Google: Gemini 3.5 Flash (batch)

Google's Gemini 3.5 Flash (batch) is equipped with an extensive context length of 1048576 tokens and supports input modalities including text, images, videos, files, and audio. It also offers robust reasoning capabilities and the ability to handle tools, though it does not provide structured output. This model should be considered by those requiring a versatile AI that can process diverse inputs and engage in complex reasoning tasks; however, its higher price point of $0.75 per million input tokens and $4.5 per million output tokens may make it less suitable for budget-conscious projects. Its benchmark blended score of 84.3 across three independent benchmarks suggests strong performance but leaves room for improvement, especially in the agentic aspect as indicated by an AI Index sub-score of 65.5.
