Summary

Google DeepMind introduced Gemini 3.5, a new family of models combining frontier intelligence with action, with 3.5 Flash released on May 19, 2026. This model excels at complex, long-horizon agentic workflows and coding, delivering performance that rivals large flagship models while being four times faster in output tokens per second. Gemini 3.5 Flash outperforms Gemini 3.1 Pro on benchmarks like Terminal-Bench 2.1 (76.2%), GDPval-AA (1656 Elo), MCP Atlas (83.6%), and CharXiv Reasoning (84.2%). It is available globally via the Gemini app, AI Mode in Google Search, Google Antigravity, Gemini API, Gemini Enterprise Agent Platform, and Gemini Enterprise. The model also powers Gemini Spark, a personal AI agent, and is being used by partners like Shopify, Macquarie Bank, and Salesforce for automating complex tasks at less than half the cost of other frontier models.

Key takeaway

For AI Engineers and ML Engineers building agentic applications, Gemini 3.5 Flash offers a compelling solution. You can utilize its frontier performance and four times faster output speeds to automate complex, long-horizon workflows and coding tasks, potentially at less than half the cost of alternative models. Consider integrating 3.5 Flash via Google Antigravity or the Gemini API to accelerate development and deploy robust, multi-step agentic solutions for your enterprise.
