How to Use

How to Use ERNIE Bot

Getting Started

Access ERNIE Bot: Visit yiyan.baidu.com in your browser, or download the ERNIE Bot app from your mobile app store.
Sign in with Baidu account: Log in with an existing Baidu account or register a new one. Basic features are free immediately after sign-in.
Choose a workspace: Select from Chat, Writing Desk, Document Hub, or Image Studio depending on your task type.
Enter your request: Type your question or task in the input box, or upload a file or image for analysis.
Switch model versions: Toggle between ERNIE 4.5 Turbo (faster) and ERNIE 5.0 (most capable) based on task complexity.
Enable DeepThink mode: For complex analytical questions, activate DeepThink·Auto for deeper, more thorough responses.

Tips and Best Practices

Use Writing Desk templates: Pre-built templates for business plans, marketing copy, and creative writing are faster than starting from scratch with a blank prompt.
Document analysis workflow: Upload a long document, ask for a summary first, then drill into specific sections with follow-up questions for more precise answers.
Image generation tips: Include style keywords (e.g., "Chinese ink painting style", "photorealistic") and specific details in your description for better image results.
Iterative multi-turn dialogue: For complex tasks, build up requirements across multiple turns rather than writing one long prompt — each turn refines the previous output.
Chinese-first tasks: ERNIE Bot performs best on Chinese content creation, Chinese cultural topics, and China-specific regulatory or policy questions.

Other Info

Additional Information

History: ERNIE Bot officially launched on March 16, 2023, as Baidu's response to the global AI assistant wave sparked by ChatGPT. Initially available to limited beta users, it opened to the general public in August 2023. Baidu has since released ERNIE 3.5, 4.0, 4.5 Turbo, and ERNIE 5.0 in rapid succession.

Technology: The ERNIE (Enhanced Representation through kNowledge IntEgration) model family has been in development since 2019. It incorporates Baidu's massive Chinese knowledge graph into the pre-training process, giving it a structural advantage in Chinese language tasks compared to models trained primarily on English data.

Developer: Baidu, Inc. — China's largest search engine company, headquartered in Beijing. Baidu has deep roots in AI research spanning autonomous driving (Apollo), intelligent voice (DuerOS), and AI chips (Kunlun).

Data Privacy: ERNIE Bot complies with China's Personal Information Protection Law (PIPL) and Data Security Law. User data is stored on servers within China. Users can manage and delete conversation history in account settings.

Competitive Landscape: Compared to ChatGPT and Claude, ERNIE Bot has stronger Chinese language capabilities but weaker English and international coverage. Among Chinese AI assistants, it competes with Tongyi Qianwen (Alibaba), Kimi (Moonshot AI), and Doubao (ByteDance), each with different strengths.

Supported Languages: Primarily optimized for Simplified Chinese, with support for English and other major languages. Performance is strongest in Chinese-language contexts.
