Baidu is best known as a Chinese search and technology company, but its current AI ecosystem also includes the consumer assistant 文心 and the developer-focused Baidu AI Cloud Qianfan platform. Ordinary users can use 文心 to ask questions, search for information, rewrite text, summarize documents, create images and videos, work with files, generate presentations, and interact by text, voice, images, or video. Basic access is free with a Baidu account, while 文心一言 membership provides paid features whose exact pricing and benefits can vary. Qianfan is a separate usage-based platform for businesses and developers who need model APIs, Agents, tools, knowledge bases, customization, and deployment.
What is Baidu AI?
Baidu is a Chinese technology company founded in 2000 and headquartered in Beijing. Its products include search, cloud computing, artificial intelligence, and the ERNIE family of foundation models. For everyday users, the most relevant AI product is 文心, Baidu's consumer AI assistant, which was previously associated with the names 文心一言 and 文小言 in some versions and applications.
文心 is designed as a general-purpose assistant rather than a single-purpose chatbot. You can use it to ask questions, look for information, draft and rewrite Chinese text, summarize documents, create or edit images, generate videos, prepare presentations, and complete some multi-step tasks. It is closely connected to Baidu's wider services, including Baidu Search, which makes it especially relevant to Chinese-language users and people already using Baidu's ecosystem.
Baidu also offers Qianfan, formally Baidu AI Cloud Qianfan ModelBuilder, for developers and organizations. Qianfan provides access to Baidu ERNIE models and selected third-party models, along with tools for building applications and Agents. This developer platform is separate from the consumer 文心 membership service.
What can ordinary users do with 文心?
The consumer service covers several common AI tasks in one place. The exact features available to an account can change by application, region, device, and software version, but the current service supports a broad set of practical activities.
Ask questions, search, and research
You can ask 文心 questions in Chinese and use it to explore topics, explain concepts, compare options, or organize information. Its connection with Baidu Search supports search-oriented interactions and access to current information. Research-oriented features can also work with uploaded files and other sources, although the quality and availability of results depend on the query and the service configuration.
As with any AI search assistant, important facts should be checked against the underlying sources. A fluent answer is not automatically proof that every detail is correct, particularly when a question involves current events, legal matters, health, finance, or other high-consequence decisions.
Write and rewrite text
文心 can help draft, revise, summarize, and reorganize Chinese writing. Practical examples include turning notes into a structured message, changing the tone of a document, shortening a long passage, preparing an outline, or improving wording for work and study. This makes it useful for people who want a writing partner rather than a fully autonomous author.
The assistant can produce a first draft quickly, but users should still review names, numbers, citations, tone, and sensitive content before sharing the result.
Work with documents and files
File upload and document analysis allow users to ask questions about supplied material, summarize a document, extract key points, or turn source material into a more usable format. The service advertises support for text, voice, images, video, and documents in search and interaction workflows. It also supports integration with files from WeChat chat history in the relevant consumer applications.
For private or commercially sensitive files, check the current privacy terms before uploading. Availability of file features may vary between the web service, mobile applications, and PC client.
Create images, video, and voice interactions
文心 supports image generation and editing, image animation, and text-to-video generation. This can be useful for producing concept images, visual drafts, social content, or simple creative experiments. The service also offers voice and video conversations, voice input, and dialect recognition in supported contexts.
These features make 文心 more than a text-only chatbot. It can accept different kinds of input and, in some workflows, return non-text media such as images or video. The available models, quotas, generation quality, and editing controls may differ by product version and account entitlement.
Prepare presentations and complete tasks
The consumer service advertises PPT generation and task delegation. In practice, this means it can help turn a topic or source material into a presentation structure and can assist with multi-step activities. Task execution should be treated as supervised assistance: review the result, confirm important actions, and avoid assuming that every step has been completed exactly as intended.
Is Baidu AI free?
Basic access to Baidu's main consumer AI service is free with a Baidu account. The free service can provide access to conversational assistance and a selection of search, writing, file, and multimodal functions, but the precise limits and entitlements are not presented as a single globally standardized plan. They may vary according to the platform, region, account, application version, and current product arrangements.
Baidu also offers a paid 文心一言 membership. Official membership information indicates that monthly, quarterly, and annual service periods may be available. Paid membership can provide additional benefits or access, but the exact price, quota, model availability, and feature list should be checked in the current official purchase interface. Consumer membership pricing is separate from Qianfan developer billing.
This distinction matters because a free or paid consumer account is not the same thing as developer access. Someone who only wants to chat, write, search, or create media may not need Qianfan. Someone building an application should review Qianfan pricing and account requirements separately.
How to access Baidu AI
The consumer service is available through the 文心 website, mobile applications for iOS, iPadOS, and Android, and a PC client. A Baidu account is normally required for meaningful use, and membership services require an account. Access, payment options, supported features, and app availability can differ by device and region.
- Open the official 文心 website or install the official application.
- Sign in with or create a Baidu account where required.
- Start with a question, writing request, uploaded document, image, or voice interaction.
- Review the answer and refine your request if you need a different format, tone, or level of detail.
- Check the current membership and privacy information before subscribing or uploading sensitive material.
The main consumer service is oriented toward mainland China and Chinese-language users. People outside that market may encounter restrictions involving account registration, identity verification, payment, regional availability, application stores, or language support.
Baidu AI's main strengths
- Chinese-language performance: Baidu's services are built around Chinese-language search and communication, making the ecosystem a natural choice for many Chinese-speaking users.
- Search integration: The connection with Baidu Search supports information-seeking and research workflows rather than limiting the service to offline conversation.
- Broad media support: Users can work with text, images, documents, voice, video, and generated media in supported workflows.
- Practical productivity tools: Writing assistance, document summaries, PPT generation, file handling, and task-oriented features address common school, office, and personal needs.
- Large supporting ecosystem: Baidu combines consumer services with AI Cloud, ERNIE models, Qianfan, PaddlePaddle, and other technology products.
- Multiple access routes: Web, mobile, and desktop options make the consumer service available across common device types.
Important limitations and privacy considerations
Baidu AI is not equally convenient for every user. Its strongest fit is the Chinese market, and much of the product information, account process, and customer experience is primarily in Chinese. International users may find that access, payments, app availability, and model entitlements are less predictable than those of globally standardized services.
Product names and feature arrangements can change frequently. 文心, 文心一言, and related names may appear in different applications or product contexts. A feature advertised in one version may not be available in another. Subscription benefits and generation limits should therefore be checked at the time of use rather than assumed from an older description.
Privacy also deserves attention. The service operates through Baidu accounts and first-party websites and applications. App-store disclosures indicate that the application may collect or link content, identifiers, contact information, usage data, diagnostics, and other data depending on the features used. Baidu's terms describe circumstances in which information may be processed or disclosed as required by law or regulation, and membership terms may include commercial communications.
A clear current consumer-facing statement confirming that all conversations are either used or not used for model training was not verified. If you are handling confidential business information, personal records, unpublished work, or regulated data, read the current privacy policy and account settings before submitting it. The safest general practice is to share only the minimum information needed for the task.
Baidu Qianfan for developers and businesses
Qianfan is Baidu's developer and enterprise platform for model services and AI application development. It is not simply a premium chat screen. Developers can use it to select models, send text or multimodal requests, build Agents, connect tools and MCP services, integrate files and knowledge bases, customize models, evaluate applications, and deploy AI services.
An Agent is an application that can follow a workflow and use approved tools instead of only generating a reply. Qianfan also supports model services beyond the consumer 文心 experience, including ERNIE foundation and language models, multimodal models, image and video generation models, embedding-related services, selected open models, customized models, and Agent-oriented offerings.
Qianfan is primarily usage-based. Charges can include model-token usage and feature-specific services. Eligible new users may receive promotional quotas or coupons after registration and real-name verification; official documentation has described a 20 RMB coupon valid for one month, while product pages may advertise larger promotional token quotas in particular campaigns. These offers can change, so developers should verify current terms before budgeting.
Authentication generally uses Baidu Cloud access credentials and signed requests, although particular services may use their own authorization methods. Current Qianfan documentation includes API and SDK references, and selected Agent services provide OpenAPI and SDK access. Developers should use the current documentation because Baidu's platform has evolved from earlier Wenxin Workshop and Qianfan branding, and model identifiers, endpoints, pricing, and retirement policies may change.
Who should consider Baidu?
Baidu is a strong candidate for Chinese-speaking users who want search, writing, document assistance, media creation, and voice or video interaction in one ecosystem. It is particularly suitable for people already using Baidu services, for students and office workers handling Chinese material, and for users who want image and video tools alongside a conversational assistant.
Businesses and developers should consider Qianfan when they need access to Baidu's ERNIE models, multimodal services, Agents, knowledge integration, model customization, or deployment tools. Qianfan is a separate product decision from choosing the consumer assistant.
An alternative may make more sense for users who need broad international availability, transparent globally standardized pricing, strong documentation in a language other than Chinese, or clearly documented consumer memory and customization controls. Users with strict privacy or compliance requirements should also compare data policies carefully rather than choosing solely on feature count.
Practical assessment
Consider Baidu if you primarily work in Chinese, value Baidu Search integration, want one service for chat, documents, writing, voice, images, and video, or need access to a substantial Chinese AI and cloud ecosystem. Its strongest reasons to choose it are Chinese-language focus, multimodal tools, practical productivity features, and the connection between consumer services and Qianfan's developer platform.
The most important drawbacks are regional and language restrictions, changing product names and entitlements, limited transparency around globally consistent pricing, and the need to examine privacy terms before sharing sensitive information. A competing international assistant or specialist tool may be a better fit when worldwide availability, predictable plans, English-first documentation, or highly explicit data controls matter more than Baidu ecosystem integration.
