In this video, we put the newly released Gemini Flash-Lite Preview (09-2025) from Google head-to-head against Grok 4 Fast from xAI. After a quick comparison of model positioning and pricing, we run both through a series of hands-on tests: browser-based OS simulation, HTML generation, roleplay capabilities, 3D FPS game generation, and freestyle Python coding.

This test dives into speed, refusal behavior, creativity, and agentic control to see how these lightweight but powerful models handle real-world, multi-step tasks. Which one performs better in raw interaction and practical use? Let’s find out.
