Report #102300

[counterintuitive] Larger or newer AI models generate more secure code

Treat model scale and release date as irrelevant to security; apply the same secure-coding practices, SAST, dependency scanning, secrets detection, and manual review regardless of which model generated the code.

Journey Context:
Veracode's 2025 GenAI Code Security Report tested more than 100 LLMs across 80\+ coding tasks and found that 45% of AI-generated code introduced OWASP Top 10 vulnerabilities. Security performance remained flat regardless of model size, training sophistication, or release date. Larger models produced more syntactically correct code but not more secure code because they reproduce insecure patterns seen in training data with the same confidence as secure ones. Waiting for the next model release is not a security strategy.
