Source Summary

**Grok 4.5** is now callable through Vercel AI Gateway as **xai/grok-4.5**. It accepts text and images for coding, knowledge, and STEM tasks, with low, medium, and high reasoning levels; high is the default.

Practical Implication

Builders should set reasoning explicitly rather than inherit the default for every agent step. Lower levels may suit routine transformations, while deeper tasks can retain high reasoning; gateway routing can introduce the model without changing application code.

The material provides no measurements for quality, speed, cost, or the tradeoff between the three levels. Choosing a setting therefore requires task-level evaluation rather than assuming high reasoning is the best production default.
