Deep dive
On shared benchmark coverage, MMMU Pro has Phi 4 Multimodal Instruct at 38.5 and Qwen3.5-122B-A10B at 76.9, with Qwen3.5-122B-A10B ahead by 38.4 points. The largest visible gap is 38.4 points on MMMU Pro, 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 reasoning mode: Qwen3.5-122B-A10B, function calling: Qwen3.5-122B-A10B, tool use: Qwen3.5-122B-A10B, and structured outputs: Qwen3.5-122B-A10B. Both models share vision and multimodal input, 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 Multimodal Instruct lists $0.90/1M input and $0.90/1M output tokens on the cheapest tracked provider, while Qwen3.5-122B-A10B lists $0.26/1M input and $2.08/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Qwen3.5-122B-A10B lower by about $0.09 per million blended tokens. Availability is 3 providers versus 3, so concentration risk also matters.
Choose Phi 4 Multimodal Instruct when vision-heavy evaluation are central to the workload. Choose Qwen3.5-122B-A10B when reasoning depth, larger context windows, and lower input-token cost are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
