GPT-5.5 System Card

Organizations that ignore the shift toward agentic workflows risk operational obsolescence as competitors adopt models capable of end-to-end task completion. Embracing these tools enables the automation of complex research and document creation, moving beyond simple chat interfaces. However, the reliance on autonomous agents introduces significant security vulnerabilities if biological or cybersecurity safeguards are bypassed. While the model excels at multi-tool orchestration, it remains dependent on the quality of initial instructions and the accuracy of its self-correction mechanisms.

GPT-5.5 introduces a shift from passive assistance to active task completion, requiring less user guidance and demonstrating improved tool-use efficiency. The model now performs iterative self-verification to ensure objectives are met before signaling task completion. OpenAI separated evaluations for GPT-5.5 and GPT-5.5 Pro to account for the risk profile introduced by parallel test-time compute. Despite these advancements, the model is still bound by the limitations of its offline training evaluations.
