On a 48 GB GPU, 6 catalog models run fully on the GPU at an 8,192-token context. The most capable is Qwen3-Reranker-8B at BF16 (needs ~18.4 GiB). Pick a smaller model or a lower quant for more headroom.
Figures assume a 48 GB GPU paired with 32 GB of system RAM (a typical desktop), judged at an 8,192-token context. Speed depends on the specific card — this page ranks by fit, not speed.

Derived live from the fit engine + catalog at an 8,192-token context. "Fits in" is the modelled VRAM the sweet-spot quant needs (weights + KV cache + overhead). Speed depends on your specific card — check a GPU page or the calculator.
