Qwen3-Coder-30B-A3B-Instruct

Quality falls 9.5 points to 75.2 with near-doubled latency

Qwen3-Coder-30B-A3B-Instruct demonstrates significant performance degradation in this benchmark window. Overall quality dropped from 84.7 to 75.2, representing a 9.5 point decline that follows a previous 6.5 point decrease. This marks a concerning downward trend across consecutive windows. Latency deteriorated substantially, with p50 response times increasing 93% from 2009ms to 3886ms, nearly doubling the wait time for users. Category performance shows mixed results with sharp variations. Reasoning achieved a perfect 100 score, indicating strong logical capabilities. However, coding performance plummeted from 94 to 69, a 25 point drop that undermines the model's core positioning as a coding specialist. Factual accuracy scored 57, though this represents a new category without direct comparison. The previous window's multilingual and creative categories were not tested in the current period. The combination of declining quality metrics and significantly increased latency suggests potential infrastructure or model configuration issues. Users should expect notably slower responses and reduced coding performance compared to the previous benchmark period. The perfect reasoning score provides limited consolation given the substantial regression in the model's primary coding capabilities.
