Google Launches Gemini 3.5 — AI Dev Pulse · May 20, 2026

Google’s annual developer conference wrapped its second day yesterday with a decisive pivot from assistive AI to fully agentic systems that can independently orchestrate complex workflows across terminals, IDEs, and cloud services. The standout release—Gemini 3.5 Flash—ships today with frontier-level reasoning at four times the speed of prior comparable models, a 1 M context window, and measurable gains on Terminal-Bench 2.1 and agentic coding tasks. Paired with Antigravity 2.0, the new agent-first platform now includes a dedicated CLI, cross-platform sandboxing, and credential masking that lets teams spin up specialized subagents without exposing secrets or violating Git policies.

These updates matter because they collapse the gap between prototype agents and production-grade tooling. Android developers can now hand an agent stable CLI access to Android Studio, open-sourced skills for Jetpack Compose migrations, and a preview migration agent that converts weeks of React Native or iOS work into hours. On the web side, the proposed WebMCP standard and agent-aware Chrome DevTools give browsers the same structured tool exposure that terminal agents already enjoy. The net result is a measurable reduction in context-switching overhead for any team shipping AI-augmented mobile or web products.

Top Stories

Gemini 3.5 Flash reaches general availability Practical dev impact: Swap in the new model today for 4× faster inference on coding and agent tasks while keeping a full 1 M context window and paying $1.50 / $9 per million input/output tokens.

Antigravity 2.0 ships with CLI and subagent orchestration Practical dev impact: Run `antigravity` from any terminal to launch isolated subagents behind sandboxing, credential masking, and hardened Git policies—no additional infrastructure required.

Agent-native Android and web tooling lands at I/O Practical dev impact: Point agents at the new stable Android CLI and open-sourced skills to automate SDK installs, Jetpack Compose migrations, and real-time DevTools audits without leaving the agent loop.

Practical Impact Analysis

On the mobile side, the open-sourced Android skills and migration agent preview remove the last major friction in moving legacy codebases into modern Kotlin + Jetpack environments. Web developers gain an early standard (WebMCP) that lets any browser-based agent call structured functions reliably, something previously limited to custom browser extensions. The net effect is that full-stack teams can now maintain a single agent surface across terminal, Android Studio, and Chrome DevTools instead of stitching together separate tools.

Recommended Tutorial Idea

1. Install the CLI: `npm install -g @google/antigravity-cli`. 2. Authenticate and create a managed agent: `antigravity agent create –model gemini-3.5-flash –name android-migrator`. 3. Attach the open-sourced migration skill: `antigravity skill install android-migration-preview`. 4. Run the agent against a sample React Native project:

antigravity run --task "Migrate this React Native app to native Kotlin Jetpack Compose" \
  --input ./my-app \
  --output ./migrated-app \
  --sandbox

antigravity run --task "Migrate this React Native app to native Kotlin Jetpack Compose" \
  --input ./my-app \
  --output ./migrated-app \
  --sandbox

5. Review the generated migration report in Android Studio and iterate with `antigravity agent chat`.

The agent will analyze the codebase, propose Kotlin equivalents, run the migration preview, and hand off a ready-to-build project.
