Can the Framework Desktop 128GB run DeepSeek V4 Flash?
Data updated . Last reviewed the same day, when this catalog snapshot was written.
Usable memory on this 128 GB unified-memory config is 96.0 GB (75% of the sticker figure). A result under 2 GB of headroom is labeled tight.
Quant ladder
| Quant | Estimate | Headroom | Est. tok/s | Verdict |
|---|---|---|---|---|
| Q4 | 175 GB | -78.6 GB | 39.4 tok/s | No |
| Q8 | 4.5 GB | 91.5 GB | 1505 tok/s | Yes |
| FP16 | 698 GB | -602.3 GB | 9.85 tok/s | No |
- Formula estimate: parameter count × bytes per weight × 1.20. No GGUF file size is stored for this quant.
- GGUF file size plus an FP16 KV-cache estimate at 8,192 tokens. The cache counts only the layers and heads named in the method on the About page.
- Tokens/sec is a bandwidth roofline: GB/s divided by active weight GB. It is not a measured generation speed.
KV cache at 8K and 32K
FP16 KV-cache estimate: 0.7 GB at 8,192 tokens and 2.9 GB at 32,768 tokens. GQA counts two tensors (K and V) for the stored KV heads and head dimension. config.json also sets a sliding window of 128 tokens. The figures above assume every counted layer stores the full context, so they can overstate cache on sliding layers.
Offload
The Q4 estimate is 78.6 GB over usable unified memory. There is no separate GPU to spill from.
Ollama
No command. This catalog does not store a GGUF repo whose base model is deepseek-ai/DeepSeek-V4-Flash, so it does not invent an Ollama tag.
