Qwen3.8 Max、Claude Opusに匹敵 — しかしハルシネーションが74%急増
AlibabaのQwen3.8 MaxはベンチマークでClaude Opus 4.8に匹敵するものの、ハルシネーション率が23%から40%へと急上昇しており、性能と信頼性の間の重大なトレードオフを示している。
alibaba released qwen3.8 max, achieving a score of 56 on the artificial analysis index to match claude opus 4.8, while also jumping 468 elo points on the gdpval-aa benchmark to 1,739. despite these gains, the model requires 64 steps per task and costs $1.14 per task—more than double its predecessor—while competitor kimi k3 scores higher for less money. furthermore, benchmarks show regressions: aa-omniscience fell 10 points, and the hallucination rate surged from 23% to 40%, meaning the model guesses more often rather than admitting ignorance. this indicates that while raw capability increased, the reliability necessary for enterprise deployment may have compromised.
