●SUNSET — Three days until the image models shut down: Imagen 4 and the Gemini 3 Image family stop on August 17●MIGRATE — gemini-3.1-flash-image is the recommended target; calls to generate_images() fail hard after the cutoff, so there is no grace period●FLASH — Gemini 3.6 Flash is generally available, with better token efficiency and stronger code and agentic planning at a lower price than 3.5 Flash●LITE — Gemini 3.5 Flash-Lite also reached GA as a low-latency, cost-conscious subagent option aimed at high-volume automation●PARAMS — The sampling parameters temperature, top_p, and top_k are now deprecated, so existing calls are worth revisiting●ROBOTICS — gemini-robotics-er-1.6-preview shuts down on August 31, so this is the window to plan the migration●SUNSET — Three days until the image models shut down: Imagen 4 and the Gemini 3 Image family stop on August 17●MIGRATE — gemini-3.1-flash-image is the recommended target; calls to generate_images() fail hard after the cutoff, so there is no grace period●FLASH — Gemini 3.6 Flash is generally available, with better token efficiency and stronger code and agentic planning at a lower price than 3.5 Flash●LITE — Gemini 3.5 Flash-Lite also reached GA as a low-latency, cost-conscious subagent option aimed at high-volume automation●PARAMS — The sampling parameters temperature, top_p, and top_k are now deprecated, so existing calls are worth revisiting●ROBOTICS — gemini-robotics-er-1.6-preview shuts down on August 31, so this is the window to plan the migration
