DeepSeek-OCR 3B — 显存、速度与本地部署
作者: Jakub Rusinowski · 最后更新:
All 3B parameters stay resident — about 2.6 GB at Q4_K_M, so it runs on effectively any modern GPU — while the MoE decoder activates 6 of 64 routed experts plus 2 shared, roughly 570M parameters per token. Token budgets are explicit and chosen per page: Tiny 64 tokens at 512x512, Small 100 at 640x640, Base 256 at 1024x1024, Large 400 at 1280x1280, and a Gundam mode composing several 640x640 views with one 1024x1024 global view. 8,192-token sequence length.

DeepSeek-OCR 3B 在 Q4_K_M 下约需 3 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)。仅含权重与开销:该模型架构未公开,因此未计入 KV 缓存。

DeepSeek-OCR 3B — 常见问题
How much VRAM does DeepSeek-OCR 3B need?
About 3 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 DeepSeek-OCR 3B run on an RTX 4090 (24 GB)?
Yes. DeepSeek-OCR 3B needs about 3 GB at Q4_K_M, inside a 24 GB card, at an estimated 307 tokens/sec.
How do I run DeepSeek-OCR 3B locally?
Install Ollama and run `ollama run deepseek-ocr`. That pulls the weights and starts a local OpenAI-compatible endpoint; after the download nothing leaves the machine.
