Standout strengths

Gemini

  • True multimodality

    Understands and reasons across text, images, audio, and video together, not as separate add-ons.

    The Pro tier supports up to 2 million tokens, among the largest context windows of any mainstream model.

  • Fast, affordable tier

    The Flash tier delivers most of the flagship quality at a fraction of the speed and cost.

Kimi

  • 1M-token context window

    Reads entire books, research papers, or codebases in a single pass without losing track.

  • Fast decoding at scale

    A hybrid attention mechanism keeps long-context responses fast instead of slowing to a crawl.

  • Native vision understanding

    Combines strong vision and language understanding in one model, not a separate add-on.
