How Does GLM-4.5 Surpass o3, Gemini 2.5 Pro, and Grok 4 with 90% Success in Agentic Benchmarks?

GLM-4.5 from Z.ai is emerging as a strong open-source contender in AI, excelling in tasks that demand reasoning, coding, and agentic skills. It claims a 90% success rate in agentic benchmarks, outpacing models like o3, Gemini 2.5 Pro, and Grok 4. This piece covers its key features, performance data, and why it stands out.

What is GLM-4.5 and Its Key Advantages?

GLM-4.5 serves as Z.ai's advanced large language model, designed for intelligent agent applications. With 355 billion parameters and only 32 billion active at once, it balances power and efficiency. It supports a huge 128,000-token context window, allowing it to handle long documents and complex conversations seamlessly.

  • Hybrid thinking mode for in-depth problem-solving
  • Non-thinking mode for quick responses
  • Native function calling for tool integration
  • Full open-source access on platforms like Hugging Face
  • A lighter version, GLM-4.5-Air, with 106 billion parameters for easier setups

This setup makes GLM-4.5 versatile for tasks from coding to research.

Inside GLM-4.5's Architecture

GLM-4.5 uses a Mixture-of-Experts design, activating only needed parameters per query. This hybrid system switches between deep reasoning for tough problems and fast answers for simple ones. Here's a quick comparison with competitors:

Feature GLM-4.5 GLM-4.5-Air DeepSeek R1 Grok 4
Total Parameters 355B 106B 236B ~320B
Active Parameters 32B 12B 122B N/A
Context Window 128,000 tokens 128,000 tokens 64,000 tokens 256,000 tokens
Architecture Mixture of Experts MoE MoE Proprietary
Open Source Yes (MIT) Yes Yes No

This architecture boosts efficiency, making it ideal for practical applications.

Benchmark Performance

In tests across 12 global benchmarks, GLM-4.5 ranks third overall, beating DeepSeek and others in key areas. It shines in agentic tasks with a 90.6% success rate and coding scenarios.

Benchmark GLM-4.5 DeepSeek R1 Grok 4 Gemini 2.5 Pro Claude 4 Opus
Coding: LIVECode 72.9 77.0 81.9 80.1 63.6
Reasoning: MMLU 84.6 84.9 86.6 86.2 87.3
Math: MATH 500 98.2 98.3 99.0 96.7 98.2
Tool Use (Agentic) 90.6% 89.1% 92.5% 86% 89.5%

These results show GLM-4.5's strength in real-world coding and agent tasks, making it a top pick for developers.

Cost and Accessibility

GLM-4.5 keeps costs low, with pricing at $0.11 for input and $0.28 for output per million tokens. Compare that:

Model Input (USD/million) Output (USD/million)
GLM-4.5 $0.11 $0.28
DeepSeek R1 $0.14 $2.19
GPT-4 API $10.00 $30.00

It runs on just eight Nvidia H20 GPUs, easing entry for startups and individuals.

Agentic Capabilities and Use Cases

Built for autonomous agents, GLM-4.5 handles function calling, multi-step planning, and debugging. Real applications include:

  • Creating coding assistants
  • Analyzing documents like contracts
  • Supporting game development
  • Running scientific simulations
  • Integrating into enterprise tools

Experts praise its reliability, with Z.ai's CEO noting it sets new standards for open and affordable AI.

Why GLM-4.5 Matters in AI Development

As an open-source model under MIT license, GLM-4.5 promotes global access and community involvement. Unlike closed models, it allows full control and local deployment, fostering innovation.

Aspect GLM-4.5 GPT-4o Grok 4
Open Source Yes (MIT) No No
Local Deploy Yes No No
Cost Ultra Low High High
Community Dev Encouraged No No
Enterprise Control Full Limited Limited

This approach highlights China's growing role in AI and supports widespread adoption.
