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?

Phi-4 Mini is cheaper on tracked token pricing. Phi-4 Mini costs $0.05/1M input and $0.15/1M output tokens. Qwen1.5-7B costs $0.05/1M input and $0.25/1M output tokens. Provider discounts or batch pricing can still change the final bill.

Is Phi-4 Mini or Qwen1.5-7B open source?

Phi-4 Mini is listed under Microsoft Research. Qwen1.5-7B is listed under Apache 2.0. License labels affect whether you can self-host, redistribute weights, or rely only on hosted APIs, so confirm the upstream license before deployment.

Which is better for structured outputs, Phi-4 Mini or Qwen1.5-7B?

Qwen1.5-7B has the clearer documented structured outputs signal in this comparison. If structured outputs is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.

Where can I run Phi-4 Mini and Qwen1.5-7B?

Phi-4 Mini is available on Fireworks AI, NVIDIA NIM, and Novita AI. Qwen1.5-7B is available on Alibaba Cloud PAI-EAS, Cloudflare Workers AI, Together AI, and Replicate API. Provider coverage can affect latency, region availability, compliance posture, and fallback options.

When should I pick Phi-4 Mini over Qwen1.5-7B?

Pick Qwen1.5-7B for reasoning; Phi-4 Mini is better when provider fit matters more. If your workload also depends on provider fit, start with Phi-4 Mini; if it depends on provider fit, run the same evaluation with Qwen1.5-7B.
