Qwen3 4B (Reasoning)
Analysis Summary
Qwen3 4B (Reasoning) is Alibaba's compact thinking-mode model, released in April 2025. With a GPQA of 0.522 and livecodebench of 0.465, it punches above its weight for a 4-billion-parameter model. Its agentic index of 19 is reasonable, and instruction-following (ifbench: 0.325) is adequate for structured tasks.
For businesses, it suits cost-sensitive workflows: SEO content drafting, structured data extraction, and lightweight reasoning tasks where a larger model would be overkill. Its coding capability is not benchmarked separately, and long-context data is absent, so it should not be relied upon for complex codebases or long-document analysis.
At $0.11 input and $1.26 output per million tokens, it is among the most affordable reasoning-capable models available. Teams running high-volume, lower-complexity tasks will find strong price-performance here, with the caveat that Alibaba's API accessibility may require additional integration work for enterprise environments.
