Qwen: Qwen3.5-Flash

Qwen: Qwen3.5-Flash, created on Feb 25, 2026, demonstrates exceptional speed, consistently ranking among the fastest models, and offers highly competitive pricing. Its reliability is strong, with an 88% success rate across benchmarks. In terms of performance, the model shows particular strength in acknowledging uncertainty, achieving 97.1% accuracy in Hallucinations (Baseline) tests, and in Email Classification, where it reached 97.4% accuracy. Instruction Following also yielded a respectable 63.6% accuracy. However, the model exhibits significant weaknesses in more complex cognitive domains, scoring 0.0% accuracy across Coding, General Knowledge, Reasoning, Ethics, and Mathematics benchmarks. This suggests a strong capability for specific, well-defined tasks and efficient processing, but a current limitation in handling open-ended, knowledge-intensive, or complex problem-solving scenarios. Its hybrid architecture and linear attention mechanism appear to contribute to its high inference efficiency.
