Observing Antigravity AI Agents with Langfuse — A Practical Setup Before You Ship
Before you push an Antigravity AI agent to production, wire up Langfuse so you can actually see traces, token spend, and cost. A hands-on guide with real Python code and lessons from the field.
Keeping the Antigravity Python API Stable in Production — Retries, Timeouts, and Circuit Breakers That Actually Work
A deeply practical guide to keeping Python services built on the Google Gen AI SDK alive under real traffic. We cover retry, timeout, circuit breaker, rate limit, and cost budgeting patterns with runnable code from an Antigravity workflow.
Build a CSV Analysis Agent in Antigravity with pandas and Matplotlib
Walk through building an Antigravity agent that analyzes CSV files from natural-language instructions. Covers the pandas tool design, common pitfalls, and safety practices for production use.
Prompt Injection Defense in Antigravity — A Production Security Playbook for LLM Apps
A practical, code-first guide to defending LLM applications against prompt injection inside Antigravity. Covers direct, indirect, and multi-turn attacks with working Python implementations of a four-layer defense.
Memory Budget Design for Embedding Gemma 4 in Mobile Apps
When embedding Gemma 4 into a mobile app, peak memory during inference — not the model file size — becomes the real bottleneck. A memory budget design based on measured values, plus a device-tier switching strategy.
Diagnosing and Stopping Runaway Agent Loops in Antigravity
Build agents with Antigravity and you will eventually meet the 'same tool called twenty times in a row' problem. Here is how to classify the failure mode and stop it at the implementation level.
Three Safeguards Every Antigravity Python API Deployment Needs Before Production
Retries, timeouts, and circuit breakers — the three production safeguards you need around your Antigravity Python API calls, with working code for each.
Running Multiple Gemma 4 LoRAs in Production — A Practical Guide to Merging and Dynamic Adapter Switching
You've trained three LoRAs on Gemma 4 — one for summarization, one for translation, one for code review. Now the real question: how do you serve them in production without tripling your GPU bill? This is my working notebook on merging and dynamic switching, written with Antigravity alongside.
Antigravity Walkthrough Won't Load? A Field Guide to Fixing Empty or Frozen Panels
Your Walkthrough panel is blank, stuck on loading, or showing old data. Here's how to diagnose the real cause — cache, sync, or network — and get it working again.
Fixing Antigravity Connection Errors Behind Corporate Proxies and Firewalls
Antigravity works fine at home but fails to sign in or reach the Gemini API on your office network. This guide walks through reading the logs, configuring HTTP proxies, trusting corporate CAs, and getting domain allowlisting right.
Harness Engineering for Antigravity — Turning an Agent into a Project Executor
A deep dive into 'harness engineering' for Antigravity — the prompt-and-template design that makes an agent complete a project, not just answer a question.
Antigravity's April 2026 Quota Relief — What Pro and Ultra Users Can Finally Do
Google expanded AI Studio quotas in April 2026, and Antigravity got the same relief. A developer-eye view of what actually changes for paid subscribers.
