Google says Gemini 3.5 Flash rivals 'large flagship models' for coding and agentic tasks - Engadget
"3.5 Flash delivers frontier-level intelligence at exceptional speed - proving you no longer have to trade quality for latency. Announced at Google I/O 2026, this will be Google's default AI model (not to be confused with Flash-Lite), designed to deliver better speed than the current Gemini Pro models at a more affordable price. The tradeoff is lower performance than the 3.5 Pro model (coming next month) in tasks that require deep reasoning and high-context understanding."
"Google has reduced the compromise between the Pro and Flash models, saying Gemini 3.5 Flash "delivers intelligence that rivals large flagship models on multiple dimensions." It outperforms the current Gemini 3.1 Pro model on coding and agentic benchmarks like Terminal-Bench 2.1 (76.2 percent), MCP Atlas scaled tool use (83.6 percent) and multimodal understanding with 84.2 percent on CharXiv Reasoning. From an output tokens-per-second standpoint, it's four times faster than other frontier models, according to Google."
"All of that makes 3.5 Flash ideal for long-horizon agentic tasks, completing what used to take weeks in "a fraction of the time," Google wrote. "Under supervision, it can reliably execute multi-step workflows and coding tasks while sustaining frontier performance." It added that partners, including banks and fintechs, have used it to automate multi-week workflows."
"Google noted that 3.5 Flash is now the default model for the Gemini app and for AI Mode in Search worldwide. The personal AI agent Gemini Spark, rolling out to testers today, also runs on 3.5 Flash. At the same time, Google said it strengthened Gemini 3.5's cyber and CBRN (chemical, biological, radiological, nuclear) safeguard so it's less likely to generate harmful content (or mistakenly refuse to answer safe que"
Gemini 3.5 Flash is introduced as a faster default AI model intended to outperform Gemini 3.1 Pro on real-world agentic and coding tasks. It is positioned as delivering frontier-level intelligence without trading quality for latency, while offering lower performance than the upcoming Gemini 3.5 Pro for deep reasoning and high-context understanding. Reported benchmark gains include improvements on Terminal-Bench 2.1, MCP Atlas scaled tool use, and CharXiv Reasoning, along with a four-times faster output tokens-per-second rate versus other frontier models. The model is described as suitable for long-horizon agentic workflows, completing multi-week tasks in a fraction of the time under supervision. Gemini 3.5 Flash is deployed as the default model for the Gemini app and AI Mode in Search worldwide, and it powers Gemini Spark for testers. Safety safeguards for cyber and CBRN content are strengthened to reduce harmful outputs and incorrect refusals.
