grok 4.5's competitiveness by comparing it to Anthropic's Opus model, noting its comparable capabilities but superior speed, token efficiency, and affordability. Internal assessments reportedly position Grok 4.5 on par with Opus 4.7 in terms of performance, while offering a faster and more economical solution. This combination of robust performance and cost-effectiveness is expected to give SpaceXAI a significant edge in the competitive AI market.
Grok 4.5 is priced at $2 per million input tokens and $6 per million output tokens, making it a highly competitive option. For context, Opus 4.7 costs $5 per million input tokens and $25 per million output tokens. Similarly, OpenAI's models have varying price points, with Sol, their most expensive, at $5 for input and $30 for output tokens, and Luna, their most affordable, at $1 for input and $6 for output tokens. These pricing comparisons underscore Grok 4.5's aggressive market positioning.
