Google launches Gemini 3.8 Flash and Flash Cyber

On September 2, Google DeepMind officially released two new Gemini models: the general-purpose Gemini 3.8 Flash and the cybersecurity-focused Gemini 3.8 Flash Cyber. The company says 3.8 Flash is the smartest Flash model to date, arriving just three weeks after 3.7 Flash.

Confirmed

• According to the model card (as observed by @cedricchee), 3.8 Flash shows significant gains over 3.7 Flash in software engineering, agentic tasks, and multi-step reasoning, with improvements centered on software engineering and agentic knowledge workflows
• DeepMind researcher koraykv relayed that 3.8 Flash can beat most larger frontier models on complex engineering problems at very low cost
• 3.8 Flash Cyber is positioned as the strongest cybersecurity model, focused on finding and fixing vulnerabilities, and sits on the Pareto frontier of vulnerability-patching tests on CWE-Bench
• DeepMind has published the Gemini 3.8 Flash model card

Why it matters

• 3.8 Flash continues the momentum of 3.7 Flash, pushing frontier-level performance with low-cost, scalable deployment and further squeezing the space for high-cost models
• The Cyber variant is another signal of the Gemini series specializing toward vertical security scenarios, with vulnerability discovery and remediation capabilities aimed directly at enterprise security and code auditing needs
