Reporting from 2 sources: ASCII.jp, GIGAZINE.
Google released Gemini 3.8 Flash and Gemini 3.8 Flash Cyber on September 2, 2026. The Flash model improves multi-step reasoning for software development and AI agents, while the Cyber model handles vulnerability discovery and fixing. API prices stay flat until January 1, 2027, when they double.
Google's third Flash update in six weeks arrived on September 2 with Gemini 3.8 Flash, a model built around an agent loop that checks results, calls external tools, and repeats processing on complex tasks. The company says the model runs more reasoning steps than its predecessor on software development and specialized work, though higher reasoning levels consume more tokens.
Benchmarks in the announcement put Gemini 3.8 Flash at 73.7 percent on DeepSWE v1.1, up from Gemini 3.7 Flash's 65.3 percent, and 54.9 percent on HLE-Verified. Google states the model performs close to some higher-priced cutting-edge models.
The companion Gemini 3.8 Flash Cyber scored 86.2 percent on CyberGym and 47.2 percent on CWE-Bench for vulnerability fixing. Google says it prioritized fixing over attack capabilities and has begun using the Cyber model internally.
