Deep mode

Deep thinking does not guarantee that the conclusions are correct; the reasoning process and the assumptions used still need to be examined.

AI writing

Personal knowledge base

A personal knowledge base is used to store information in a centralized manner, with AI facilitating the retrieval and summarization of content.

• Split the knowledge base by project or topic.
• Remove passwords and sensitive personal information before uploading.
• Use clear names and version dates for files.
• When asking questions, responses are limited to those based on the knowledge base.
• The answer is required to indicate the corresponding file and paragraph.
• Update old files to avoid mixing old and new rules.

Shared knowledge base

The shared knowledge base offers access to public or topic-specific materials, making it convenient to gain a quick understanding of particular subjects.

• First, confirm the creator and update time of the knowledge base.
• It is important to return to the authoritative original sources for verification.
• Do not assume that all shared materials can be used for commercial purposes.
• Be cautious when citing content that is expired or incorrect.
• Personal and corporate secrets should not be placed in public knowledge bases.

AI image and video generation

• The prompt should specify the subject, scene, composition, and style.
• Authorization must be obtained before using character and brand materials.

• When published publicly, indicate that it was generated by AI in accordance with the platform’s rules.
• It is forbidden to create false evidence or pretend to be real people.
• Verify the terms of use for materials and models before commercial use.

Agents and AI Plaza

Agents are used to encapsulate specific roles, prompts, and tools; AI Plaza enables the discovery of assistants for various purposes.

• Select an agent that matches the task domain.
• View the creator, description, and required permissions.
• Do not submit sensitive information to unknown entities.
• Treat the output as an auxiliary result rather than a professional conclusion.
• The capabilities and limits of public agents can be adjusted at any time.

Incognito mode

Incognito mode is suitable for temporary conversations that one does not want to be kept in the regular history.

It should not be understood as meaning that devices, networks, and servers never process any data at all.

• Do not enter a password, key, or identification documents yet.
• Confirm that no sensitive copies will be left before saving the results.

Accounts and Privacy

According to the privacy policy, registering for and logging in to generative AI services requires a mobile phone number and a verification code.
