Citing the exact page and figure in File Search answers with visual-citation metadata
File Search grounding metadata now carries media_id and page_numbers, so you can trace each sentence of an answer back to a specific page and figure. Here's how I built a sentence-level, verifiable citation layer over a mix of PDFs and images.
Building an Intelligent Data Layer: Gemini API × GraphQL Architecture Guide
A comprehensive guide to integrating Gemini API into GraphQL for AI-powered resolvers, semantic caching, and type-safe schema design. Build production-grade intelligent data layers.
Gemini API × Cloudflare D1: A Zero-Cold-Start AI Backend Under $10/Month — Implementation Notes
Build a zero-cold-start, globally distributed AI backend with Cloudflare Workers + D1 (edge SQLite) and Gemini API — conversation history, rate limiting, post-stream write latency, and a real $8.50/month cost breakdown, from a deployment I actually operate.
When a Deploy Drops the Webhook: Reconciling Gemini Long-Running Operations with a Belt-and-Suspenders Design
Even after you move from polling to Webhooks, events still get dropped during deploys and transient 5xx windows. Here is how I double up Gemini long-running operations with an operation ledger and a low-frequency reconciliation poller so a missing terminal event never goes unnoticed.
Running Gemma 4 Locally on Windows — A Hands-On LLM in Two Commands with Ollama
How to run Google's lightweight open model Gemma 4 locally on a Windows laptop. With Ollama, you go from install to running in effectively two commands. Plus how to split work between the cloud Gemini API and a local Gemma.
When Gemini API Quietly Dies on the Edge from Subrequest Limits — Field Notes on Budgeting What's Left
Running Gemini API on Cloudflare Workers is calm until traffic rises or a tool chain deepens, and then it fails on the subrequest limit. Here are the instrumentation patterns I use to measure per-request consumption and treat it as a budget, drawn from the sites I run as an indie developer.
Stopping Gemini API Function Calling Loops: Why They Happen and How to Break Them
Your tool-calling agent keeps invoking the same function and never finishes. Here is how to diagnose the loop and bake stop conditions into your prompt, code, and tool responses — including catching regressions when the default model changes and detecting result-based stalls.
Your File Search Store Goes Stale in Production — Catalog Sync and Drift Detection That Actually Hold
Load a catalog into File Search once and forget it, and within weeks it starts confidently pointing users at assets you already pulled. Here is the sync pipeline I run: hash-based incremental import, a blue/green rebuild that swallows deletions, and a nightly drift audit.
Integrating Gemini 3.2 Pro Function Calling into iOS/Android Apps: Production Design Patterns
A practical guide to integrating Gemini 3.2 Pro Function Calling into iOS and Android apps. Includes working SwiftUI, Kotlin, and Python code, plus production patterns proven in a real indie wallpaper app — cost, latency, staged rollout, and regression testing.
Your Gemini API Average Latency Looks Great — But Some Users Still Get Stuck. Defending p95/p99
Your average TTFT is fast, yet a fraction of users keep hitting frozen responses. That is a tail-latency problem (p95/p99). From measurement to model routing, streaming budgets, cache accounting, and retry design — here are the defenses that actually held up in production, with code.
Implementing Gemini API Function Calling — Parallel Calls, Tool Chains, and When to Use Managed Agents
Production patterns for Gemini API Function Calling: parallel calls, error handling, and tool chaining, plus when to use Managed Agents and how to pin the tool-selecting model to a GA release.
Generating a Thumbnail From a Video With Nano Banana 2 (gemini-3.1-flash-image)
A hands-on guide to passing a whole video as context to the GA model gemini-3.1-flash-image (Nano Banana 2) and generating a single thumbnail. Covers how it differs from frame extraction, the preview-to-GA migration, and measured cost and time per image.
