JEVBench · public 231

86.15 / 100

Micro accuracy across 48 Easy, 72 Original and 111 Hard-public decisions using the typed-decision serving bundle. Not an official leaderboard rank.

Benchmark efficiency: 67.601 published score points per GB of selected weights. This ratio is not an inference-speed measure; check the test settings to see whether the score covers the selected quantization.

Test settings: Publisher-run JEVBench public set: the selected Q4_K_M answered 199 of 231 items correctly using the bundled llama.cpp typed-decision server. The card reports 94.4% top-decision parity with the original weights on the same 231 items; the original/BF16 model answered 195 of 231.

Artifact-specific specialist result, rounded from 199/231. This is not an independent test, an official leaderboard rank, a general-chat score or a speed result. Plain chat is not the evaluation path: option-letter readout and per-type temperatures live in the bundled gguf_server.py, and llama.cpp b10454 or newer is required. The 1,274,396,256-byte GGUF contains the text decoder only; it excludes images, runtime memory and context memory. CC BY-NC 4.0; commercial use requires a separate StartLux license. The publisher recommends Q8_0 for higher decision fidelity even though this Q4 scored higher on the public set.

Memory and comparison limits

Context and version evidence: The repository and file name identify the selected model. Revision hashes are shown above when recorded. Tested context length, full hardware configuration and run date are not consistently recorded in this snapshot. Only settings explicitly stated in each benchmark record are known.

The 1.274 GB figure covers model weights in this file. It excludes the context cache, runtime, operating system and any separate multimodal files. It is not a measured RAM requirement or a token-generation speed.

Use the model ranking chart to compare one test at a time. Use the 8, 16 and 32 GB memory guide. Check hardware memory and bandwidth before choosing a model.
