Recommended Settings for the MTP Version

For the MTP version, the recommended configuration is KV cache q5_1 and draft cache q8_0. This setup provides the largest possible context window for the model, with equal or even better speed when the context is heavily loaded.

Note: The MTP version works on its own. Run it without a DFlash or DSpark draft model at the same time.

ℹ️ About Paretrix Quantization Suite

Paretrix is an empirical, activation-aware quantization suite for GGUF language models and speculative decoding modules.

Pareto + Matrix → Paretrix. Each tier is priced so that no better trade exists at that compression. The suite measures real activation sensitivity (ΔKLD/MiB) per tensor class through llama-imatrix, learns rate tables from cross-architecture campaigns (THE MATRIX), and allocates bitwidths under exact budget targets: flat recipes where uniformity wins, rate-calibrated knapsack where heterogeneity pays.

Standard uniform quantization applies one bitwidth family across the whole network. Paretrix reads the model's own activation field (which classes are expensive to cut, which are nearly free, and where depth matters), then spends the budget where measurements show the greatest return.
