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.
9 Patterns for Automating Daily Work with Gemini Gems — Turning Custom Instructions Into Real Tools
Built a few Gems but only end up using one or two? You're not alone. Here are nine patterns that share what actually-used Gems have in common, with the custom-instruction shape for each.
Five Design Decisions to Make Before Putting gemini-2.5-pro-latest in Production
Running gemini-2.5-pro-latest in production is more than picking a fast model. Here are the five design decisions — versioning, retry, cost, fallback, observability — that I now resolve before any new service ships.
From Free Tier to First Paying User with the Gemini API — Three Walls Indie Devs Hit
Reaching 'it works' with the Gemini API is easier than ever. Reaching 'someone paid for it' is a different problem entirely. Here are the three non-technical walls indie developers hit before their first paying user — with the minimal code that wires payment to key issuance.
Gemini API Temperature Best Practices by Task — Translation, Summarization, Code, Chat, and More
The `temperature` parameter is one of the highest-leverage knobs in the Gemini API, yet most implementations ship with the default. This guide walks through the value I actually use for each task type — translation, summarization, code generation, chat, classification — and explains why.
Build an Auto-Documentation Pipeline with Gemini API and GitHub Actions
Tired of outdated docstrings and READMEs? This guide shows you how to build a CI pipeline that uses Gemini API and GitHub Actions to automatically suggest documentation updates on every Pull Request.
Defending Gemini API Responses with Schema Validation — Never Let Unexpected Formats Reach Production
Gemini's structured output is convenient, but in production the day always comes when an unexpected format slips through. This piece walks through layered Zod/Pydantic validation, repair prompts, and graceful degradation — the defense lines I run on my own apps.
