MoonshotAI: Kimi K3
The Kimi K3 from MoonshotAI is an AI model that supports three input modalities: text, image, and video. It has a context length of 1 megabyte and can handle up to 943,718 completion tokens. This model may be worth shortlisting for users who require a versatile AI tool that can handle multiple data types and perform reasoning tasks. Its blended benchmark score is 96.2 across three independent benchmarks, but its pricing may not justify its use for all applications: at $3.0 per million input tokens and $15.0 per million output tokens, it is more expensive than some other models.
