Qwen3 14B
Plan for 12 GB of dedicated GPU memory at Q4_K_M and a 4,000-token context. 16 GB gives more headroom under the same settings.
General chat with a larger model. Memory fit is an estimate, not a speed or quality guarantee.

| Dedicated GPU memory | At 4,000 tokens | At 16,000 tokens | Example from these guides |
|---|---|---|---|
| 12 GB | Smallest listed tier that fits10.2 GB + 0.36 GB reserve | Fits the estimate11.2 GB + reserve | RTX 3060 12 GB |
| 16 GB | More headroom10.2 GB + 0.48 GB reserve | Fits the estimate11.2 GB + reserve | RTX 4060 Ti 16 GB |
The smallest tier fits the calculation; it is not a verified minimum. Cache precision and runtime buffers can change the fit. “More headroom” means at least 2 GB remains after the estimate and reserve.
Use the publisher’s Instruct / chat template in a current GGUF-capable runtime. The 12 GB tier can become tight when display use, buffers or context grow. CPU offloading needs adequate system RAM and changes performance; it is not included in these full-GPU estimates.
Compare quantisation and context
| File profile | Weight input¹ | GPU estimate at 4K | GPU estimate at 16K |
|---|---|---|---|
| Q4_K_M | 9.00 GB | 10.2 GB | 11.2 GB |
| Q5_K_M | 10.51 GB | 11.7 GB | 12.7 GB |
¹ Catalogue planning weights. These can differ from an exact downloaded file; runtime memory also includes cache and buffers.
Keep the exact file, runtime version, cache type and context limit consistent when comparing. Q5 uses more memory; compare its answers on your own tasks before accepting the trade-off.
Setup and common questions
How should I set up a first run?
Use Qwen/Qwen3-14B, the publisher’s GGUF file and the current Qwen3 chat template. Confirm GPU offload and check memory during generation before increasing context. Keep thinking mode fixed between runs.
Can I use longer context?
Qwen lists 32,768 native tokens and up to 131,072 with YaRN. The extended limit needs explicit runtime support and additional cache memory; it is not a promise of GPU fit.
What if it does not fit?
Reduce context, use a smaller file or offload some layers to system RAM. Compare Qwen3 8B if you want to keep the workload on the GPU. See context length.
How are these recommendations chosen?
We compare dedicated GPU memory tiers using the main Finder’s memory calculation at the stated quantisation and context. These tiers describe memory fit, not speed or output quality.
GPU memory includes weights, context cache and a 0.9 GB runtime allowance, plus a 3% reserve (0.15–1.5 GB). Cache format and runtime buffers can change the fit. See the calculation assumptions.
