Benchmark

Also known as: Benchmark / AI評価指標 / ベンチマーク評価

A standardized set of tasks or datasets used to measure and compare AI model capabilities. MMLU, HumanEval, SWE-bench, and HLE are prominent examples covering reasoning, coding, and frontier difficulty.

Overview

Benchmarks are standardized tests for objective model comparison. Widely used examples: MMLU (knowledge and reasoning), HumanEval (code generation), SWE-bench (real GitHub bug fixes), MATH, and GPQA/HLE (doctoral-level science). As of 2026, frontier models exceed 80-90% on SWE-bench Verified.

Limitations

Benchmark contamination — models trained on test data — inflates scores. Benchmark performance also does not always predict real-world utility. Eval Harnesses that test models on task-specific custom evaluations are therefore important for production decision-making.

A comprehensive 2026 comparison of three leading SLMs: Qwen3.5-9B, GPT-4o-mini, and Claude 3.5 Haiku. Evaluates benchmarks (MMLU, HumanEval, math, vision), latency and throughput, cost analysis (API pricing vs local inference), Japanese language quality, multimodal capabilities, context windows, privacy, offline capability, and fine-tuning flexibility. Includes best-use-case recommendations for each model.
