🤖 AI Agents Weekly: Gemini 3.5 Flash, Antigravity 2.0, Codex Thursday, Cohere Command A+, Qwen3.7-Max, and More

Google launched Gemini 3.5 Flash, a frontier model optimized for agents and coding, alongside Managed Agents in the Gemini API that provide an isolated execution environment. The model achieves state-of-the-art results on agentic benchmarks and is available across multiple Google platforms, positioning Flash as the cost-optimized default for agent workloads.

Top Stories Gemini 3.5 Flash and Managed Agents Land Google opened I/O 2026 with Gemini 3.5 Flash, a frontier model tuned explicitly for agents and coding, alongside Managed Agents in the Gemini API that ship an isolated execution environment with every request. Agentic benchmarks: Gemini 3.5 Flash posts 76.2% on Terminal-Bench 2.1, 83.6% on MCP Atlas, and 1656 Elo on GDPval-AA, outperforming Gemini 3.1 Pro on long-horizon coding and tool-use tasks at 4x faster output. Managed Agents preview: A single Gemini API call spins up an agent that reasons, uses tools, and executes code in an ephemeral Linux sandbox managed by Google, with AGENTS.md and SKILL.md as versionable config. Where it ships: Available in Google AI Studio, Android Studio, Antigravity, Gemini Enterprise Agent Platform, the Gemini app, and AI Mode in Search, with 3.5 Pro slated for next month. Why it matters: Flash is now the cost-optimized agent default at Google scale, and Managed Agents removes the build-your-own-sandbox tax that has kept many teams on third-party runtimes.
