GLM-5.2

Architectural Overview & Capability Profile

GLM-5.2 is developed by Zhipu AI as an advanced foundation model engineered for production enterprise applications, reasoning workflows, and autonomous problem-solving. On the comprehensive RankLLMs composite evaluation index, GLM-5.2 registers an overall benchmark rating of 48.2 / 100.

Operating under a Open Weights license structure, GLM-5.2 is distributed as an open-weights architecture capable of local deployment, private VPC inference, and custom fine-tuning.

Benchmark Performance & Real-World Utility

In standardized laboratory and real-world evaluation suites, GLM-5.2 demonstrates calibrated proficiency across key performance vectors:

• SWE-bench Verified Software Engineering (46.2%): Measures multi-file GitHub issue resolution. The model demonstrates practical capability in localizing source code bugs, synthesizing functional patches, and passing rigorous integration test matrices. For evaluation methodology, consult our SWE-bench Pro guide.

• GPQA Diamond Scientific Reasoning (54.7%): Assesses graduate-level domain problem solving across physics, chemistry, and biology, minimizing hallucinations in multi-step deductive arguments. See our Humanity’s Last Exam benchmark analysis.

• MATH-500 Competition Mathematics (54.7%): Evaluates formal mathematical problem solving and symbolic derivation, providing foundational logic for algorithmic computing.

• Terminal-Bench Execution (81%): Reflects proficiency in interactive command-line environments, shell tool use, and automated DevOps scripting.

• Code Arena Preference Rating (1508 Elo): Validates human developer satisfaction in blind side-by-side coding evaluations against contemporary alternatives.

Inference Latency & Cost Architecture

• Token Context Window: 1.0M tokens, allowing large documents, multi-file codebases, and long conversation memories to be processed in a single context window.
• Inference Speed: Reference throughput clocks at approximately 126 tokens/second, enabling responsive streaming in developer tools and interactive interfaces.
• Commercial Pricing: Zero per-token inference fee when self-hosted on owned GPU infrastructure (e.g. vLLM or Ollama), with marginal costs limited strictly to hardware compute.
