Ollama said GLM-5.3 and GLM-5.3 Flash (formerly Ox Alpha) are fully live on its cloud, hosted in the US and Europe with zero data retention. First-class launches include `ollama launch claude --model glm-5.3:cloud` and `ollama launch opencode --model glm-5.3-flash:cloud`, plus Claude Desktop and a raw API. That moves past a Flash-only preview: the full coding model now drops into the same agent harnesses developers already use, so teams can pick strength versus cost without leaving Ollama’s private endpoints.
Key Takeaways
- ✓GLM-5.3 and GLM-5.3 Flash are fully on Ollama Cloud with US/EU hosting and zero retention.
- ✓One-liners launch Claude Code and OpenCode; Claude Desktop and a generic API are supported too.
- ✓Full and Flash share one gateway, so agents can trade quality for cost without a new vendor stack.
