What problem does it solve? A model that serves cleanly can still answer benchmark questions wrong. This Skill measures how accurately a text model behind a MAX OpenAI-compatible endpoint answers standard datasets, separates serving failures from wrong answers, and writes reproducible per-task scores you can compare against a model card. ## Core Features & Use Cases - Standard benchmark evaluation: Runs GSM8K, MMLU, HellaSwag, ARC, AIME, GPQA, TruthfulQA, WinoGrande, and BABILong through lm-eval or direct-HTTP scorers against a served model. - Preflight and fast-fail checks: Verifies endpoint capabilities (chat completions, prompt logprobs via --enable-echo) before downloading datasets, and runs a small seed pass to catch broken endpoints or answer-extraction failures early. - Reproducible summaries and targets: Writes per-task and combined JSON summaries with effective configuration and dependency versions, and supports one-sided --target floors for pass/fail comparison against model-card scores. - Use Case: After importing a new model into MAX, serve it with --enable-echo and run gsm8k plus mmlu with targets from the model card to verify the deployment answers correctly before release. ## Quick Start Ask the agent to evaluate the model meta-llama/Llama-3.1-8B-Instruct on the gsm8k task against your local MAX endpoint and report the accuracy summary.
