Gemini 2.5 Flash vs Grok Build 0.1

Google's balanced Gemini 2.5 model, tuned for price and performance rather than the top of the range. It was the first Flash model to reason visibly, showing its thinking as it works, and you can turn that thinking on or off per task. Reads text, images, video, and audio across a million-token context. A dependable workhorse, now a generation behind Google's newest Flash releases.

xAI's coding model, purpose-built for autonomous software engineering rather than chat. Grok Build 0.1 acts as an engineering agent: it reasons through a problem, writes code, runs your terminal, checks for errors, and fixes its own mistakes in a loop. It reads text and images, always reasons before answering, and natively supports Model Context Protocol. Built for long-horizon coding that runs with little supervision, at a low cost, tuned for agent loops.
