DeepSeek V4 Flash

290.94 billion parameters in total, but only 20.36 billion are read for each token. That split is the whole point of the design: it costs the memory of a large model and the speed of a small one. Grouped-query attention keeps the cache small, so long contexts cost less here than on models of the same size.

Memory needed, by quantisation

At an 8k context window. Quality is our rough ranking of how much the compression costs you: anything at or above Q5 is hard to tell apart from the original in normal use.

Quantisation File size KV cache Total VRAM Quality What it costs you
Q8_0 287.89 GB 0.01 GB 288.76 GB 99% Lossless in practice. Use it when the memory is there.
Q6_K 222.19 GB 0.01 GB 223.05 GB 98% Very close to Q8 for two thirds of the size.
Q5_K_M 192.72 GB 0.01 GB 193.58 GB 96% The quality-first choice when Q6 will not fit.
Q4_K_M 163.59 GB 0.01 GB 164.45 GB 93% The default. Best size-to-quality ratio for local use.
IQ4_XS 143.95 GB 0.01 GB 144.81 GB 91% Importance-matrix 4-bit. Q4_K_S quality, smaller file.
Q3_K_M 132.43 GB 0.01 GB 133.29 GB 86% Degradation starts to show. A way to fit one size up.
IQ3_XXS 103.64 GB 0.01 GB 104.5 GB 79% Aggressive. Only worth it on very large models.

What a longer conversation costs

Same model at Q4_K_M, only the context window changes. This model uses sliding-window attention, so most layers stop growing past 128 tokens and the bill flattens out.
