What is GLM-4.5

GLM-4.5 is an open source SOTA model from Smart Spectrum, designed for intelligent body applications, incorporating reasoning, code generation and intelligent body capabilities. The model is based on the Mixed Expert (MoE) architecture and consists of two versions, GLM-4.5 with 355 billion parameters and GLM-4.5-Air with 106 billion parameters and 32 billion and 12 billion activation parameters, respectively. The model performs well in reasoning, code generation, and other tasks, supports multimodal inputs and outputs, and provides "thinking mode" and "non-thinking mode" to adapt to complex tasks and immediate response needs. The model has high parameter efficiency, low API call cost, fast generation speed, and is suitable for full-stack development, programming assistance, content creation and other scenarios, making it the best open-source model at present.

Technical specifications of GLM-4.5

  • Overall performance SOTA: Among 12 representative evaluation benchmarks, GLM-4.5 achieved the third place in global models, the first place in domestic models and the first place in open source models. The evaluation benchmarks include MMLU Pro, AIME 24, MATH 500, SciCode, GPQA, HLE, LiveCodeBench, SWE-Bench Verified, Terminal-Bench, TAU-Bench, BFCL v3, and BrowseComp, which fully proves that GLM-4.5 can be used for multiple inference, code generation and intelligent body application. 4.5's excellent performance in multiple scenarios such as inference, code generation and smart body applications.
  • Higher parameter efficiency: GLM-4.5 has only 1/2 the number of parameters of DeepSeek-R1 and 1/3 the number of Kimi-K2, and performs much better in many standard benchmarks. On the SWE-bench Verified list, which measures the capability of the model code, the GLM-4.5 series is located at the performance/parameter ratio Pareto frontier, indicating that the GLM-4.5 series achieves the best performance at the same scale.
  • Low cost, high speedGLM-4.5 series achieves breakthroughs in cost and efficiency while optimizing performance: the API call price is as low as $0.8/million tokens for input and $2/million tokens for output, which is far lower than mainstream model pricing. The high speed version can generate up to 100tokens/sec, which supports low latency and high concurrency deployment, taking into account the cost-effectiveness and interactive experience.
