DeepSeek-VL2
DeepSeek-VL2 is DeepSeek's second-generation open vision-language model family, released in December 2024. Built on the DeepSeekMoE sparse-MoE backbone, the three variants — Tiny (3B total / 1B active), Small (16B / 2.8B) and base VL2 (27B / 4.5B) — combine high parameter counts with efficient inference. A dynamic tiling strategy enables fine-grained high-resolution understanding, and a VL-specific multi-head latent attention cuts KV-cache cost on long image+text sequences.

Frequently asked questions
What is DeepSeek-VL2?
DeepSeek-VL2 is an open mixture-of-experts vision-language model family (Tiny / Small / base) released by DeepSeek in December 2024, with strong OCR and grounding performance.
Why MoE for a VLM?
MoE lets the model be parameter-rich (up to 27B total) while activating only a few billion parameters per token, giving better quality per inference FLOP on long image+text sequences.
Is DeepSeek-VL2 open source?
Yes — weights are on Hugging Face under the DeepSeek community licence, usable for research and most commercial applications.
