What machines can deploy Qwen locally?
For the small stack, start with Qwen 3.5 9B on a 32 GB machine. Ollama’s current quantized package is about 6.6 GB and advertises a 256K context window, leaving the rest of system memory for the context cache, runtime, and operating system.
The recommended small stack: Qwen 3.5 9B
Qwen 3.5 9B is a multimodal model that accepts text and images. Ollama’s default 9B package is about 6.6 GB with a 256K advertised context window. That combination makes it a much more realistic fit for a 32 GB desktop than the 27B-and-larger class.
32 GB RAM
Recommended for Qwen 3.5 9B. It leaves meaningful capacity beyond the 6.6 GB quantized weights for a large KV cache and normal system overhead.
64 GB RAM
The safer long-context workstation. Choose this when you expect 100K-token prompts frequently, keep development tools open, or want larger quantizations.
96–128 GB RAM
Useful for 27B-class models, multiple concurrent models, CPU-first deployments, or avoiding aggressive memory compromises.
Can 32 GB handle a 100K-token context?
Qwen 3.5 9B is the specific case where 32 GB is a reasonable recommendation for trying it. The model package is relatively small and advertises up to 256K context in Ollama. Still, context support is not the same as guaranteed memory fit: cache format, image inputs, runtime version, thinking output, and concurrent applications change the footprint.
Use 32 GB as the value-oriented target for a single-user 100K-token experiment. Use 64 GB when you need that context length reliably, want fewer tuning compromises, or plan to run other memory-heavy software at the same time.
Install with Ollama
Install Ollama, then run the 9B model explicitly:
ollama run qwen3.5:9bReview the exact download size and context limit before selecting a tag in the Qwen 3.5 library on Ollama.
Hardware priorities
- RAM capacity: 32 GB recommended for the Qwen 3.5 9B small stack; 64 GB for dependable long-context work.
- GPU VRAM: more layers on GPU generally means faster responses.
- Memory bandwidth: particularly important when weights spill into system RAM.
- Cooling and power: long generations can sustain CPU or GPU load.
- Upgrade paths: extra DIMM slots make inexpensive workstation platforms attractive.
