Zhipu's GLM-5.3-Flash adds native vision with day-0 SGLang support
Very excited to see native vision come to the @Zai_org GLM family, and impressed by the architecture work behind it!
AISummary
Z.ai released GLM-5.3-Flash, a 320B-A18B model, with day-0 support in SGLang, after appearing earlier as ox-alpha. The post calls it the first native multimodal model in the GLM-5 series and says it outperforms GLM-5.2 at one-tenth the cost, with stable 1M-token long-context performance.
AIWhy it matters
The post reports GLM-5.3-Flash's native multimodal design, its efficiency claims, and day-0 SGLang support, which bear on running it in practice.
