Deep dive
On shared benchmark coverage, Google-Proof Q&A has Phi-4 Mini at 25.2 and Qwen1.5-7B at 42.5, with Qwen1.5-7B ahead by 17.3 points; Massive Multitask Language Understanding has Phi-4 Mini at 67.3 and Qwen1.5-7B at 69.4, with Qwen1.5-7B ahead by 2.1 points. The largest visible gap is 17.3 points on Google-Proof Q&A, which matters most when that benchmark mirrors your workload. Treat isolated benchmark wins as directional, because provider routing, prompt style, and tool access can move real application results.
The capability footprint differs most on structured outputs: Qwen1.5-7B. Both models share the core language-model surface, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
For cost, Phi-4 Mini lists $0.05/1M input and $0.15/1M output tokens, while Qwen1.5-7B lists $0.05/1M input and $0.25/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Phi-4 Mini lower by about $0.03 per million blended tokens. Availability is 3 providers versus 4, so concentration risk also matters.
Choose Phi-4 Mini when provider fit are central to the workload. Choose Qwen1.5-7B when provider fit and broader provider choice are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
FAQ
Which is cheaper, Phi-4 Mini or Qwen1.5-7B?
