Putting models to the secure coding test: Plan vs default mode
Datadog Security Labs tests whether 'plan mode' in frontier LLMs produces measurably more secure code — practical data for organisations setting governance policies around AI coding assistants.
Summary written by editorial AI · Source link below
We tested Sonnet 5, Composer 2.5, and GPT 5.5 in plan mode and default mode to see whether plan mode produces measurably more secure code.
Editorial Analysis
As AI coding assistants become standard developer tools, empirical data on which modes produce fewer vulnerabilities is essential for setting safe-usage policies.
Incorporate secure-coding mode evaluations into your AI coding-assistant governance policy before broad developer rollout.
