What Does DeepSeek’s 2025 AI Report Reveal About the Future of Large Models?

The 2025 DeepSeek Insight and Large‑Model Application Report examines the development of DeepSeek’s large‑model portfolio, evaluates the broader AI landscape, and offers practical guidance for model users.

DeepSeek’s Model Line‑up

DeepSeek, a subsidiary of Huifang Quantitative founded in May 2023, launched DeepSeek‑V3 on 26 December 2024. Positioned against GPT‑4o, V3 delivers lower training costs and strong performance, matching top‑tier closed‑source models in several benchmarks. In January 2025 DeepSeek‑R1, aimed at GPT‑o1, entered the market and quickly became the best‑performing open‑source model.

US‑China AI Landscape Comparison

China lags the United States in the number of high‑end AI talent and in the volume of original breakthroughs. At the corporate level, U.S. tech giants hold larger market capitalisations and host more AI unicorns with higher valuations. In GPU hardware, U.S. firms maintain a clear advantage, while domestic chips have improved but still trail. Nevertheless, Chinese models have narrowed the performance gap, with DeepSeek standing out in the open‑source arena.

Key Application Scenarios

Large models are being deployed across many sectors:

Government hotlines – improving ticket‑handling efficiency and data completeness.

Economic decision‑making – assisting authorities in analysing macro‑economic data.

Public security – enhancing video investigation capabilities.

Medical assistance – supporting healthcare professionals.

Ship design, large‑aircraft operation and maintenance, cultural‑creative projects – driving innovation through model‑enabled solutions.

Practical Usage Recommendations

Models still suffer from hallucinations, high compute consumption, slow knowledge updates, bias and safety risks. Users should verify outputs, understand model limits, accept slower response times, enable internet search when needed, avoid feeding sensitive or confidential information, and master effective prompting techniques.

Overall, DeepSeek’s rapid model development is reshaping the AI market; despite existing challenges, continued advances are expected to expand model impact across more domains.
