Comprehensive side-by-side LLM comparison
GPT-5 Pro supports multimodal inputs. Both models have their strengths depending on your specific coding needs.
Zhipu AI
GLM-4.5 Air is a lightweight variant from Zhipu AI's GLM-4 model family, designed for efficient deployments requiring lower inference cost while maintaining strong language understanding and generation capabilities. It targets cost-sensitive production workloads, API integrations, and applications where the full GLM-4.x series capacity exceeds requirements.
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.
