Google: Gemini 3.8 Flash (batch)

Google: Gemini 3.8 Flash (batch) is a Google model that accepts text, image, video, audio, and file inputs, so a single endpoint can handle mixed-media workloads. It offers a context window of 1,048,576 tokens and can return up to 65,536 tokens per completion, which suits long documents, large codebases, or lengthy transcripts. It supports tool calling and reasoning; the listing does not state whether structured output is supported, so verify that before relying on schema-constrained responses. At $0.375 per million input tokens and $1.875 per million output tokens, it belongs on the shortlist for teams processing high volumes of multimodal or long-context input where cost per token matters. Its blended benchmark score of 67.8 rests on a single independent benchmark, so its standing against peers is only partly established. Test it on your own tasks before committing it to production.
