Gemini 3.6 Flash (gemini-3.6-flash) and Gemini 3.5 Flash-Lite (gemini-3.5-flash-lite) are generally available (GA) and ready for production use.
Gemini 3.6 Flash: Stronger performance on complex agentic and multimodal tasks while reducing token usage, at a lower price point than 3.5 Flash.
Gemini 3.5 Flash-Lite: The fastest, lowest-cost model in the 3.5 family. Outperforms prior Flash-Lite generations for high-throughput execution.
This guide explains what's new in each model, what API changes affect your code, and how to migrate.
Tip: You can automate this migration with a coding agent that supports skills (like Antigravity). Run /gemini-interactions-api migrate my app to Gemini 3.6 Flash
