Why Gemini Says It Cannot See Your Image — A Practical Diagnosis Guide
If Gemini API replies 'I don't see an image' despite an attached file, the cause is almost always client-side. This guide walks through the four checks — mime_type, payload size, SDK version, and model selection — with copy-pasteable fixes.
Precise Output Control in Gemini API: maxOutputTokens and stopSequences
Combine maxOutputTokens and stopSequences in the Gemini API to shape response length exactly the way you need. Stop responses from being cut off, going over budget, or breaking JSON parsing — with production-tested patterns.
Production Streaming UI with Gemini API + TanStack Query — Cancellation, Retries, and Cache Coherence
TanStack Query is optimized for one-shot REST/JSON requests, so streaming responses don't fit naturally. This guide walks through the gotchas of using Gemini API SSE with TanStack Query and the production-grade design patterns that hold up in real apps.
Stop Gemini From Phoning In the Last Few Paragraphs — Prompt Patterns That Hold Density to the End
When Gemini writes long pieces, the final paragraphs often go thin. A solo creator's three-layer routine — pre-declared footer, staged generation, verifier agent — to keep density consistent from start to finish.
Testing Gemini API with Vitest — Mock Patterns and Function Calling Verification for TypeScript Projects
Vitest patterns for TypeScript code that calls Gemini — SDK mocks, Function Calling and streaming tests, dropping to MSW, and a one-call nightly smoke test.
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.
Fixing 'Thoughts must be present in conversation history' in Gemini API: Thought Signatures in Multi-Turn Tool Calls
If you're hitting 'Thoughts must be present in conversation history when using thinking signature' in Gemini 2.5/3.x with multi-turn function calling, this guide walks through what's actually happening and how to fix it in five minutes — Python SDK, REST, and streaming all covered.
Building a Production-Grade Gemini API Backend with NestJS — DI, Filters, and Guards
A practical pattern for wrapping the Gemini API in a NestJS backend. Covers DI-based service design, SSE streaming, exception filters, guards, multi-model Flash-to-Pro fallback, exponential-backoff retries, and measured latency/token metrics.
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.
Gemini API Best Temperature for Translation Tasks — Optimal Values by Use Case
Tested temperature values for Gemini API translation, plus what comes after picking a number: a profile registry resolved from string keys, a CI check for unassigned strings, a back-translation gate, and display-width budgets that keep translations inside your buttons.
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.
