Agent-centric architecture treats model as implementation detail; post-trains small open models for specialized sub-agents
The atomic unit is the agent (model + tools + prompts + environment), not the model. Specialized sub-agents (context retrieval, edit suggestion, debugging) are post-trained from open-weight…

Developers spend 90% of time reviewing agent-generated code; comprehension is new bottleneck
As coding agents generate >90% of code volume, the developer role shifts from writing to orchestrating and reviewing. Current code review tooling (file-by-file diffs) is inadequate for agen…

Chinese open-weight models (Kimi K2, Qwen Coder, GLM) lead in agentic tool use; US open ecosystem lagging
The most capable open-weight models for agentic tool use are now of Chinese origin. Application builders are post-training on these models for specialized sub-agents (search, editing, reaso…
