Google Interactions API managed agents will soon support Gemini 4.0 Pro
Google's developer post says Managed Agents on the Interactions API run the Antigravity harness in a remote Linux sandbox with one call, currently on Gemini 3.8 Flash with 4.0 Pro coming soon.
Building production agents shouldn't require wiring up custom orchestration loops and container infra from scratch. With Managed Agents on our Interactions API, a single call spins up the Antigravity harness (Gemini 3.8 Flash and soon 4.0 Pro!) in an isolated remote Linux sandbox—ready to reason, run code, manage files, and browse the web: pythoninteraction = client.interactions.create( agent="antigravity-preview-09-2026", input="Audit this repo and generate a patch.", environment="remote" ) Extend it with your own AGENTS.md & SKILL.md or run async with background=True.
