Common questions
DeepSeek V3 vs Qwen 2.5 7B: which is bigger?
DeepSeek V3 has more parameters (DeepSeek V3: 671 B; Qwen 2.5 7B: 7 B). More parameters usually means higher ceiling on capability and higher memory requirement, though MoE architectures decouple total parameters from per-token compute.
DeepSeek V3 vs Qwen 2.5 7B: which is newer?
DeepSeek V3 released 2024-12-26; Qwen 2.5 7B released 2024-09-19.
DeepSeek V3 vs Qwen 2.5 7B: which needs less memory to serve?
Qwen 2.5 7B needs less HBM. Weights-only footprint at FP16: DeepSeek V3 1342 GB; Qwen 2.5 7B 14 GB. Half those numbers at INT8, quarter at INT4. Real serving adds 10-30% for KV cache.
DeepSeek V3 vs Qwen 2.5 7B: which license is more permissive?
DeepSeek V3: MIT. Qwen 2.5 7B: Apache 2.0. Apache 2.0 and MIT allow unrestricted commercial use; Llama Community License allows commercial use but restricts training larger models on outputs; CC-BY-NC and vendor-specific licenses (Qwen 72B, Gemma) have narrower terms.
