Kimi Developer on Agent Harness Evolution: Co-evolving with Model Intelligence
dotey · x · 2026-08-10
A core developer involved in training Kimi K2.5 delves into the nature of AI Agent frameworks and their relationship with evolving model capabilities.
- Framework Evolution: As model intelligence grows, harnesses don't disappear; they become more complex (e.g., introducing parallel tool calls, subagents, context compaction), enabling models to learn advanced interactions.
- Trade-offs: While stronger models simplify old mechanisms (like replacing subagents with direct bash calls), they unlock new interaction paradigms like proactive context rewind.
- Ultimate Integration: Analogous to human evolution where smarter brains created complex language, Agent frameworks will eventually merge with human social infrastructure, rewriting the entire SaaS ecosystem.
