Ollama adds Z.ai's GLM-5.3-Flash: 18B active params, 1M context, near Opus 4.8
ollama · x · 2026-08-28
Ollama's cloud now hosts Z.ai's GLM-5.3-Flash, the first natively multimodal model in the GLM-5 series. With 320B total and only 18B active parameters, it reportedly beats GLM-5.2 at one-tenth the cost while approaching Claude Opus 4.8 on coding and agentic benchmarks. Before release it was tested anonymously as ox-alpha, becoming the most popular model of the week. Features a 1M context window, vision, tools, and thinking; plug-and-play with Claude Code, OpenCode and other agent apps.
