Gemini API Pricing for Monetization — Free Tier, Paid Tiers, and the Pro vs Ultra Decision
Trying to make money with Gemini API? The pricing page alone won't tell you whether your business survives. Here's the Free Tier, paid Tiers 1–3, and Google AI Pro vs Ultra trade-offs read from a revenue operator's point of view.
Mastering Custom Instructions in Gemini Gems — What Actually Works After Two Months of Testing
Custom instructions in Gemini Gems can swing response quality wildly. After running half a dozen Gems for two months, here's what actually moves the needle — and what wastes characters.
Cancelling Gemini API Streams the Right Way — AbortController, asyncio, and the User-Initiated Stop Button
Hitting your chat UI's stop button shouldn't just freeze the screen — it should also stop billing. This guide shows how to wire up AbortController, request.is_disconnected, and the buffered-history pattern so cancellation actually does what users expect.
Making Gemini API Output Reproducible with the seed Parameter — Practical Patterns for Tests and Debugging
A practical guide to using the Gemini API seed parameter to make responses reproducible. Covers Python and Node.js patterns for tests and debugging, plus the cases where seed quietly stops working.
Self-Healing Architecture for Gemini Computer Use — Production Patterns That Keep Browser Automation Alive Beyond Day Three
Gemini Computer Use looks magical in demos but breaks daily in production: vanishing elements, surprise modals, network jitter, off-by-four-pixel clicks. This guide builds a five-layer self-healing architecture in Python that classifies failures and recovers them automatically, with working code you can drop into your agent loop today.
Gemini API × Stripe — Production Usage-Based Billing for Indie AI SaaS
A complete guide to building a usage-based billing system for your Gemini API SaaS using Stripe Metered Billing and webhooks — production patterns included.
When Gemini API Returns Mojibake: 4 Places to Check First
Mojibake in Gemini API responses almost never comes from the API itself — it lives in your client code. Walk through the four layers (HTTP decoding, streaming chunks, output encoding, surrogate pairs) where the corruption hides.
Generating Multilingual Video Subtitles (SRT/VTT) with the Gemini API
A practical pattern for generating SRT/VTT subtitles in multiple languages from a single video file using the Gemini API. Covers timestamp accuracy, JSON schema output, and production pitfalls.
Measuring Classification Confidence with Gemini API Logprobs — A Practical Walkthrough
Use the Gemini API responseLogprobs option to extract per-token confidence scores, then turn them into an auto-vs-review gate for classification — with working Python code and the threshold thinking behind it.
Production-Ready Function Calling with Gemini 2.5 Pro API — Realistic Patterns for Failures, Timeouts, and Hallucinations
Gemini 2.5 Pro's Function Calling is powerful, but it tends to land in 'works, but does odd things sometimes' territory in production. Here are the design patterns I arrived at running search, reservation, and notification agents.
Custom Gemini API Agent Loop Without ADK — A Complete Production Guide to Tool Calling, Memory, and Parallel Execution
Build production-grade AI agents using Gemini API directly without Google ADK. This guide covers custom agent loops, tool calling patterns, sliding window memory, parallel execution, and battle-tested error recovery strategies.
Writing Gemini Gems Custom Instructions That Actually Behave
The way you structure custom instructions for a Gemini Gem changes its behavior dramatically. Here are the patterns I converged on after several Gems and a lot of iteration.
