Mistral Vibe adds smart approve mode, GLM 5.3 model, subagent management
Summary
Mistral has introduced three new features to its coding agent, Vibe: smart approve mode, the GLM 5.3 model, and enhanced subagent management. The GLM 5.3 model, which replaces GLM 5.2, is now available on paid plans and can handle up to 1 million tokens of context, making it suitable for managing larger codebases during complex tasks. The smart approve mode improves command approval by allowing Vibe to automatically run routine commands while requiring user confirmation for riskier actions. Additionally, the new management view enables users to operate subagents efficiently without leaving the main conversation. Mistral is focusing Vibe specifically on coding and work tasks, moving away from its prior status as a general-purpose chatbot.
