The Great AI Search Showdown: DeepSeek vs. Doubao vs. Kimi vs. Tongyi Qianwen

Introduction: The New Internet Gateway

Not long ago, if you had a question, you’d “Google it.” Today, you ask an AI.

According to QuestMobile data, in the first quarter of 2026, the average monthly active user base of AI-native apps in China reached 413 million, a year-on-year increase of 84.1%. By June 2026, China’s AI search user base had surpassed 700 million, with AI search penetration exceeding 68%. Nearly 70% of consumers now make purchasing decisions based on recommendations generated by AI platforms.

AI apps are becoming the new “gateway” to the internet — some people use them as search engines, others as photo editors, and many use them to write articles, build presentations, order food, and even replace traditional apps entirely.

Four platforms have emerged as the frontrunners in China’s AI search market:

• DeepSeek — the “STEM specialist” with the highest traffic
• Doubao — the “everyday companion” with the largest user base
• Kimi — the “deep research powerhouse” with the best search experience
• Tongyi Qianwen — the “ecosystem integrator” backed by Alibaba

Which one is the best “answer engine” for you? Let’s put them head-to-head.

The Contenders

1. DeepSeek — The “STEM Specialist”

Developer: DeepSeek (深度求索)
Monthly Website Visits (May 2026): 541 million — #1 in China, #5 globally
Monthly Active Users (App): ~127 million

DeepSeek has established itself as the go-to platform for technical and analytical work. Its strengths lie in mathematical reasoning, logical deduction, and code generation, with notably better control over hallucinations in professional content.

Key Features:

• Mode Layering: Introduced “Fast Mode” and “Expert Mode” in April 2026. Fast Mode handles daily conversations and instant responses with image and file text recognition. Expert Mode focuses on complex problems with deeper reasoning and intelligent search capabilities.
• Long-Chain Reasoning: DeepSeek’s strength lies in its long-chain reasoning and dynamic knowledge graphs, with the Expert Mode emphasizing reasoning transparency and domain depth to avoid “black box” outputs.
• Web Search Integration: Users can manually enable web search on the web version to fetch real-time news, data, stock prices, and weather.
• Chat History Search: Gray-tested chat history search functionality allows users to retrieve past conversations with fuzzy search and topic matching.

The Catch: DeepSeek lacks agent capabilities — it cannot generate mind maps or PPTs from extracted key points. In writing tasks, the Deep Think and Expert modes can take up to 6 minutes to generate just 180 characters. And like all AI models, it still hallucinates.

2. Doubao — The “Everyday Companion”

Developer: ByteDance
Monthly Active Users: ~345 million (June 2026)
Monthly Website Visits (May 2026): 164 million

Doubao (豆包) is ByteDance’s mass-market AI assistant — the one your parents might use. It’s not necessarily the smartest, but it’s the most reliable for everyday use.

Key Features:

• Stability: Doubao wins on consistency. Its answers are information-rich while being appropriately detailed, explaining complex concepts in an accessible way.
• Multimodal Creation: Strong in image and video generation, creative writing, and emotional engagement.
• Visual Recognition: Doubao’s video call recognition is a unique advantage — great for travel, object identification, and plant recognition.
• Clean Interface: Simple, clean design with powerful web search capabilities and accurate voice input.
• Task Mode: Launched in June 2026, this feature supports multi-round search, deep reasoning, browser automation, and multimodal content generation.

The Catch: Doubao lacks depth for complex research tasks. Some users have noted that the global search mixes chat, Q&A, image generation, and agents, making it harder to find specific content.

3. Kimi — The “Deep Research Powerhouse”

Developer: Moonshot AI (月之暗面)
Monthly Website Visits (May 2026): 46.08 million
Monthly Active Users: ~40-60 million

If you want the best AI search engine experience, Kimi is the consensus pick. It doesn’t dump all knowledge at once — in fast mode, it presents the most important explanation concisely with appropriate extensions, keeping the page uncluttered.

Key Features:

• Multi-Source Citation: When asked to find a report on Q1 2026 AI usage in China, Kimi cited up to 5 survey reports — more than any competitor — with each data point sourced and presented in clear tables.
• Information Refinement: Kimi’s answers are concise yet comprehensive. For example, when asked about the WHOOP fitness band, Kimi delivered a brief but refined answer that covered the product’s features in minimal time.
• Deep Reasoning Search: Kimi can break down complex problems into sub-questions and reason through them step by step, showing its chain-of-thought process.
• Agent Capabilities: Supports Kimi Claw, a zero-configuration cloud agent that runs 7×24 with long-term memory.
• Open-Source Models: Kimi K2.5, an open-source model, achieved top scores among global open-source models on multiple agent benchmarks.

The Catch: Kimi has a critical weakness — it frequently experiences “insufficient computing power” errors and is noticeably slower than competitors. For quick, everyday queries, Kimi can be frustratingly unreliable. It also struggles with “how-to” tutorials, often hallucinating incorrect steps.

4. Tongyi Qianwen — The “Ecosystem Integrator”

Developer: Alibaba
Monthly Active Users: ~80-165 million
Monthly Website Visits (May 2026): 44.28 million

Tongyi Qianwen (通义千问) is Alibaba’s AI play — and it’s the one that can actually do things for you, not just answer questions.

Key Features:

• Alibaba Ecosystem Integration: Qianwen is deeply integrated with Alibaba’s services. It can automatically book restaurant reservations through natural conversation. It’s integrated with Taobao’s 4 billion+ product catalog, allowing AI-powered conversational shopping.
• Agent Capabilities: Qianwen represents a shift from AI that “can talk” to AI that “can do”. It handles complex tasks like logistics management and after-sales service.
• Multimodal Understanding: Advanced cross-modal deep learning enables interpretation of data from charts, audio clips, and combined text-image inputs.
• Enterprise Stability: Qianwen offers the strongest operational stability for enterprise commercial deployment.

The Catch: The Qianwen app interface is crowded, with dense text formatting and relatively redundant answers that make it hard to extract useful information quickly. The answer quality, while仅次于 DeepSeek, suffers from poor readability.

5. Pricing & Accessibility

DeepSeek offers the best value with aggressive pricing (as low as $0.025 per million tokens for cache-hit input).

Kimi is the most expensive at approximately $0.74 per million input tokens and $3.50 per million output tokens — but offers open-weight models for self-hosting.

Doubao and Qianwen sit in the mid-range, with enterprise pricing available for commercial deployment.

Verdict: DeepSeek for cost-sensitive users; self-hosting changes the calculus for Kimi.

The Hallucination Warning

All five AI platforms hallucinate. In some cases, correct answers are ranked below incorrect ones; in severe cases, they provide completely wrong steps.

For tutorials involving personal safety — cooking, electrical work, medical advice — stick with human-powered platforms like cooking apps or social platforms.

Don’t fully trust or blindly believe any AI.
