Providers
Performance for glm-5.3
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).

More models from Z.AI
See all Z.AI models →GLM-5.3-FlashX is Z.AI’s high-speed inference model, designed for coding agents, real-time interactions, long-running agentic workflows, and applications that require fast token generation. It is heavily optimized at the inference infrastructure level for lower latency and higher execution efficiency, reaching generation speeds of up to 200 tokens per second. Compared with GLM-5.3-Flash, GLM-5.3-FlashX delivers up to 5× faster inference, with a stronger focus on low-latency and high-throughput workloads.
GLM-5.3-Flash is a high-efficiency multimodal model from Z.AI. It supports a context window of roughly 1 million tokens, along with text, image, and video inputs, and includes tool-calling capabilities. It is primarily designed for coding agents, complex reasoning, and long-horizon software engineering tasks. Built on the existing GLM technology stack, the model has been further post-trained and optimized to deliver strong performance while placing greater emphasis on inference efficiency, responsiveness, and cost.The model is offered at a limited-time 50% discount; users are welcome to try it.
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.
coding-glm-5.3-flash-free is the open and free version of coding-glm-5.3-flash. To ensure stable service performance, usage limits are in place: up to 5 requests per minute, 100 requests per day, and a daily token allowance of 1 million.
Coding GLM 5.3 Flash is a dedicated version of GLM 5.3 Flash built for AI coding and Coding Agent workflows. It is designed for code understanding, generation, editing, repository-level development, and automated software engineering tasks. With support for context windows of up to approximately 1 million tokens, it can handle large codebases and extended development sessions. The model also supports text, image, and video inputs, along with tool use, making it well suited for AI coding tools such as Claude Code, OpenCode, Cline, and other agentic development environments.
