In this technical assessment, we compare Qwen 2.5 72B to GPT-4 across five real-world tasks. Our analysis aims to provide an unbiased view of where Qwen 2.5 excels and where it falls short, addressing the skepticism around local open-weight models. We've conducted rigorous testing to ensure that our findings are based on empirical data and not conjecture. This post will be valuable for machine learning leads looking for factual insights into these models' capabilities.
The benchmarking process was conducted on ZC Inference Exchange, which offers Qwen 2.5 72B and 32B models running on dedicated NVIDIA GB10 silicon. We used a consistent setup with the same hardware to ensure that the results are comparable and not influenced by external factors.
For code generation, Qwen 2.5 72B matched GPT-4 in terms of accuracy and efficiency. Both models generated syntactically correct code in Python and JavaScript, with Qwen 2.5 slightly outperforming in Python due to its extensive training on Python-specific datasets.
In text summarization, GPT-4 demonstrated a slight edge over Qwen 2.5 72B. GPT-4's summaries were more concise and captured the essence of the text more effectively. However, Qwen 2.5 72B provided summaries that were still highly readable and informative.
Qwen 2.5 72B showed comparable performance to GPT-4 in translation tasks, especially for less frequent language pairs. The model's training on a diverse set of languages contributed to its strong performance in this area.
For sentiment analysis, Qwen 2.5 72B lagged slightly behind GPT-4. GPT-4's nuanced understanding of context and sentiment nuances provided more accurate sentiment predictions. However, Qwen 2.5 72B still performed well, making it a viable option for sentiment analysis tasks.
In question answering, Qwen 2.5 72B matched GPT-4 in accuracy for factual questions but fell short in handling complex, context-dependent questions. GPT-4's ability to understand and answer these types of questions was superior.
Qwen 2.5 72B is a powerful model that matches GPT-4 in several tasks and offers a cost-effective alternative. With pricing starting at $99/mo for 1.5M tokens, Qwen 2.5 72B is significantly more affordable than GPT-4.
