Google: Gemini 2.5 Flash (batch)
The Google Gemini 2.5 Flash (batch) is a versatile AI model that supports multiple input modalities, including text, image, audio, video, and file inputs. It can handle long contexts of up to 1 megabyte in length and provides both reasoning capabilities and access to tools for further analysis. This model may be worth shortlisting for users with complex tasks or those who need to integrate data from various sources. With a blended benchmark score of 45.2 across three independent evaluations, it holds its own against other models. However, the high price point, with $1.25 per million output tokens and $0.15 per million input tokens, may deter users on a budget or those who only require simple tasks.
