Does Kimi-Linear-48B-A3B-Instruct fit in 8GB of VRAM?
Not at these settings. No indexed quantization of Kimi-Linear-48B-A3B-Instruct fits 8GB card at any context we compute, with q8_0 KV. The smallest shipped quantization is 9.77 GiB in weights alone, against 7.44 GiB usable. CPU offload can still run it, slowly.

Figures are GiB of total memory: weights plus KV cache plus compute buffer and backend overhead. Weights and KV are near-exact; the overhead term is modeled. Hover any cell for the breakdown.
Why there are no speeds on this page
A capacity is not a card. Whether a model fits depends only on memory, so every figure above holds for any 8GB accelerator. How fast it runs depends on memory bandwidth, which varies several-fold between cards of the same capacity — so putting a tokens-per-second number here would be inventing one. Pick a specific card from hardware and the speed column appears.
Why other calculators disagree
A parameters × bits ÷ 8 estimate ignores two things that dominate at long context. First, the weights themselves are not the nominal rate — quantizations are mixtures, so the real file is consistently larger than the label implies. Second, this model uses latent attention and allocates no V cache at all, so any formula reading num_key_value_heads overstates its cache by more than an order of magnitude.
