ERNIE X1

It competes with leading global models by combining high performance with cost‑effective pricing, making it suitable for developers, enterprise applications, and research use cases.

What Is ERNIE X1?

ERNIE X1 is a large language model optimized for “deep-thinking” reasoning: instead of emitting a quick pattern-matched answer, it decomposes tasks into intermediate steps, evaluates alternatives, and refines its final response. This makes it particularly strong for multi-step planning, complex coding, mathematical derivations, and logic-heavy workflows compared with conventional chat-focused LLMs.​

  • It is positioned as a high-efficiency reasoning model competing with systems like DeepSeek-R1 and OpenAI’s o3-style models, but at a significantly lower per-token cost in many scenarios.​
  • The model supports rich tool use, including search, document Q&A, image understanding and generation, code interpretation, and webpage analysis, enabling end-to-end intelligent agents and AI copilots.
 Тесты показывают, что модель Baidu Ernie X1 Turbo обеспечивает высокую производительность по сравнению с моделями-конкурентами, такими как Deepseek и OpenAI o1. Baidu также заявляет, что она значительно дешевле.

Key Capabilities

Reasoning and Problem Solving

ERNIE X1 is built to handle tasks that demand structured thinking rather than simple text continuation.​

  • Multi-step logical reasoning for puzzle-like tasks, decision trees, and chain-of-thought style problem solving in business, research, and engineering domains.​
  • Complex calculations and mathematical/statistical workflows, where the model can outline reasoning steps, intermediate results, and final answers for improved transparency.​

Coding, Debugging, and System Design

Beyond natural language, ERNIE X1 can act as a coding assistant and systems analyst.​

  • Code generation, refactoring, and debugging with explicit explanation of logic, design trade-offs, and error analysis.​
  • Support for multi-file reasoning and algorithmic problem solving, which makes it suitable for backend tools, developer copilots, and automated testing assistants.

Knowledge, Content, and Multimodal Understanding

ERNIE X1 is designed as a multimodal reasoning model, extending beyond plain text.​

  • Strong performance on Chinese and general-domain knowledge tasks, literary creation, manuscript drafting, summarization, and research assistance.​
  • Image understanding and generation, document Q&A, web-page reading, and mind mapping, letting developers build richer assistants and vertical domain copilots on top of a single reasoning core.

ERNIE X1 Turbo 32K API

ERNIE X1 Turbo 32K is a high-capacity variant designed to handle extremely long contexts of up to 32,000 tokens. This extended context window allows the model to process entire books, research papers, long transcripts, and multi-turn conversations without the need for artificial splitting. It is optimized for both inference speed and reasoning depth, making it ideal for tasks that require analyzing extensive content in a single pass.

Pricing:
  • $0.2145 per million input tokens
  • $0.858 per million output tokens

ERNIE X1.1 Preview API

ERNIE X1.1 builds on the original X1 architecture with improvements in factual accuracy, instruction compliance, and autonomous reasoning. Iterative learning frameworks and hybrid reinforcement learning techniques enhance the model’s ability to generate highly reliable outputs. ERNIE X1.1 has been benchmarked against leading global models, demonstrating competitive performance in reasoning-intensive tasks.

Pricing:
  • $0.2028 per million input tokens
  • $0.8151 per million output tokens

Use Cases

Multimodal Analysis for Specialized Sectors

The model’s ability to process both text and images makes it suitable for finance, legal, and healthcare industries. ERNIE X1 can interpret charts, tables, and documents, providing actionable insights from complex information sources.

Content Creation and Long-Form Writing

ERNIE X1 excels at generating long-form content, summarizing multiple documents, and synthesizing information. It enables publishers, researchers, and educational institutions to produce detailed analyses or concise summaries efficiently.

Extended Context Handling with Turbo 32K

The Turbo 32K variant allows the model to manage entire books, research papers, or complex multi-turn dialogues. It maintains context and coherence throughout long documents, making it ideal for high-volume content workflows.

Technical Assistance and Software Development

ERNIE X1 supports code generation, debugging assistance, and tool integration. This helps software teams accelerate development, solve problems efficiently, and streamline programming workflows.
