Core Capabilities

Enhanced Logic and Reasoning Abilities: An advanced Thinking mechanism has been introduced, enabling the model to better handle logically complex, multi-step planning tasks through internal reasoning processes, significantly improving the accuracy and factual reliability of its outputs.

Native Multimodal Support: It fully supports various input formats, including text, images, videos, audio, and PDFs, allowing it to quickly extract core information from massive heterogeneous data and achieve true deep multimodal understanding.

Agent Task Expert Optimization: Specifically designed for complex agent scenarios, this version boasts outstanding tool invocation capabilities (supporting Function Calling and custom tools), delivering more reliable and precise performance in multi-step task execution within real-world business environments.

Massive Context Handling: By default, it supports an ultra-long context window of up to 1 million tokens, easily handling ultra-long document processing, complex codebase comprehension, and large-scale project data analysis.
