Qwen1.5 110B — Hardware Requirements & GPU Compatibility
ChatQwen1.5-110B is Alibaba's largest dense base model in the Qwen1.5 series, a pretrained language model that is not instruction-tuned, released as a beta preview ahead of Qwen2. Like the rest of the Qwen1.5 line it uses a SwiGLU Transformer with an improved multilingual tokenizer, and at 110B it is one of only two sizes in the series, alongside 32B, to include grouped-query attention. A matching aligned chat model was released alongside it. At 111 billion parameters it requires a multi-GPU workstation or server to run, even quantized. Context length is 32,768 tokens. It is released under Alibaba's custom Tongyi Qianwen license, which permits commercial use below 100 million monthly active users. It was published in April 2024; Qwen1.5 has since been superseded by the Qwen2, Qwen2.5, and Qwen3 series.

Frequently Asked Questions
- How much VRAM does Qwen1.5 110B need?
Qwen1.5 110B requires 67.7 GB of VRAM at Q4_K_M, or 223.4 GB at BF16. Full 33K context adds up to 10.1 GB (77.8 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 111.2B × 4.8 bits ÷ 8 = 66.7 GB
KV Cache + Overhead ≈ 1 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 11.1 GB (at full 33K context)
