Common questions
Llama 3.3 70B vs Qwen 2.5 72B: which is bigger?
Qwen 2.5 72B has more parameters (Llama 3.3 70B: 70 B; Qwen 2.5 72B: 72 B). More parameters usually means higher ceiling on capability and higher memory requirement, though MoE architectures decouple total parameters from per-token compute.
Llama 3.3 70B vs Qwen 2.5 72B: which is newer?
Llama 3.3 70B released 2024-12-06; Qwen 2.5 72B released 2024-09-19.
Llama 3.3 70B vs Qwen 2.5 72B: which needs less memory to serve?
Llama 3.3 70B needs less HBM. Weights-only footprint at FP16: Llama 3.3 70B 140 GB; Qwen 2.5 72B 144 GB. Half those numbers at INT8, quarter at INT4. Real serving adds 10-30% for KV cache.
Llama 3.3 70B vs Qwen 2.5 72B: which license is more permissive?
Llama 3.3 70B: Llama 3.3 Community License. Qwen 2.5 72B: Qwen License (72B only). 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. Check the model card for the exact clauses.
