The new frontier is agent efficiency. A high-efficiency Flash model for real-world agents. Multimodal Understanding & Action|Web & Visual Search Enhancement|Reliable Tool Use & Orchestration|Agent Ecosystem Compatibility GitHub HuggingFace ModelScope

Key Features Native Multimodal Understanding & Acting Understands images across the full range — product UIs, documents, charts, and natural scenes — then writes code or calls tools to act on what it sees. Web & Visual Search Enhancement Web search reaches further — more sources, deeper follow-up. Visual search recognizes what other systems don't — long-tail entities, freshly emerged concepts. Reliable Tool Use & Orchestration Drives terminals, browsers, Office tools, search, and beyond — staying coherent however long the run gets. Less drift, fewer broken toolcalls, fewer failed runs. Agent Ecosystem Compatibility Works with mainstream harnesses (Claude Code, KiloCode, Hermes Agent, OpenClaw) and Skills — lower integration cost, less workflow rewiring.
