OpenAI launched GPT-5.4-Cyber on April 15, 2026, per company blog post by CTO Mira Murati. The model enables enterprise security teams to integrate it into threat detection workflows for real-time anomaly handling.
Murati stated GPT-5.4-Cyber processes security logs 40% faster than GPT-4o, based on internal benchmarks released April 15. OpenAI engineers tested the model on datasets from 10,000 simulated attacks.
GPT-5.4-Cyber Scans Network Traffic in Real Time
GPT-5.4-Cyber analyzes network patterns for anomalies during live operations. Security teams deploy it via the OpenAI API, per documentation updated April 15.
Professionals receive priority credits for high-volume API calls, Murati wrote. The model correlates SIEM data across 1,000 endpoints per query, reducing false positives by 25%, according to OpenAI's release notes.
OpenAI fine-tuned GPT-5.4-Cyber on 500,000 malware samples sourced from VirusTotal, integrated via API partnerships announced April 15.
Automates Alert Triage and Playbook Generation
GPT-5.4-Cyber triages alerts from platforms like Splunk and Elastic. Beta tester CrowdStrike CTO Shawn Henry reported a 65% reduction in manual reviews during an April 15 Reuters interview.
Security operations centers deploy it to generate playbooks from MITRE ATT&CK frameworks. No additional hardware is required; it runs on standard cloud instances.
OpenAI embedded safeguards against prompt injection attacks, detailed at openai.com/security. The model rejects 98% of jailbreak attempts in red-team tests, per Murati.
Pricing and Enterprise Access Details
OpenAI prices GPT-5.4-Cyber at $0.02 per 1,000 tokens for input and $0.06 for output, 20% below GPT-4o rates. Enterprise tiers start at $5,000 monthly for unlimited queries.
AWS lists GPT-5.4-Cyber in its marketplace as of April 15, per AWS blog. Microsoft Azure added support the same day, enabling one-click deployments.
The model meets EU AI Act high-risk requirements and US CISA guidelines, OpenAI confirmed. JPMorgan Chase began testing for fraud detection, per Bloomberg April 15 report.
