GLM-4.5 Air

GLM-4.5 Air is a lightweight text model developed by Zhipu as part of their GLM model family. Positioned as an efficient option within the GLM lineup, this model prioritizes speed and responsiveness for applications requiring quick text generation and processing. The model operates with a 128,000 token context window and supports tool calling functionality. Performance benchmarks show an output speed of 82.55 tokens per second with a time to first token of 644 milliseconds. GLM-4.5 Air focuses exclusively on text-based interactions through chat completion capabilities, without multimodal support for images or other input types. As a lightweight model, GLM-4.5 Air targets use cases where response speed and efficiency are prioritized over maximum capability. It competes in the tier of models designed for high-throughput applications rather than complex reasoning tasks that would typically require larger, more capable models.
