The provided sources detail the Qwen3 model family, a new iteration of large language models developed by the Qwen Team. A primary focus is Qwen3-Coder, an advanced code model featuring "agentic" capabilities for coding and browser/tool use. The Qwen3 series introduces a unique unified framework with "thinking" and "non-thinking" modes, allowing dynamic resource allocation for reasoning, alongside a "thinking budget" mechanism. Pre-trained on an expanded 36 trillion token dataset spanning 119 languages, Qwen3 models, including both dense and Mixture-of-Expert architectures, demonstrate state-of-the-art performance across diverse benchmarks, particularly in code generation, mathematics, and agent tasks, significantly outperforming predecessors and competitive open-source models while being comparable to leading proprietary models.
