Z.ai: GLM Flash Latest

GLM Flash Latest 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, with completions of up to 943,718 tokens, so long documents, extended transcripts, or multi-part media inputs can fit in a single request. It supports tool calling and a reasoning mode. Whether it supports structured output is not documented in the available data, and its open-weights status is likewise unlisted. The pricing is lopsided: input costs $0.0261 per million tokens and output costs $0.9 per million. That makes it worth shortlisting for input-heavy work such as summarizing or querying large files, video, or image sets where responses stay short; output-heavy generation erodes the advantage. It has no independent benchmark coverage yet, so its quality is unproven. Teams considering it should run their own evaluations against current alternatives before committing.
