GLM-5.1 and GLM-5.2, the latest open-source models from Z.ai for autonomous software engineering and repository-scale reasoning, are now available through DigitalOcean Inference Engine. GLM-5.1 is optimized for long-running agentic coding workflows and can sustain complex autonomous tasks for up to 8 hours, while GLM-5.2 introduces a 1M-token context window and dual reasoning modes for large-scale code analysis and refactoring. Both models support tool calling, structured output, and multilingual applications.
