GPT-5-Codex safety measures for agents
Mitigations for GPT-5-Codex include model-level and product-level safety features.
Utilize specialized safety training for harmful tasks and prompt injections, agent sandboxing, and configurable network access.
Potential for harmful tasks or prompt injections with agentic coding models.
These measures are implemented to ensure the safe operation of GPT-5-Codex in agentic coding scenarios.
Safety measures for GPT-5-Codex include model-level training against harmful tasks and prompt injections, and product-level features like agent sandboxing and configurable network access.
This layered approach addresses safety at both the model's core training and its deployment environment.
When not using GPT-5-Codex or when agentic capabilities are not a concern.
