SpaceXAI launches Grok 4.5, a model optimized for coding and agentic tasks
SpaceXAI says it has released Grok 4.5, its newest model trained alongside Cursor and optimized for coding, agentic workflows, and knowledge work. The company reports training across tens of thousands of NVIDIA GB300 GPUs, claims roughly 2× token efficiency versus leading models, 80 TPS serving speed, and priced the model at $2 per million input tokens and $6 per million output tokens; Grok 4.5 is available in Grok Build, Cursor, and via the SpaceXAI console with limited free usage offered.
KEY POINTS
- SpaceXAI says it has released Grok 4.5, its newest model trained alongside Cursor and optimized for coding, agentic workflows, and knowledge work.
- The company reports training across tens of thousands of NVIDIA GB300 GPUs, claims roughly 2× token efficiency versus leading models, 80 TPS serving speed, and priced the model at $2 per million input tokens and $6 per million output tokens; Grok 4.5 is available in Grok Build, Cursor, and via the SpaceXAI console with limited free usage offered.
- A model that claims substantial gains in coding/agentic performance, serving speed, and cost efficiency could shift developer tooling, competitive pricing, and benchmark standings among advanced LLM providers.
