Google released Gemini 3.8 Flash for fast general inference and a security-hardened Flash Cyber variant aimed at agent and high-volume dev workloads.

Summary written from the original first-party source — the link to it is at the end of this post.

Google shipped Gemini 3.8 Flash on September 2, its fast general-inference model, alongside a second variant: Gemini 3.8 Flash Cyber. The Cyber tier is security-hardened and aimed at agent workloads — the ones where a model is executing code, touching external systems, and handling sensitive pipelines rather than just answering chat prompts.

What changed

Both slot below the Omni tier in Google’s lineup and bring the Flash cost profile up to date for high-volume developers: low latency for everyday reasoning at the standard-end pricing Flash is known for. The “Flash” naming is Google’s guarantee of a certain latency-and-cost envelope, so the move is aimed squarely at production developers choosing a workhorse model for a high-traffic product rather than someone hunting for maximum benchmark scores.
