Deep dive

On shared benchmark coverage, Massive Multitask Language Understanding has Phi-4 14B at 84.8 and Qwen1.5-110B at 78.2, with Phi-4 14B ahead by 6.6 points. The largest visible gap is 6.6 points on Massive Multitask Language Understanding, 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 is close: both models cover structured outputs. That makes context budget, benchmark fit, and provider maturity more important than a simple checklist. If your application depends on one integration detail, verify it against the provider route you plan to use, not just the base model listing.

For cost, Phi-4 14B lists $0.07/1M input and $0.14/1M output tokens, while Qwen1.5-110B lists $1.5/1M input and $2.5/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Phi-4 14B lower by about $1.71 per million blended tokens. Availability is 3 providers versus 2, so concentration risk also matters.

Choose Phi-4 14B when provider fit, lower input-token cost, and broader provider choice are central to the workload. Choose Qwen1.5-110B when provider fit are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
