Comprehensive side-by-side LLM comparison
GPT-5 Pro supports multimodal inputs. Both models have their strengths depending on your specific coding needs.
OpenAI
GPT-5 Pro is an extended-reasoning variant from the GPT-5 family that applies more compute per response for deeper, more thorough answers on complex problems. It features the same 400K token context window and multimodal capabilities as GPT-5, with additional reasoning depth suited to research-grade analysis, advanced coding, and tasks requiring comprehensive, accurate outputs.
Alibaba / Qwen
Qwen2.5-14B-Instruct is a 14-billion-parameter language model from Alibaba released in September 2024 within the Qwen2.5 family, occupying the mid-tier of the series between efficiency-focused small models and the high-capability 72B flagship. Trained on 18 trillion tokens with emphasis on instruction alignment, code understanding, and multilingual reasoning, it offers a strong performance-to-compute ratio for developers who need more capability than 7B but cannot serve 32B or larger models. The model supports 128K context windows and structured output generation out of the box.
