Frequently asked questions
Which model runs best on RTX 4090 (24 GB): Llama 3.3 70B Instruct or Qwen 2.5 32B?
On a RTX 4090, Llama 3.3 70B Instruct does not fit in 24 GB—you need to offload part of it to the CPU, Qwen 2.5 32B in Q5_K_M (~30 tok/s). See the configurator to test your exact GPU.
Which uses the least VRAM?
In Q4_K_M, Qwen 2.5 32B fits in 19 GB versus 40 GB for its rival—a 21 GB gap, significant if you're targeting an RTX 3060 or a 4060 Ti 8 GB.
Can these models be used in commercial production?
Llama 3.3 70B Instruct is under Llama 3.3 Community — check the restrictions, especially the monthly user limits. Qwen 2.5 32B is under Apache 2.0 — also free to use. For SaaS, prefer Apache 2.0 or MIT.
Which one should you choose in 2026?
Depends on your primary constraint. Smaller / faster: Qwen 2.5 32B (32B). More capable: Llama 3.3 70B Instruct (70B). If you're unsure, run the configurator with your GPU and use case — it will decide based on both.
