What this post added

Introduces Gemini 3 Flash, a new model for the Gemini CLI, optimized for high-frequency workflows and agentic coding. Highlights its performance improvements over previous versions (Gemini 2.5 Pro, Gemini 3 Pro) in terms of speed, cost, and SWE-bench scores for agentic coding. Demonstrates its capabilities in generating complex code (3D Voxel simulation), processing large context windows for code changes, and generating load-testing scripts for stress testing applications.
