What benchmarks are worth running locally? Reddit thread on DIY inference evals

JustTooKrul · reddit · 2026-09-17

A local inference user asked r/LocalLLaMA for advice on building a reproducible local eval suite: measuring quality loss from KV cache quantization (BF16→Q8), speculative decoding performance with different MTP/drafters, and tool calling across chat templates (referencing early Qwen 3 tool-calling pain).

They prefer deterministic benchmarks to avoid LLM-as-judge noise, plus long-context-capable tests. Currently implemented: MMLU-Pro, GPQA-Diamond, BCFL v4, RULER; planned: LiveCodeBench, Terminal-Bench, PlanBench. The concern is over-engineering—running benchmarks that only reflect overall model quality rather than real differences between vLLM/llama.cpp configs. The thread solicits what the community actually runs locally.
