Can I run Huihui-GLM-4.7-Flash-abliterated-57B on a Radeon RX 6500 XT?

Q: Can I run Huihui-GLM-4.7-Flash-abliterated-57B on a Radeon RX 6500 XT?

No. No published quantization of Huihui-GLM-4.7-Flash-abliterated-57B fits a Radeon RX 6500 XT at any context with q4_0 KV cache.

Not at these settings. No indexed quantization of Huihui-GLM-4.7-Flash-abliterated-57B fits Radeon RX 6500 XT at any context we compute, with q4_0 KV. The smallest shipped quantization is 10.79 GiB in weights alone, against 3.72 GiB usable. CPU offload can still run it, slowly.

●From the file◐Predictedwhat these mean

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 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.
