Review: Qwen 2.5 72B excels at coding but fails logic benchmarks with severe hallucinations
Afinetheorem · x · 2026-08-17
- Key Takeaway: The local model Qwen 2.5 72B performs well on code benchmarks but makes significant trade-offs to maintain that performance.
- Specific Performance: In vision/logic benchmarks, it is one of the worst models tested, suffering from severe hallucinations compared to frontier closed models (like Claude).
- Comparison: Even the full-parameter Qwen 2.5 72B only matches the level of o4-mini or Sonnet 4.5. These quantized, RL-optimized coding models exhibit jagged capabilities in general tasks.
