DeepSeek-V3.2 vs Kimi-K2-Instruct
DeepSeek-V3.2 (685.4B parameters) and Kimi-K2-Instruct (1026.4B parameters) side by side: the memory each needs at every precision, what it costs to run on a live GPU, and the context window, KV cache and license where they are published. Numbers are computed from the models' published specs; this page does not rank quality.

VRAM is the weight size at each precision times a flat 1.2 overhead; see the methodology. The FP8 and INT4 rows need a quantized checkpoint or an engine that quantizes on load. The fit is the lowest-priced single GPU type that holds the model at that precision, or the lowest-priced multi-GPU set (up to 8) when none does. KV cache is for one sequence at 16-bit, computed from each model's config where the attention layout is known.
Which to pick
- DeepSeek-V3.2 needs less VRAM at its published precision (766 GB against 1147 GB), so it fits on a smaller GPU.
- DeepSeek-V3.2 lists the longer context window (163,840 tokens against 131,072).
These follow only from the facts in the table above. Whether either model does your task well is a separate question this page does not answer.
