Refreshed 4B Qwen3 instruct model with 256K context and no-thinking fast mode.
About
Qwen3-4B-Instruct-2507 is Alibaba's July 2025 refresh of the 4B Qwen3 tier, released on July 21, 2025 alongside a Thinking-2507 sibling. It splits the original hybrid thinking design into a dedicated non-thinking instruct model tuned for general-purpose dialogue and instruction following, with a native 262,144-token context window.
Alibaba positions it as a compact model for developers who want strong instruction following and reasoning without the latency of an explicit chain-of-thought phase, supporting 100-plus languages under Apache 2.0. Checkpoints are on Hugging Face and work with standard Transformers tooling.
