Local LLM Tuning Registry

A hosted registry + local CLI that benchmarks and recommends task-specific decoding/engine/quant presets for popular local models (e.g., Qwen3.5 GGUF on llama.cpp). It automatically runs standardized micro-benchmarks (latency, token cost, verbosity, repetition, instruction-following) on the user’s hardware and then applies proven community presets with reproducible results and version pinning.

Local LLM Tuning Registry

A hosted registry + local CLI that benchmarks and recommends task-specific decoding/engine/quant presets for popular local models (e.g., Qwen3.5 GGUF on llama.cpp). It automatically runs standardized micro-benchmarks (latency, token cost, verbosity, repetition, instruction-following) on the user’s hardware and then applies proven community presets with reproducible results and version pinning.

Target customer

Power users and small teams running local LLMs (developers, researchers, privacy-sensitive orgs) who need reliable performance and predictable behavior on their own GPUs/CPUs.

Problem-solution fit

Users are explicitly crowdsourcing "best parameters" because current guidance is scattered, hardware-dependent, and quickly outdated as inference engines and quants change. This product turns parameter hunting into a repeatable workflow: measure the user’s rig, run a short calibration suite, pick a target behavior (e.g., less overthinking), and output a pinned config (engine version + quant + decoding params) that can be shared and reused.
