Phi-4 Reasoning Vision 15B — 显存、速度与本地部署

作者: Jakub Rusinowski · 最后更新:

Microsoft's open multimodal reasoning model: the Phi-4-Reasoning language backbone joined to a SigLIP-2 vision encoder, 15B parameters in all. It takes text and images and decides per request whether to reason step by step before answering. MIT licence; the card states a 16,384-token context.

Phi-4 Reasoning Vision 15B 在 Q4_K_M 下约需 10 GB 显存——量化权重加框架开销,不含 KV 缓存。在 Apple Silicon 上,这部分来自统一内存。

按量化级别的显存与速度

计算基准:NVIDIA RTX 4090 (24 GB)。包含 8K 上下文的 KV 缓存,因此数值高于上方的主数字。

我的 GPU 能运行 Phi-4 Reasoning Vision 15B 吗?

Phi-4 Family 的其他尺寸

Phi-4 Reasoning Vision 15B — 常见问题

How much VRAM does Phi-4 Reasoning Vision 15B need?

About 10 GB at Q4_K_M — quantized weights plus framework overhead, before any KV cache. The cache grows with context length and is added on top; the table above folds it in. Apple Silicon counts unified memory toward the same figure.

Does Phi-4 Reasoning Vision 15B run on an RTX 4090 (24 GB)?

Yes. Phi-4 Reasoning Vision 15B needs about 10 GB at Q4_K_M, inside a 24 GB card, at an estimated 65 tokens/sec.

How do I run Phi-4 Reasoning Vision 15B locally?

Install Ollama and run `ollama run phi-4`. That pulls the weights and starts a local OpenAI-compatible endpoint; after the download nothing leaves the machine.

What other sizes does Phi-4 Family come in?

Phi-4 (14B) (9 GB), Phi-4 Reasoning Vision 15B (10 GB). Every size shares the family's training and licence; the larger ones score higher and need proportionally more memory.
