Qwen3 Technical Report
In this work, we present Qwen3, the latest version of the Qwen model family.
Qwen3 comprises a series of large language models (LLMs) designed to advance
performance, efficiency, and multilingual capabilities. The Qwen3 series
includes models of both dense and Mixture-of-Expert (MoE) architectures, with
parameter scales ranging from 0.6 to 235 billion. A key innovation in Qwen3 is
the integration of thinking mode (for complex, multi-step reasoning) and
non-thinking mode (for rapid, context-driven responses) into a unified
framework. This eliminates the need to switch between different models--such as
chat-optimized models (e.g., GPT-4o) and dedicated reasoning models (e.g.,
QwQ-32B)--and enables dynamic mode switching based on user queries or chat
templates. Meanwhile, Qwen3 introduces a thinking budget mechanism, allowing
users to allocate computational resources adaptively during inference, thereby
balancing latency and performance based on task complexity. Moreover, by
leveraging the knowledge from the flagship models, we significantly reduce the
computational resources required to build smaller-scale models, while ensuring
their highly competitive performance. Empirical evaluations demonstrate that
Qwen3 achieves state-of-the-art results across diverse benchmarks, including
tasks in code generation, mathematical reasoning, agent tasks, etc.,
competitive against larger MoE models and proprietary models. Compared to its
predecessor Qwen2.5, Qwen3 expands multilingual support from 29 to 119
languages and dialects, enhancing global accessibility through improved
cross-lingual understanding and generation capabilities. To facilitate
reproducibility and community-driven research and development, all Qwen3 models
are publicly accessible under Apache 2.0.
