MoonshotAI: Kimi K2.5
Analysis Summary
Kimi K2.5 is MoonshotAI's penultimate flagship, with an intelligence index of 46.8 placing it in the excellent range. Its agentic score of 65.4 is strong, and it supports vision input alongside tool use and function calling across a 262K context window. Long-context reasoning and instruction following are both above average.
For businesses, this model suits agentic workflows, long-document analysis, and vision-augmented tasks. Its coding index of 39.6 is capable but not top-tier, so pure software engineering workloads may benefit from a more coding-focused alternative. The combination of vision, large context, and strong agentic performance makes it versatile for multi-modal business pipelines.
At $0.40 input and $1.90 output per million tokens, it is well priced for its capability level. Teams needing a high-context, agentic-capable model with vision support at a reasonable cost will find K2.5 a strong option, noting that K2.6 is the current benchmarked flagship in this family.
