Google: Gemini 2.5 Flash
Gemini 2.5 Flash from Google is designed for extensive interactions with a context length of up to 1048576 tokens and supports various input modalities including text, files, images, audio, and video. It also offers reasoning capabilities and can integrate tools for more versatile use cases. This model should be considered by those requiring robust multimodal handling and advanced reasoning; however, its blended benchmark score of 48.3 across three independent benchmarks indicates mixed performance.
