Zhipu AI Releases GLM-5.1: Massive 744 Billion Parameter Model That Beats GPT-5.4

Zhipu AI has open-sourced GLM-5.1, a colossal AI model with 744 billion parameters that reportedly outperforms OpenAI's GPT-5.4 on coding benchmarks.

The model was launched on April 8, 2026, representing a significant leap in open-source AI. GLM-5.1 is built using a mixture-of-experts (MoE) architecture that makes it extremely powerful for code generation and technical problem-solving.

What Makes GLM-5.1 Revolutionary?

With its 744 billion parameters, GLM-5.1 is among the largest open-source models ever released. It uses MoE architecture to activate only relevant parts of the network for each task, making it both powerful and efficient.

Key features:

• 744 billion parameters in mixture-of-experts design
• Superior performance on coding benchmarks vs GPT-5.4
• Fully open-source and available to everyone
• Optimized for programming and technical tasks

Performance Against Established Models

Zhipu AI's internal testing shows that GLM-5.1 consistently outperforms OpenAI's GPT-5.4 on standardized coding benchmarks. This is remarkable considering GLM-5.1 is completely free and open-source.

The comparison includes:

• Code generation and debugging
• Algorithmic problem-solving
• Multi-language programming
• Technical documentation

Strategic Significance

The launch marks a new phase in the global AI competition where Chinese companies are not only competing technologically but also offering powerful models free to the developer community.

This could shift the balance in the AI market, where open-source alternatives are becoming increasingly competitive against commercial solutions from Western tech giants.

GLM-5.1 is available for download and can be implemented by anyone wanting advanced AI technology without licensing costs.
