[CITIC Securities: Optimistic About the Continued Rise of Domestic Large Models] DeepTech TechFlow reports that on October 19, CITIC Securities released a research report stating that Harness is expected to become a key component for DeepSeek in transitioning from model supply to a platform ecosystem, converting open-source and engineering advantages into user base, ecosystem influence, and commercialization capabilities. As Agent competition expands from model capabilities to stable, user-friendly, and cost-effective task delivery, DeepSeek is broadening its user and task coverage through plugin integration, scenario presets, and cross-Agent collaboration, extending its Infra advantage from software-hardware synergy to complete task execution. Its long-term value lies in ecosystem expansion to accumulate demand, solidifying configuration and process workflows to enhance product stickiness, and leveraging traceability to support security governance, collectively creating conditions for sustained usage and enterprise deployment. Beyond official model invocation, the company can also explore platform services and ecosystem transactions, converting ecosystem accumulation into more diversified revenue streams while supporting reinvestment in products and the ecosystem. Optimistic about the continued rise of domestic large models. (Jin10)
