China's Zhipu Unveils GLM-4.5: A 355 Billion Parameter AI Model Challenging Global Leaders
July 28, 2025
Zhipu, a Chinese AI startup, is set to launch its most ambitious open-source AI model, GLM-4.5, aimed at competing with global leaders like OpenAI.
The GLM-4.5 model boasts a Mixture-of-Experts architecture with a staggering 355 billion parameters, although it activates only a 32-billion-parameter subset for efficiency.
Innovative features of GLM-4.5 include Grouped-Query Attention and a stability-focused training process, enhancing its capabilities for advanced reasoning and coding tasks.
Additionally, GLM-4.5 incorporates Multi-Token Prediction technology, significantly boosting inference speed and making it suitable for diverse applications.
The model is competitively priced at 11 cents per million input tokens and 28 cents per million output tokens, undercutting its predecessor DeepSeek's rates.
DeepSeek, which launched earlier this year, demonstrated that effective AI can be developed with a modest budget, having reported training costs of less than $6 million.
Zhipu's pricing strategy and model performance come amid geopolitical tensions that affect Chinese tech firms, particularly regarding access to critical hardware.
Despite its advancements, Z.ai faces challenges as it remains on the U.S. entity list, limiting American partnerships and collaborations.
Concerns about data privacy and censorship may hinder the adoption of GLM-4.5 in Western markets, echoing issues faced by other Chinese AI models.
China's government is prioritizing AI development as part of its national security strategy, fostering an independent ecosystem to enhance self-reliance.
The open-source nature of GLM-4.5 allows for unrestricted commercial use, contrasting with the trend of closed-source competitors, and may attract developers seeking accessible AI solutions.
As competition heats up, U.S. companies may need to reassess their strategies to keep pace with the evolving AI landscape driven by affordability and innovation.
