Gemma 4 vs Phi-4 Reasoning Vision 15B

Choose Gemma 4 if…

Best for developers building local or self-hosted assistants who can manage deployment, evaluation, and data handling, and its edge is five deployment options: E2B, E4B, 12B Unified, 26B A4B MoE, and 31B Dense, with audio input on the three smaller dense variants. Choose Gemma 4 when control over model deployment matters and you can support the infrastructure; it is not a managed assistant subscription. Lean toward Phi-4 Reasoning Vision 15B instead if combines a reasoning-tuned backbone with a vision encoder in a single 15B open-weight model, able to read documents and images while solving multi-step problems matters more for your use case.

Choose Phi-4 Reasoning Vision 15B if…

Best for developers who need document and image understanding plus multi-step reasoning, and are willing to check their own hardware's memory and runtime against Microsoft's tested configurations (A6000 through B200) before deploying, and its edge is combines a reasoning-tuned backbone with a vision encoder in a single 15B open-weight model, able to read documents and images while solving multi-step problems. Evaluate Phi-4 Reasoning Vision 15B for image/document reasoning on infrastructure you control; verify memory and runtime needs for the chosen configuration. Lean toward Gemma 4 instead if five deployment options: E2B, E4B, 12B Unified, 26B A4B MoE, and 31B Dense, with audio input on the three smaller dense variants matters more for your use case.
