Google: Gemini 3.5 Flash

Gemini 3.5 Flash is a Google model that accepts text, image, video, audio, and file inputs, so a single endpoint can cover 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 extended transcripts. It supports tool calling and reasoning; structured output support is not specified in the available data, so teams that depend on strict schemas should test it first. Pricing is $1.50 per million input tokens and $9.00 per million output tokens. The input rate makes large-context ingestion relatively affordable, while output-heavy tasks will cost more. It belongs on the shortlist for buyers who need broad modality coverage and a very large context window in one model. It currently has no independent benchmark coverage, so its quality relative to alternatives is unproven; run your own evaluations on representative tasks before committing.
