Model Card
GLM-4.6V-Flash is a 9B-parameter vision-language model from Z.ai, the lightweight variant of the GLM-4.6V series. It supports a 128K-token context window and processes images, documents, charts, video frames, and text within a single request.
Its key differentiator is native multimodal function calling — images and screenshots can be passed directly as tool parameters, and visual tool outputs are consumed in the same reasoning chain. This bridges the gap between visual perception and executable action for multimodal agent workflows.
Best for latency-sensitive and cost-conscious applications that need vision-language capabilities: document understanding pipelines, UI-to-code conversion, visual QA, and multimodal agent loops. For maximum accuracy on complex visual reasoning, the full 106B GLM-4.6V model is available.

More AI Models From Z.AI
GLM 5.3 FlashX Legal
GLM 5.3 FlashX Legal is a closed-source variant of Z.ai's GLM-5.3-FlashX tuned for legal work, including legal research, contract review, and document drafting. It accepts text, image, and video input and returns text. It has a 1,048,576-token context window, which fits long contracts and case files in a single request, and up to 131,072 output tokens. It supports function calling. Pricing is $0.37 per million input tokens and $1.25 per million output tokens, the same as GLM-5.3-FlashX. On Vals AI's Legal Research Bench it scores 41.83, according to DataLearner. Z.ai has not published other benchmark results for it. It suits developers building contract analysis tools, legal research assistants, and drafting workflows that process long documents.
ChatGLM 5.3 Prime
GLM 5.3 Prime is a high-speed serving tier built on Z.ai's GLM-5.3, offered through third-party inference platforms rather than as an official Z.ai product listing. It runs the same 744-billion-parameter Mixture-of-Experts weights (40 billion active) as standard GLM-5.3, on infrastructure tuned for higher throughput. Vendor reports put its output throughput at 1.5 to 2 times the standard GLM-5.3 endpoint, at roughly double the per-token price, a pattern also seen with GLM-5.2's own "Fast" tier. No independent benchmark of the Prime endpoint exists, but since the weights are unchanged, it should inherit GLM-5.3's reported gains over GLM-5.2, including a 50% jump on Z.ai's Code Bench and gains on Terminal-Bench 3.0 and DeepSWE v1.1. It supports a 1,000,000-token context window, 128,000 max output tokens, three reasoning-effort levels, and function calling. Best suited for agent loops and coding assistants that chain many model calls and are latency-sensitive, where the throughput gain offsets cost.
ChatGLM 5.3 FlashX
GLM 5.3 FlashX is Z.ai's high-speed serving tier for GLM-5.3-Flash, using the same 320-billion-parameter Mixture-of-Experts weights (18 billion active) rather than a separate model. Z.ai runs it on faster inference infrastructure, reporting speeds up to 200 tokens per second. Because the weights are unchanged, it inherits GLM-5.3-Flash's benchmark results, including 63.4 on DeepSWE v1.1 and 48.8 on AutomationBench, both ahead of GLM-5.2. It keeps the same 1,000,000-token context window, 128,000-token max output, and function calling support. Pricing is $0.37 per million input tokens and $1.25 per million output tokens, about 2.5 times GLM-5.3-Flash's rate. It fits agent loops and coding assistants that call the model repeatedly and need lower per-call latency, where the added throughput offsets the higher per-token price.
