GPT-5.6 Sol Shows Why a Better Model Isn't a Uniformly Safer Model
Veracode Research’s latest secure-coding test finds GPT-5.6 Sol with a 15-point Python gain beneath modest aggregate movement, evidence that cyber capability and secure-code generation do not move in lockstep. OpenAI calls GPT-5.6 Sol its “strongest cybersecurity model yet.” Veracode’s extension test finds it scoring only two percentage points higher overall on secure-code generation than GPT-5.5, but it scores 15 points higher in Python.
