GLM-5 vs GPT-5.4

Pick two tools from the same category to compare side-by-side.

	GLM-5 Zhipu AI's MIT-licensed 744B-parameter MoE model targeting complex systems engineering and agentic tasks.	GPT-5.4 OpenAI's more affordable frontier model for coding and professional work, sitting below GPT-5.5.
Category	model	model
Vendor type	open source	commercial
Pricing	free	usage
Strengths	+ MIT-licensed open weights + Designed specifically for agentic and tool-use workloads + Sparse attention architecture reduces long-context serving cost + 40B active parameters keep inference cost moderate for its class	+ Half the per-token price of GPT-5.5 while staying in the frontier coding/professional tier + 1M-token context window with up to 128K output tokens + mini variant targeted at subagent and computer-use workloads for high-volume agent fleets
Tradeoffs	− 744B total parameters still demand multi-GPU infrastructure to self-host − Smaller first-party API ecosystem than DeepSeek or Alibaba	− OpenAI directs complex reasoning and coding to GPT-5.5 instead − Older knowledge cutoff (Aug 31, 2025) than GPT-5.5
