GLM 4.5 Air

GLM 4.5 Air is Z.ai's lightweight variant of GLM 4.5 with a 131K-token context window, designed for faster inference at a reduced capability tier.

Strengths

Provides lower-latency execution compared to the full GLM 4.5 model while retaining a substantial context window for processing extended inputs.

Best for

Applications where inference speed and efficiency matter more than peak reasoning capability, such as high-throughput chatbots, content summarization, and real-time text generation.

Limitations

Trades reasoning depth and accuracy for speed, making it less suitable for complex problem-solving, nuanced analysis, or tasks requiring state-of-the-art performance compared to the full GLM 4.5 or newer models like GLM 4.6.
