Can I run Trinity-Large-TrueBase on a Radeon RX 6500 XT?
Not at these settings. No indexed quantization of Trinity-Large-TrueBase fits Radeon RX 6500 XT at any context we compute, with q4_0 KV. The smallest shipped quantization is 73.49 GiB in weights alone, against 3.72 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 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, most of this model's layers cache only a 4,096-token window rather than the full context.
