Kimi K2.5 Visual Agentic Release
Narrative
Native multimodal (vision + text) with 1T MoE architecture. Agent Swarm with up to 100 sub-agents and 1,500 tool calls. Open-source SOTA on HLE (50.2%), BrowseComp (74.9%), and SWE-Bench Verified (76.8%).
Reality
GPQA Diamond 88.0%, AIME 2025 96.1%. Artificial Analysis: new leading open-weights model, Elo 1309. Agent Swarm achieved 4.5x speedup over single-agent. API pricing $0.60/M input — fraction of proprietary alternatives.
Implication
Most capable open-source model to date. Agent Swarm paradigm introduced parallel agentic execution — architectural innovation beyond single-model scaling. Vision-code capabilities challenged proprietary multimodal leads.
