Z.ai

GLM 5.3 Flash is Zhipu AI's next-generation high-speed, lightweight workhorse model. Engineered for high-throughput, low-latency agentic workflows, code generation, and multimodal tasks, it features native long context support with significantly enhanced inference throughput and extreme cost-efficiency. It excels in function calling, instruction following, logical reasoning, and multilingual understanding—ideal for enterprise API integrations, real-time interactive apps, and automated workflows.

GLM 5.3 is a large-scale reasoning model from Z.ai. It supports text input and output with a 1M-token context window, and is suited for long-horizon agent workflows, project-level software engineering, and complex multi-step automation. Reasoning efforts high and xhigh are supported; xhigh maps to max reasoning. It is particularly strong at coding and tool use across long-running tasks, able to maintain engineering context and follow standards consistently through a full development workflow, from requirements to multi-platform deployment, in a single task.
