Baidu delivers new LLMs ERNIE 4.5 and ERNIE X1 undercutting DeepSeek, OpenAI on cost — but they’re not open source (yet)

Weekend, Chinese website search giant Baidu Announced the launch of two new AI models, Ernie 4.5 and Ernie X1A multimodal language model and reasoning model, respectively.

Baidu, the most modern performance in the most modern sizes, the best, the most foolish v3 and Openai’s GPT-4.5 (How do you like Baidu “How do you like Baidu Baidu?) A few third-party tests like Csalon (Assessing the knowledge and thinking between 52 subjects of Chinese LLM performance), CMMLU (Massive language of massive language in Chinese) and Gsm8k (Mathematics word problems).

Also claims that peers have passed the value of Chine Wunderkindin Deepseek’s R1 Justification Model 50% with Ernie X1 and the US AI Juggernnaut Openai’s GPT-4.5 Ernie 4.5 with 99% respectively.

It is more info, both with more information, more information, more information, which is more information, more information, more information, more information, and the lack of open source license) and is the most reduced context. 250-page novel).

Baidu Sent x On June 30, 2025, Ernie 4.5 model said that the family planned to make an open source.

Baidu, the Applied Programming Interface (API) and Chinese-speaking Chatbot gave access to models, including ChatGpt, known for the opponent “Ernie Bot“- answers questions, creates text, creates creative writing and conversations with users and are free with users.

Ernie 4.5: A new generation of Multimodal Ai

Ernie 4.5 is the last basic model of Baidu, the ability to process and understand text, pictures, audio and videos and is a clear opponent Openai’s GPT-4.5 model was released in February 2025.

The model is optimized for better understanding, generation, justification and memory. Discounts include improved hallucination prevention, logical justification and encoding capabilities.

According to Baidu, Ernie 4.5 is superior to GPT-4.5 in numerous criteria when protecting a significant low price.

The progress of the model is to develop a few main technologies, including flashmask dynamic focus mask, heterogeneous multimodal mixture and post-feedback education.

Ernie X1 provides advanced deep thinking capabilities that emphasize the concept, planning, reflection and evolution.

Unlike standard multimodal AI models, Ernie X1 is designed specifically for the use of complex thinking and tool that allows you to perform tasks such as advanced search, document-based image interpretation, code execution and web page analysis.

The model supports a number of tools, including Baidu’s academic search, business information search and franchise research tools. Its development is based on trainings, thinking and chains and chains of thinking and movement and a single versatile premium system.

Access and API availability

Users can now access Ernie 4.5 and Ernie X1 through the official Ernie Bot website.

ENTERPRise users and Ernie 4.5 available for developers Baidu AI cloud’s Qianfan Platform with API access. Ernie X1 is expected to be available soon.

Price for API access:

• Ernie 4.5:
  • Introduction: $ 0.55 for 1 million Token
  • Exit: $ 2.2 for $ 1 million tokens
• Ernie X1:
  • Introduction: $ 0.28 per $ 1 million
  • Output: $ 1.1 for $ 1 million

Compare it:

• DeepSeek R1
  • Introduction: $ 0.55 for $ 1 million tokens
  • Output: $ 2.19 for 1 m tokens

Baidu also planned to integrate Ernie 4.5 and Ernie X1 to a wider ecosystem, including Baidu search and Wenxiaoyan application.

Considerations for enterprise decisions

For CIOS, CTOs, IT leaders and Devops teams, Ernie 4.5 and Ernie X1 launches both opportunities and considerations:

• Performance vs. – Organizations that evaluate the AI ​​solutions from competing models, the organizations that assess the AI ​​solutions can be combined with the API and see expenditures by combining Ernie models. At the same time, the more benchmarking and real world tests may need to evaluate performance for special job applications.
• Multimodal and the ability to think – Can be valuable for businesses such as ability to process and understand text, pictures, audio and videos, customer support, content production, legal technology and finance.
• Instrument integration – Ability to work with tools such as advanced search, document-based Q & A, and code interpretation of Ernie X1, can provide automation and efficiency profits in the enterprise environment.
• Ecosystem and localization – Baiyu’s AI models can find Ernie models that are more effective in Chinese-language processing and regional knowledge, businesses or Chinese-speaking markets, more effective than global alternatives.
• Privacy of licensing and data – Baidu said GPT-4.5 would be opened in this summer after June 30, 2025, so the enterprises should wait for the placement of cloud services in a local or US. Before integrating this AI solutions, enterprise users should consider Baid’s policy on the use of the data confidentiality and model.

AI expansion and future outlook

As the AI ​​development accelerated in 2025, Baidu places itself as a leader in multimodal and motivated AI technologies.

The company plans to continue to invest in artificial intelligence, information centers and cloud infrastructure to increase the capabilities of basic models.

By offering a combination of strong performance and low costs, Baidu’s latest AI models aims to provide enterprises and individual users with more accessible and advanced AI tools.
