Frequently asked questions about qwen3.8-flash-next
- How much VRAM do I need to run qwen3.8-flash-next?
- At 4K context, the smallest published build of qwen3.8-flash-next (Q4_K_M) needs roughly 159.1 GB of GPU memory once weights, KV cache, compute buffers and runtime overhead are counted. Bigger quantizations and longer context windows need more. It can also run partly or entirely on the CPU using system RAM, more slowly.
- Can I run qwen3.8-flash-next without a dedicated GPU?
- Yes, but slowly. Without a GPU the model runs on the CPU using system RAM, which usually means a few tokens per second rather than dozens. You would need at least 159.1 GB of free RAM for the smallest build.
- How big is the qwen3.8-flash-next download?
- The smallest published build is 111.8 GB. There are 2 builds in total, the largest being 176.1 GB. Leave some extra free disk space beyond the download itself.
- How do I run qwen3.8-flash-next locally?
- Install Ollama, then run "ollama run qwen3.8-flash-next:125b-a6b-q4_K_M" in a terminal. The weights download on first use and an interactive session opens.
