Baidu's AI assistant powered by ERNIE 4.5 and X1 models. China's leading AI platform with deep Chinese language understanding, Baidu ecosystem integration, and API access. Free tier available, API from $0.28/1M tokens.
Baidu's Chinese AI assistant powered by the ERNIE (Enhanced Representation through Knowledge Integration) model.
Baidu Ernie Bot is an AI Chat assistant powered by the ERNIE 4.5 and ERNIE X1 reasoning models that delivers native-grade Chinese language understanding, Baidu ecosystem integration, and competitive multimodal capabilities, with consumer access available free and API pricing starting at $0.28 per 1M input tokens. It targets Chinese-language professionals, developers building for the China market, and global teams handling Chinese content.
Launched in March 2023 by Baidu (founded 2000), Ernie Bot reached over 300 million users by mid-2024 and was rebranded as Wenxiaoyan in 2024 alongside the launch of ERNIE 4.0. Based on our analysis of 870+ AI tools, it stands out as the only mainstream Chinese-native LLM platform with deep integration into Baidu Search, Baidu Maps, and Baidu Baike — giving it real-time access to China-specific data that ChatGPT, Claude, and Gemini routinely miss or hallucinate. ERNIE 4.5 delivers GPT-4 class performance on Chinese benchmarks, while ERNIE X1 challenges DeepSeek R1 on reasoning tasks at roughly half the cost.
For anyone working with Chinese language content, Chinese markets, or Chinese-speaking audiences, Ernie Bot offers advantages that Western AI models cannot match. Its training on massive Chinese internet content, academic papers, classical literature, and contemporary culture gives it an authentic understanding of Chinese linguistic nuances—idioms, classical references, regional variations, and modern internet slang—that ChatGPT and Claude handle adequately but not natively.
The integration with Baidu's ecosystem (Search, Maps, Baidu Baike) provides real-time access to Chinese-specific information that Western models often miss or get wrong: local business details, Chinese regulatory requirements, cultural event timing, and market dynamics.
Baidu's latest models compete directly with global frontrunners. ERNIE 4.5 delivers GPT-4 class performance on Chinese-language benchmarks while ERNIE X1, the reasoning-focused model, challenges DeepSeek R1 at dramatically lower costs—$0.28 per million input tokens versus DeepSeek's higher pricing. The models use progressive reinforcement learning to improve reasoning accuracy without the verbose chain-of-thought processing that inflates costs on competing platforms. For developers building Chinese-language AI applications, this price-performance ratio is compelling.
Consumer access is free at yiyan.baidu.com with a registered Baidu account. Developers can access the ERNIE model family through the Qianfan API platform with pay-per-token pricing starting at $0.28/1M input tokens for ERNIE X1 and $0.55/1M input tokens for ERNIE 4.5.
Ernie Bot is the definitive AI assistant for Chinese language and market applications. ERNIE 4.5 and X1 models deliver competitive performance at aggressive pricing, while deep Baidu ecosystem integration provides Chinese-specific capabilities Western models cannot match. Limited practical value for users outside Chinese-language contexts.
Trained on one of the largest Chinese-language corpora ever assembled—spanning contemporary internet content, classical Chinese literature, academic papers, and government documents. This gives Ernie Bot an authentic grasp of Chinese idioms, internet slang, regional expressions, and cultural context that Western models approximate but cannot fully replicate.
A dedicated reasoning model that uses progressive reinforcement learning to solve complex math, logic, and analytical problems. Unlike some competing reasoning models that produce verbose chain-of-thought outputs inflating token costs, X1 is designed to reason efficiently, delivering strong accuracy at an aggressive price point of $0.28 per million input tokens.
Connects directly with Baidu Search, Baidu Maps, Baidu Baike (China's leading encyclopedia), and other Baidu services to provide real-time, China-specific information. This allows Ernie Bot to answer questions about local businesses, current events, geographic data, and Chinese cultural knowledge with a level of accuracy and recency that standalone models cannot match.
Baidu's cloud-based API platform provides programmatic access to the full ERNIE model family with pay-per-token pricing. It supports fine-tuning, prompt engineering tools, model evaluation, and deployment pipelines, making it a comprehensive development environment for building Chinese-language AI applications at scale.
Beyond text conversation, Ernie Bot supports image generation and visual understanding within the consumer interface. Users can generate images from Chinese-language prompts and analyze uploaded images, making it a versatile creative and analytical tool for Chinese-speaking users who need both text and visual AI capabilities in one platform.

ERNIE X1 reasoning model launched in March 2025 to compete directly with DeepSeek R1 and OpenAI o1, priced at half of DeepSeek R1. ERNIE 4.5 was released the same month with multimodal capabilities and improved benchmark performance. Baidu announced plans to open-source the ERNIE 4.5 model series by mid-2025 and made the consumer Ernie Bot completely free (removing the prior ¥59.9/month subscription) to accelerate user growth amid competition from DeepSeek, Alibaba's Qwen, and ByteDance's Doubao.
