Providers
Performance for glm-5.2
Uptime is the percentage of requests that succeeded over the past 72 hours. AIHubMix continuously monitors every provider and automatically retries with the next-best provider when one returns an error or responds too slowly; Latency is total round-trip time (lower is better); Throughput is how fast the model writes (tokens per second, higher is better).

See all Z.AI models →GLM-5.3 is a coding and agentic reasoning model developed by Z.AI, designed for complex software engineering, long-horizon agent tasks, and vulnerability analysis. Built on GLM-5.2, it incorporates further post-training enhancements to improve coding capabilities, task execution, and token efficiency. The version currently available is an internal preview of GLM-5.3, with a TPM of approximately 1–2 million. As the model is still in testing, service stability is not guaranteed and it is not recommended for production use. We plan to add additional resources and capacity over the coming week to further improve availability and stability.
GLM-5.3 is Z.ai’s reasoning model for coding and agentic workflows, designed for complex software engineering, long-running agents, and vulnerability analysis. It uses the same base model as GLM-5.2, with scaled post-training improving coding, task execution, and token efficiency. This model is a limited-time preview version of GLM-5.3, intended for testing and evaluation only. Service stability is not guaranteed, and we do not recommend using it in production environments. We’re waiting for the official commercial API release and will integrate it as soon as official support becomes available.
GLM 5.2 is a large-scale reasoning model developed by Z Ai that supports text input and output. Featuring a 128,000-token context window, this model is designed to handle complex, data-heavy tasks. It is exceptionally well-suited for long-horizon agent workflows and project-level software engineering.
GLM-5.2-Fast-Preview is the high-speed version of Zhipu AI’s flagship model GLM-5.2, supporting a 1M ultra-long context. The model’s capabilities are aligned with the GLM-5.2 standard version, offering logical reasoning, long-text understanding, and code generation. Through inference acceleration optimizations, output TPS can reach 1.5–2× that of the GLM-5.2 standard version, significantly improving output speed. It is suitable for scenarios sensitive to output speed, such as real-time dialogue, multi-turn Agent calls, and streaming code generation.
coding glm 5.2 free (coding-glm-5.2-free) is a free coding-focused API route offered by AIHubMix, powered by Z.ai’s open-source flagship GLM-5.2 model. It is suitable for code generation, debugging, project-level development, tool use, and long-running agent tasks, with support for reasoning, function calling, and structured outputs. Compared with GLM-5.1, it offers stronger coding capabilities and a 1-million-token context window. Each account is limited to 5 requests per minute, 500 requests per day, and 1 million free tokens per day.
Currently, the special resources for this model are limited, but due to its popularity, the usage is too high, which may result in a large number of 429 errors. Resources have been coordinated, and improvements are expected in the coming weeks, so please stay tuned. In the meantime, it is recommended to use the regular-priced API model, which can ensure absolute stability. The model ID is glm-5.2.
