Baidu Ernie 4.5 and X1: How China’s AI Innovations Are Outpacing Global Rivals
As Western tech giants grapple with soaring AI development costs, Chinese powerhouse Baidu has launched a strategic offensive with two groundbreaking models: Ernie 4.5 and Ernie X1. These releases mark a pivotal shift in the global AI race, combining cutting-edge capabilities with unprecedented pricing that undercuts competitors by 99%. Here’s how Baidu is rewriting the rules of artificial intelligence.
Baidu’s AI Ambition: From Search Engine to Global AI Leader
Once known as “China’s Google,” Baidu has aggressively pivoted to AI, investing $1.4 billion annually in R&D since 2019. While early attempts like Ernie Bot faced adoption challenges against rivals like Alibaba’s Qwen, the company’s latest models signal a matured strategy:
Dual-Model Approach: Ernie 4.5 (multimodal generalist) + Ernie X1 (specialized reasoning)
Ecosystem Integration: Embedded across Baidu Search, Maps, and Wenxiaoyan productivity app
Price Warfare: Models priced at 1% of OpenAI’s GPT-4.5 rates
Ernie 4.5: A Multimodal AI Powerhouse
Ernie 4.5 is Baidu’s latest general-purpose AI model, built with advanced multimodal capabilities to process text, images, audio, and video seamlessly. Its core strengths include:
Enhanced reasoning and logical capabilities
Improved contextual understanding and memory retention
Superior multimodal integration for image, video, and text comprehension
Cutting-Edge Features of Ernie 4.5
Ernie 4.5 introduces innovative AI techniques, such as:
FlashMask Dynamic Attention Masking
Heterogeneous Multimodal Mixture-of-Experts
Spatiotemporal Representation Compression
Knowledge-Centric Training Data
Self-Feedback Enhanced Post-Training
These advancements allow Ernie 4.5 to excel in tasks requiring deep understanding, such as recognizing internet memes, satire, and complex logical structures.
Cost-Effective AI That Outperforms the Competition
One of the most disruptive aspects of Ernie 4.5 is its affordability. Baidu claims it outperforms GPT-4.5 while being 99% cheaper:
CNY 0.004 per 1,000 input tokens (~$0.55 per million tokens)
CNY 0.016 per 1,000 output tokens (~$2.20 per million tokens)
This pricing model significantly undercuts OpenAI’s offerings, making advanced AI more accessible to enterprises and developers.

Ernie X1: Baidu’s Specialized Reasoning AI
Unlike Ernie 4.5, Ernie X1 is designed specifically for reasoning-intensive applications, excelling in logical inference, complex problem-solving, and decision-making. Key features include:
Advanced knowledge-based question answering
Manuscript writing and literary creation
Multimodal integration for documents, code, and data interpretation
Enhanced logic processing for finance, law, and analytics
Transparent AI Reasoning with Chain-of-Thought (CoT)
Ernie X1 leverages progressive reinforcement learning and an end-to-end training approach, ensuring structured decision-making with a visible chain of thought. This makes it highly reliable for applications requiring critical reasoning.
How to Access ERNIE 4.5 and ERNIE X1
Baidu has further expanded accessibility by making Ernie Bot completely free, accelerating adoption and user feedback collection. Additionally, the company has announced plans to open-source Ernie 4.5 by June 30, 2025, allowing developers worldwide to leverage its technology.
You can directly try Baidu’s ERNIE 4.5 and X1 through the official chatbot application available on their website: yiyan.baidu.com.
However, based on my personal experience, there are a few usability issues. The interface is currently available primarily in Chinese, making it challenging for non-Chinese speakers—while you can use the browser’s automatic translation feature, the translation is not smooth, and the UX suffers.
Additionally, Google or GitHub login is unavailable, a problem I haven’t encountered with competitors like DeepSeek or Qwen. I still tried to create an account, but I wasn’t allowed to complete the registration form with my European phone number.
Accessing ERNIE via API
For developers interested in integrating ERNIE 4.5, API access is already available via Baidu’s official platform, Qianfan.
Challenges in Global Accessibility
Despite its impressive AI capabilities, Baidu’s models face limitations in international adoption. The platform is primarily available in Chinese, lacks common authentication methods like Google or GitHub login, and restricts access to Chinese phone numbers. Unless these barriers are addressed, Baidu’s impact may remain concentrated in Chinese-speaking markets.
The Future of AI: How Baidu is Disrupting the Industry
Baidu’s Ernie 4.5 and X1 represent a seismic shift in AI affordability and capability. By offering competitive models at a fraction of the cost, Baidu challenges Western AI dominance and reshapes market expectations. While international accessibility remains a hurdle, the company’s aggressive pricing and technical advancements position it as a formidable player in the AI space.
Will Baidu’s AI Revolution Extend Beyond China?
As Baidu refines its AI ecosystem and expands accessibility, its disruptive approach could influence AI pricing and adoption worldwide. Whether it can overcome international accessibility challenges remains to be seen, but one thing is clear—Baidu is setting new benchmarks for AI performance and affordability.
Final Thoughts
Baidu’s AI expansion is a game-changer, offering businesses and developers unprecedented access to high-quality AI at unbeatable prices. Whether you’re an enterprise looking for cost-effective AI solutions or an AI enthusiast tracking industry trends, Baidu’s Ernie 4.5 and X1 are models to watch in 2025 and beyond.
