Google Launches Gemini 3.8 Flash and Cyber Variant

Google officially launched Gemini 3.8 Flash and the security-focused 3.8 Flash Cyber on September 2, announced by CEO Sundar Pichai, Google DeepMind, Google AI, GeminiApp and executive Logan Kilpatrick. This is the third Flash update in six weeks and the fourth Flash model in four months. 3.8 Flash is live in the Gemini app, Google AI Studio, the API and Antigravity, available to Pro and Ultra subscribers, and positioned as a workhorse model for long-horizon coding and autonomous agents.

Confirmed

• 3.8 Flash: billed as the smartest Flash yet, with significant gains over 3.7 Flash in software engineering, agentic tasks and multi-step reasoning; DeepSWE 1.1 score of 71% approaches Opus 5 at far lower cost (user-side assessment). Artificial Analysis measured a high-reasoning intelligence index of 59 (vs 56 for 3.7 Flash) and $0.58 per task, placing it on the price-performance Pareto frontier.
• Pricing and speed: $0.75 input / $0.75 output pricing unchanged — input $0.75 and output $3.75, matching 3.7 Flash's launch price. Per Reddit user NewVeterinarian5384's compilation of the official blog, output reaches 305 tokens/sec, nearly double second-place Muse Spark 1.2 (154 t/s) and far ahead of GPT-5.6.
• Capabilities: Google AI highlights complex agents and multi-step tasks spanning coding, video understanding and everyday assistance; effort controls retained, with a demo autonomously building a 3D game and self-correcting.
• 3.8 Flash Cyber: announced by Pichai, DeepMind and Google AI as Google's strongest cybersecurity model, featuring expert-level vulnerability detection, autonomous patching and large-scale patch generation; 2.6x improvement in Chrome patch correctness over the 3.5 generation and Pareto-frontier results on CWE-Bench, while keeping Flash-tier speed and pricing.

Why it matters

• Same-price performance and speed gains squeeze competitors' price-performance room: YouTube channel Prompt Engineering calls it Google's strongest agentic coding model, and blogger SabooShubham argues the rapid cadence particularly benefits AI agent workflows.
• Cyber brings frontier vulnerability discovery and autonomous patching to defensive security teams at Flash-level pricing, potentially reshaping security operations automation.
