Using Gemini in Sheets' One-Click Formula Fix Without Trusting It Blindly
Gemini in Sheets can now diagnose and fix formula errors in one click. It's genuinely fast, but it can also produce 'quiet fixes' that parse cleanly yet return the wrong value. Here is a short verification habit to use it with confidence.
Your Gemini Structured Output Keys Keep Reordering — Pin Them With propertyOrdering
You constrained the shape with responseSchema, yet the JSON key order shifts between calls and your snapshot tests go red for no reason. Here is why field order is not guaranteed by default, how propertyOrdering fixes it, how Pydantic sets it for you, and how to align few-shot examples — all with working code.
Is Gemini 3.5 Flash Actually Cheaper? Measuring Retry Amplification to Find the Flash vs Pro Break-Even
Now that 3.5 Flash is generally available, it is tempting to route everything to it. But once you measure effective cost per success instead of per-call price, the decision changes. Here is a small harness to measure retry amplification and find the break-even.
When Gemini's Safety Filter Silently Drops Legitimate Output — Field Notes on Catching False Positives Without Turning Everything Off
Field notes on handling Gemini API false positives in production without disabling every category. Separating input blocks from output blocks, instrumenting per-category false-positive rates, and recovering by relaxing only the offending category.
When your Gemini API spend cap trips, paying users go down too — isolating the blast radius with per-tier projects
A Project Spend Cap stops the entire project at once. To keep a runaway free tier from taking paying users down with it, this is a design note on isolating the cap's blast radius across per-tier projects and closing the ~10-minute delay with an application-side soft budget gate.
Reliable Text-in-Image with Gemini 3.1 Flash Image — an OCR-Verified Pipeline
After the preview shutdown, the GA gemini-3.1-flash-image still occasionally garbles text baked into images. Here is a generate -> read-back-verify -> regenerate/composite pipeline, with working code and an unattended retry budget.
Turning Articles into Audio with the Gemini 3.1 Flash TTS Preview: Splitting Long Text, Stitching It Back, and What It Actually Costs
The Gemini 3.1 Flash TTS preview launched today. Here is a single-narrator pipeline that converts a written article into clean audio, including how to split long text, stitch PCM without ugly seams, keep one voice steady, and estimate the real per-article cost.
Gemini API × TypeScript Type-Safe AI Application Architecture — Integrating Zod Schemas, Structured Output, and Streaming
Type-safe AI applications with the Gemini API and TypeScript: Zod validation, Structured Output, streaming pipelines, and error handling that holds up in production.
When Gemini's Structured Output Quietly Drifts From Your Schema — Field Notes on Measuring Validation and Retries
Even with response_schema set, Gemini's structured output occasionally drifts in production. Stop swallowing failures, measure them, split causes by finish_reason, and feed errors back for a corrected retry. Field notes from stabilizing a validation pipeline.
The Morning a Preview Image Model Went Dark — Migrating to GA Gemini Image Models and Building a Deprecation-Resilient Pipeline
With gemini-3.1-flash-image-preview and gemini-3-pro-image-preview retired, here is how to migrate to the GA models and design an image pipeline that no longer gets caught off guard by deprecation dates — with code and cost math, plus video-to-image thumbnail automation.

Build native Android AI apps with Kotlin and Jetpack Compose. Covers Google AI SDK, MVVM, multimodal chat UI, Room DB, WorkManager, and production security.
Folding a Local Gemma 4 into Daily Work — Practical Notes on the Ollama API and Response Speed
Taking a local Gemma 4 you can now run interactively and folding it into real work: how to hit Ollama's local API from a script, tricks to improve perceived response speed, and a two-tier fallback that automatically routes to the cloud Gemini API — code included.
