SpaceX's Grok 4.5 launches at half the price of rivals — here's why that could rattle Anthropic and OpenAI

SpaceX introduced Grok 4.5, a coding and autonomous-agent model developed with Cursor after its reported $60B acquisition. The company is positioning the model around cost efficiency and speed, pricing it well below rival frontier models while claiming comparable real-world usefulness despite not leading benchmarks.

The launch signals a shift in AI competition from benchmark dominance toward usable performance per dollar, especially for developers building agents and software tools. If Grok 4.5 delivers reliably at scale, it could intensify pricing pressure on frontier AI providers and accelerate demand for vertically integrated AI stacks.
