A production-grade design for persisting Gemini API multi-turn conversations with Drizzle ORM. Covers streaming saves, branching threads, function calling history, pgvector integration, and the migration strategy you actually need.
A Personal Secretary AI on Gemini API and Google Workspace — Auth, Orchestration, and Approval Gates
Designing a personal secretary AI across Gmail and Google Calendar with the Gemini API: OAuth2 scope design, Function Calling orchestration, approval gates for write tools, and ninety days of measured production cost, with full Python code.
7 Design Decisions When Wiring Gemini API Into a Solo App — From Error Design to Quality Monitoring
After embedding Gemini API into several of my own apps, I've collected seven design decisions that come up in production but rarely in tutorials — fallback layering, dynamic model switching, latency UX, and lightweight quality monitoring. This is the playbook I use today.
Citation-Grounded RAG with Gemini: Production Patterns for Source Attribution and Hallucination Detection
A practical guide to wiring trustworthy citations into a Gemini-powered RAG pipeline. Covers structured output, post-hoc validation, UI rendering, and a quantitative grounding score you can put on a dashboard.
Why count_tokens Lies: 5 Reasons Your Gemini API Bill Is Higher Than You Estimated — A Reconciliation Playbook
count_tokens said 1,200 tokens. Cloud Console billed you for 4,800. I made the same mistake building my first indie app on Gemini. This guide walks through the five hidden contributors — thinking, tools, multimodal, history, caching — and how to reconcile them with reproducible code.
Production-Grade PII Redaction for the Gemini API — Detection, Masking, and Audit Logging That Actually Pass a Privacy Review
Are you piping raw user text straight into the Gemini API? This guide walks through detection, masking, and audit-log design so you can keep PII out of model traffic and pass GDPR, SOC 2, and customer privacy reviews — with code you can ship today.
Gemini API × Inngest: Building Fault-Tolerant AI Workflows for Production
A practical guide to building durable, fault-tolerant Gemini API workflows with Inngest — covering retries, fan-out/fan-in, human approval, throttling, and dead-letter patterns.
When Gemini API URL Context Returns Nothing: A Diagnostic Walkthrough
If Gemini's URL Context tool stays silent or returns generic answers, the cause is almost always one of three things: tool configuration, URL formatting, or site-side restrictions. Here's how to isolate which.
Dynamic Few-Shot for Gemini API — A Self-Improving Prompt That Picks Examples by Vector Search
Hand-picked, hard-coded few-shot examples stop scaling once your inputs drift. This guide builds a Gemini Embeddings + vector search pipeline that selects the best 3-5 examples per request and grows them from production feedback, with copy-paste code.
Beyond Embeddings: Production Reranking with Vertex AI Ranking and Gemini-as-Judge
When pure embedding search nails the top-3 but buries the right answer at rank 4, you need a reranker. This guide walks through a production-grade two-stage architecture using Vertex AI Ranking API and Gemini-as-judge — with cost, latency, and evaluation patterns that hold up under load.
Building Human-in-the-Loop Workflows with Gemini API — A Production Implementation Guide
Fully automating Gemini API output is risky, but reviewing every response by hand is impractical. This guide walks through a Human-in-the-Loop architecture in three layers — confidence gating, review queues, and feedback loops — at production-implementation depth.
Why Your Gemini File URI Suddenly Returns 404 — Designing Around the 48-Hour TTL
Your Gemini-powered image or video pipeline worked perfectly yesterday, then started returning 404 the morning after a restart. The culprit is the File API's 48-hour TTL. Here is how to detect it and design an app that survives it.
