Mistral Vibe is Mistral AI's open-source CLI coding agent powered by the Devstral 2 model (72.2% SWE-bench Verified). It explores, modifies, and executes code from the terminal with subagents, slash skills, and MCP support — claimed to be up to 7× more cost-efficient than Claude Sonnet at real-world tasks.
Trae is an AI coding platform with TraeCode, an AI IDE with unlimited autocomplete and SOLO mode, and TraeWork for running cloud tasks on web and desktop.
