Z.ai: GLM 5.3 Flash (batch)

GLM 5.3 Flash (batch) is a Z.ai model that accepts text, image, and video input and returns text. It offers a context window of 1,048,576 tokens and can produce up to 131,072 tokens in a single completion, so it can take in long documents or extended multimodal inputs in one request. It supports tool calling and a reasoning mode. The listing does not confirm structured output support or open-weight availability, so verify both with the vendor if your pipeline depends on them. At $0.05 per million input tokens and $0.18 per million output tokens, this model belongs on the shortlist for cost-sensitive, high-volume work, especially jobs involving large contexts or mixed media. Its blended benchmark score of 69.6 comes from a single independent benchmark, so its standing against other models is not well established. Teams should run their own evaluations before treating that number as a reliable guide to quality.
