Google I/O 2026 had one headline above everything else. At Google I/O, Google released Gemini 3.5 — its latest series of models combining frontier intelligence with action, representing a major leap forward in building more capable, intelligent agents. The first model in the family, Gemini 3.5 Flash, is available today — and the numbers it posts make every other frontier model look slow.

Gemini 3.5 Flash — What It Actually Does
Gemini 3.5 Flash delivers intelligence that rivals large flagship models on multiple dimensions, at the speeds expected from the Flash series. It outperforms Gemini 3.1 Pro on challenging coding and agentic benchmarks including Terminal-Bench 2.1 (76.2%), GDPval-AA (1656 Elo), and MCP Atlas (83.6%), while leading in multimodal understanding at 84.2% on CharXiv Reasoning. When looking at output tokens per second, it is 4 times faster than other frontier models.
That last number — 4x faster than frontier competitors — is the one that matters most for developers building production systems.
Landing in the top-right quadrant of the Artificial Analysis index, 3.5 Flash delivers frontier-level intelligence at exceptional speed — proving you no longer have to trade quality for latency.
The Antigravity Engine: Multi-Agent Workflows at Scale
When coupled with the updated Antigravity harness, 3.5 Flash becomes a powerful engine for deploying collaborative subagents to tackle problems at scale for the most demanding use cases. Under supervision, it can reliably execute multi-step workflows and coding tasks while sustaining frontier performance.
The demos shown at I/O are worth noting in concrete terms:
Powered by Antigravity, 3.5 Flash uses two agents to synthesise the AlphaZero paper and code a fully playable game in six hours. It can also execute multi-step workflows to automatically rename and categorise unstructured assets based on dynamic criteria, and use subagents to transform a messy legacy codebase to Next.js.
For developers and enterprises, this is less a model announcement and more a workflow platform announcement.
Real Businesses, Real Results
Partners already using 3.5 Flash in production include Shopify, running subagents in parallel to analyse complex merchant data for more accurate global growth forecasts; Macquarie Bank, piloting customer onboarding acceleration by reasoning over complex 100-page-plus documents with low latency; and Salesforce, integrating 3.5 Flash into Agentforce to deploy multiple subagents that retain context and execute complex, multi-turn tool calls.
Xero is deploying agents to autonomously manage complex, multi-week workflows such as identifying suppliers and gathering information for 1099 tax forms, enabling small businesses to automate tedious admin tasks. Databricks is using agentic workflows to monitor real-time information, reason across massive datasets to diagnose issues and propose solutions for data scientists.
Gemini Spark: Your 24/7 Personal AI Agent
The biggest consumer announcement built on 3.5 Flash is Gemini Spark.
Gemini Spark, your personal AI agent, uses 3.5 Flash and runs 24/7, helping you navigate your digital life and taking action on your behalf while under your direction. Google is starting to roll out Gemini Spark to trusted testers today, with plans to bring the Beta to Google AI Ultra subscribers in the US next week.
For Indian users already using Gemini Intelligence features on Android 17, Spark is the next layer — a persistent agent that does not wait for you to open an app before it starts working.
What About Gemini 3.5 Pro?
Google is already hard at work on 3.5 Pro. It is already being used internally, and Google is planning to roll it out next month. Given that 3.5 Flash already outperforms 3.1 Pro on multiple benchmarks, the performance ceiling 3.5 Pro represents is substantial.
Pricing and Availability
Gemini 3.5 Flash is generally available via Google Antigravity, the Gemini API in Google AI Studio and Android Studio, Gemini Enterprise Agent Platform, and Gemini Enterprise. It is also now the default model for the Gemini app and AI Mode in Search globally. What used to take a developer days or an auditor weeks, 3.5 Flash can now help complete in a fraction of the time, often at less than half the cost of other frontier models.
For developers in India building on Google Cloud AI or evaluating alternatives to Claude on AWS, Gemini 3.5 Flash’s combination of frontier performance and competitive pricing makes it the most practically deployable model Google has ever released.
The Bottom Line
Gemini 3.5 Flash is not an incremental update to the Flash series. It outperforms a previous flagship, runs 4x faster than comparable frontier models, ships with a multi-agent orchestration platform, and already has Fortune 500 enterprise deployments running in production.
Built in accordance with Google’s Frontier Safety Framework, with strengthened cyber and CBRN safeguards and new interpretability tools that check the AI’s inner reasoning before it responds — this is Google’s most complete and capable model release to date.
The agentic era is not coming. It arrived today.
