Musk's Grok 4.5 Challenges OpenAI, Anthropic in AI Race

Elon Musk's xAI has launched Grok 4.5, intensifying the AI arms race with a direct challenge to OpenAI and Anthropic.

The model, launched publicly in early July, is designed to undercut competitors on price while delivering comparable or superior performance. xAI claims it uses 4.2x fewer output tokens than Anthropic's Claude Opus 4.8 on certain coding benchmarks.

Grok 4.5 is priced at $2 per million input tokens and $6 per million output tokens, with a 500k-token context window. It's integrated into developer tools like Cursor, aiming to capture market share among professional software engineers.

The infrastructure powering Grok 4.5 consists of tens of thousands of NVIDIA GB300 GPUs. This massive compute requirement highlights the growing strain on GPU supply for frontier AI models.

For crypto-adjacent compute markets, the implications are mixed. The model's efficiency could reduce per-task compute demand, potentially pressuring decentralized GPU rental networks. However, its success in driving wider AI adoption could boost overall volume for those same networks.
