Overview

Gemini 3.8 Flash is Google's fastest flagship model, built for high-throughput multimodal work. It accepts text, images, video, audio and PDFs, returns text, and carries a 1,048,576-token context window with up to 65,536 output tokens.

On CallMissed, call model gemini-3.8-flash on /v1/chat/completions. Thinking is on by default at medium; pass reasoning_effort of low, medium or high to control it. Note that 3.8 Flash does NOT accept minimal — CallMissed maps that to low for you rather than letting the request fail.

Output pricing is inclusive of thinking tokens, so a reasoning-heavy turn bills at the single output rate with no separate meter.
