Gemma 4 on Antigravity: Picking Q4 vs Q5 — What I Found After a Week on M2 Mac
A hands-on comparison of Gemma 4 quantization variants (Q4_K_M / Q5_K_M / Q8_0 / fp16) running locally with Antigravity on a 16GB M2 Mac, measured across speed, memory, and output quality.
How Far Can Antigravity Maintain a 50M-Download App? A 12-Year Indie Developer's Field Test
I have run wallpaper and wellness apps as an indie developer since 2014, accumulating over 50 million downloads. Here is what Antigravity could and could not take over when I let it maintain that codebase, with the boundary lines I drew.
Giving Your Antigravity AI Agents a 'Time Budget' — A Production Scheduling Design That Unifies Timeouts, Priorities, and Deadlines
Your AI agent's response time creeps up, users drop off, and unexpected costs pile on. This guide walks through giving Antigravity agents a single 'Time Budget' object that unifies timeouts, priority, and deadlines, drawing on Masaki Hirokawa's production experience.
Why Antigravity Agents Can't Read Your .env File — Three Propagation Paths to Check First
When an Antigravity agent fails with Missing API_KEY but the same build works in your terminal, the cause is one of three env propagation paths. Diagnose each.
Splitting AI Context Across Multiple Repos with Antigravity Multi-root Workspaces
When you open multiple similar repos in a single Antigravity window, the AI sometimes pulls conventions from the wrong project. Here is how I split AI context per folder using .antigravity/rules, learned from running four near-identical Next.js sites side by side.
Designing Confidence Scores for Antigravity Agent Outputs: Auto-Approve the Certain, Escalate the Ambiguous
Reviewing every Antigravity Agent output by hand does not scale. Attach a confidence score to each output, auto-approve the certain ones, and only escalate the ambiguous to humans. This guide walks through implementation and threshold calibration end to end.
The Self-Critique Architecture for AI Agents — Four Reflection Patterns That Make Antigravity Outputs Trustworthy
Four production-tested patterns for adding self-critique loops to Antigravity agents, with implementation code, stopping conditions, confidence calibration, and cost-control strategies.
Weekly Picks: Top 5 Must-Read Articles on Antigravity Lab (May 2 – May 8)
A roundup of the five most-read articles on Antigravity Lab from May 2 to May 8, 2026 — covering debugging in the AI agent era, fixing Gemma 4 out-of-memory errors, agent replay design, and UE5 Blueprint workflows.
How to Fix Out of Memory Errors When Using Gemma 4 in Antigravity
Getting out of memory errors when running Gemma 4 in Antigravity? This guide covers how to diagnose the issue and fix it—from switching to quantized models to tuning Ollama settings—based on real troubleshooting experience.
Fixing 'Find References' in Antigravity When Results Are Empty or Incomplete
When Find References returns nothing or only some of the call sites in Antigravity, the cause depends on whether the language server or the workspace index is silent. This guide walks through the diagnosis for TypeScript, Python, and monorepo setups.
Antigravity Meets UE5 Blueprints — Why AI Can't Read .uasset and How I Settled on a Workflow That Works
Antigravity cannot read UE5's binary Blueprint files directly. Here's the hybrid C++ / Python / Blueprint workflow I landed on after building two indie prototypes, plus the patterns I had to abandon.
3 Weeks with Gemini 2.5 Flash as My Default in Antigravity — Speed, Accuracy, and Cost in Practice
What actually changes when you switch from Gemini 2.5 Pro to Flash as your default model in Antigravity? Three weeks of real usage data, including where Flash falls short and when Pro still earns its place.
