Gemini 3.5 Flash Cyber - Google's dedicated cybersecurity model
Gemini 3.5 Flash Cyber is a dedicated cybersecurity model fine-tuned by Google based on Gemini 3.5 Flash. It is used in conjunction with the CodeMender code security agent and specializes in vulnerability discovery and remediation.
What is Gemini 3.5 Flash Cyber?
Gemini 3.5 Flash Cyber is a dedicated cybersecurity model fine-tuned by Google based on Gemini 3.5 Flash. It is used in conjunction with the CodeMender code security agent, specializing in vulnerability discovery and remediation. The model employs a multi-agent collaborative architecture, with multiple agents working together to generate a unified security report. It achieves state-of-the-art performance on the CyberGym benchmark, and its cost per token is lower than larger models. Due to the risks associated with dual-use, it is currently only available to governments and trusted partners.
Main functions of Gemini 3.5 Flash Cyber
-
Vulnerability ScanningThe model can automatically scan code repositories and identify potential security vulnerabilities and risks.
-
Vulnerability FixFor the vulnerabilities discovered, the model generates remediation suggestions and patch code, and verifies their effectiveness.
-
Safety ReportThrough a multi-agent collaborative architecture, the analysis results are aggregated and a unified structured security report is output.
-
Batch AuditIt processes massive amounts of code in a low-cost, high-throughput manner, and supports enterprise-level security scanning and CI/CD pipeline integration.
-
Risk ratingPrioritize and assess the impact of detected vulnerabilities to help defenders allocate remediation resources appropriately.
Technical Principles of Gemini 3.5 Flash Cyber
- Model BasicsBased on the Gemini 3.5 Flash architecture, we have made special fine-tuning for network security, inheriting its high token utilization and low latency characteristics, and trained it on network security corpora such as vulnerability databases, CVE reports, and security patches.
- Multi-agent collaboration architectureThe system enables multiple Flash Cyber agents to work collaboratively through the CodeMender platform. This includes detecting vulnerabilities by scanning code, verifying agent reproduction to eliminate false positives, patching agents and testing compatibility, and summarizing and integrating agents to output a unified security report.
- Efficiency optimization: Reduce token consumption by leveraging the efficient inference capabilities of the Flash series, shorten the security audit cycle through multi-agent parallel processing, and achieve a lower cost per token than models with larger parameters.
- Safe alignmentDuring the training phase, security constraints are embedded to prevent the model from being induced to generate offensive code. The output layer filtering mechanism ensures that only defensive remediation suggestions are returned, while the risk of dual-use is managed through limited access pilots.
How to use Gemini 3.5 Flash Cyber
The model is not open to the public; limited access pilot programs are open only to government agencies and vetted trusted partners.
The core advantages of Gemini 3.5 Flash Cyber
- Cost leadershipBased on the Flash architecture, it achieves efficient inference with a cost per token that is significantly lower than competing models with larger parameter scales, making it suitable for enterprise-level large-scale security audits.
- Multi-agent collaborationCodeMender has four built-in agents for detection, verification, remediation, and aggregation, which work together to automate the entire closed loop from vulnerability discovery to report generation, reducing manual intervention.
- Cutting-edge performanceIt achieved top-tier industry performance in CyberGym benchmark tests, placing it in the same competitive range as dedicated security agents from Anthropic and OpenAI.
- Rapid ResponseInheriting the low-latency characteristics of the Flash series, it generates vulnerability scanning and remediation suggestions quickly, shortening the security response time window.
- Risk is controllableAdopting a limited access pilot strategy, opening access only to governments and trusted partners, while providing defensive capabilities and strictly preventing dual-use abuse.
