Baidu supplies new LLMS Ernie 4.5 and Ernie X1 undercutting Deepseek, Openai at a price – but they are not open code (still)

Over the weekend, the Chinese web Baidu search giant has announced the launch of two new AI, Ernie 4.5 and Ernie X1, multimodal language model and a reasoning model, respectively.

Baidu Claims They Offer State-Oof-Art Performance on a Variety of Metrics, Besting Deepeek’s Non-Reasoning V3 and Openai’s GPT-4.5 Third-Party Benchmark Tests Such As the C-EVAL (Assessing Chinese Llm Performance on Knowledge and Reasoning Across 52 Subjects), CMMLU (Massive Multitask Languing Undending words).

He also claims to undergo the price of the R1 reasoning model of Chinese Chinese Wunderkind with Ernie X1 with 50% and US AI Juggernaut Openai GPT-4.5 with Erney 4.5 to 99%, respectively.

Both have some important restrictions, including the lack of open code licensing in the first case (which the Deepseek R1 offers) and a far -reduced context compared to the second (8,000 tokens instead of 128,000, honestly, amazingly low in this age from million of the context.

As X User @Claudeglass noted in a post, the small context window makes it only suitable for customer service chatbots.

Baidu posted to X that he plans to make an open code of Family Ernie 4.5 on June 30, 2025.

Baidu has activated access to the models through its app interface (API) and a china rival to Chatgpt, known as « Ernie Bot » -Is answers questions, generates text, creates creative writing and interacts with users-and makes Ernie Bot free for access.

Ernie 4.5: A new generation of multimodal AI

Ernie 4.5 is the latest model of the BAIDU Foundation, designed as a local multimodal system capable of processing and understanding text, images, audio and video, and is a clear competitor to the Openai GPT-4.5 model launched in February 2025.

The model is optimized for a better understanding, generation, reasoning and memory. Improvements include improved prevention of hallucination, logical reasoning and encoding opportunities.

According to Baidu, Ernie 4.5 is superior to GPT-4.5 in multiple indicators, while maintaining a significantly lower price.

The progress of the model stems from several key technologies, including dynamic masking of FlashMask, a heterogeneous multimodal mixture of experts and improving training after training.

Ernie X1 introduces sophisticated possibilities for reasoning, emphasizing understanding, planning, reflection and evolution.

Unlike standard multimodal AI models, the Ernie X1 is specially designed for complex reasoning and use of tools, which allows it to perform tasks such as advanced demand based on Q&A, AI -generated, image interpretation, code execution and web pages analysis.

The model supports a number of tools, including Baidu academic search, business information and franchise research tools. Its development is based on the progressive strengthening of training, integration of end -to -end training and actions and a united multilateral remuneration system.

API access and availability

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

For users and developers of Enterprise, Ernie 4.5 is now available through the Baidu Ai Cloud Qianfan platform via API Access. Ernie X1 is expected to be available soon.

Pricing to access API:

• Ernie 4.5:
  • Login: $ 0.55 USD per 1 million tokens
  • Output: $ 2.2 per 1m tokens
• Ernie X1:
  • Login: $ 0.28 per 1m tokens
  • Output: $ 1.1 per 1m tokens

Compare this with:

• Deepseek R1
  • Login: $ 0.55 per 1m tokens
  • Output: $ 2.19 per 1m tokens

Baidu also announced plans to integrate Ernie 4.5 and Ernie X1 in its broader ecosystem, including Baidu Search and the Wenxiaoyan app.

Considerations for persons making decisions of the enterprise

For the teams of CIO, CTO, IT leaders and Devops, the launch of Ernie 4.5 and Ernie X1 presents both opportunities and considerations:

• Pricing – With pricing significantly more than competitive models, AI -evaluating organizations can see cost savings by integrating Ernie models via API. However, real-world comparison and testing may be needed to evaluate the effectiveness of specific business applications.
• Multimodal and reasoning – The ability to process and understand text, images, audio and video can be valuable to business in industries such as customer support, content generation, legal technology and finance.
• Integration -Ernie X1’s ability to work with tools such as advanced demand based on Q&A documents and codes interpretation can ensure automation and increasing efficiency in the corporate environment.
• Ecosystem and localization -At, like Baidu’s AI models, they are optimized for Chinese language processing and regional knowledge, businesses working in China or aimed at Chinese speaking markets can find Ernie models more effective than global alternatives.
• Licensing and privacy of data -Whid Baidu has indicated that the GPT-4.5 will be made with an open source later this summer, June 30, 2025, this is still three months, so businesses have to at least wait until then to decide whether it is worth it to deploy locally or on cloud services hosted in the US. Enterprise users must review Baidu’s policies on data privacy, conformity and use of the model before integrating these AI solutions.

AI extension and future perspective

As the AI ​​development is accelerated in 2025, Baidu is positioned as a leader in multimodal and reference -based AI technologies.

The company plans to continue investing in artificial intelligence, data centers and cloud infrastructure to improve the capabilities of its main models.

By offering a combination of powerful results and lower costs, Baidu’s latest AI models are intended to provide business and individual users more accessible and sophisticated AI tools.
