GLM-4.6 – Zhipu’s Latest Flagship Model and Its Most Powerful Coding Model

What is GLM-4.6？

GLM-4.6 is Zhipu’s next-generation foundation model, with a total parameter count of 355B and 32B active parameters. It represents a comprehensive upgrade in real-world programming, long-context handling, reasoning, information retrieval, writing, and agent applications. Its coding ability rivals Claude Sonnet 4, context length has been extended to 200K, reasoning and search capabilities are significantly enhanced, multilingual translation has been improved, and it offers an excellent price-performance ratio. GLM-4.6 is optimized for Cambricon chips, enabling efficient inference deployment, and provides powerful AI support for developers and enterprises, driving broad adoption and innovation in AI technology. GLM-4.6 is now available on Zhipu’s MaaS platform, where subscribers can immediately experience its performance.

Key Features of GLM-4.6

• Programming Ability: Excels in both public benchmarks and real-world programming tasks, performing strongly in scenarios such as complex debugging and cross-tool orchestration, with efficient and accurate code generation and optimization.

• Context Handling: Extended from 128K to 200K, supporting ultra-long document reading, cross-file coding, and complex reasoning tasks.

• Reasoning Ability: Supports tool-augmented reasoning, achieving best-in-class performance among open-source models across multiple benchmarks with strong logical reasoning.

• Information Retrieval: Optimized for long-term, in-depth information exploration, adept at deep research and integrating external/internal sources.

• Writing Capability: Produces high-quality, stylistically diverse text with natural readability and role-play adaptability, more aligned with human preferences.

• Multilingual Translation: Further strengthened in cross-lingual tasks, delivering precise and fluent translations.

• Agent Applications: Natively supports diverse agent-based tasks across office work, development, writing, and creative scenarios—improving PPT usability, front-end code aesthetics, and layout.

Performance of GLM-4.6

• Comprehensive Benchmarks: Evaluated on seven authoritative benchmarks (AIME 25, LCB v6, HLE, SWE-Bench Verified, BrowseComp, Terminal-Bench, τ²-Bench). Results show GLM-4.6 performs at the top level across most leaderboards, on par with Claude Sonnet 4, ranking as the leading domestic model.

• Real-World Programming Evaluation: Tested in the Claude Code environment for real programming tasks, GLM-4.6 surpassed other Chinese models and outperformed even Claude Sonnet 4 in practical performance. It also consumed fewer tokens on average, saving over 30% token usage compared to GLM-4.5 on similar tasks.

Hardware Adaptation

• Cambricon Chips: Deployed with FP8+Int4 mixed quantization on domestic Cambricon chips, marking the first integrated FP8+Int4 model deployment on local chips—significantly reducing inference costs without accuracy loss.

• Moore Threads GPU: Deployed on the vLLM inference framework, running stably at native FP8 precision, demonstrating strong ecosystem compatibility and rapid support with MUSA architecture and full-function GPUs.
