Qwen3 4B (Reasoning)
Analysis Summary
Qwen3 4B Reasoning is Alibaba's April 2025 compact reasoning model, priced at $0.11 input and $1.26 output per million tokens. With an intelligence index of 8.4, LiveCodeBench at 0.465, and MMLU-Pro at 0.696, it delivers strong coding and reasoning performance for its size and price point.
For businesses, it is well suited to cost-sensitive coding assistance, automated code review, and structured content tasks where budget is a primary constraint. The agentic index of 19 and tau2 of 0.190 suggest reasonable multi-step task capability. Instruction following (IFBench 0.325) is moderate, and long-context data is absent, limiting its fit for document-heavy workflows.
A -4 point regional penalty applies. At $0.11 per million input tokens, it offers strong value for coding-focused automation. Teams needing the best compact coding model at minimal cost should also evaluate the newer 2507 variant, which posts higher benchmark scores.
