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.
Gemini API Won't Connect Through Corporate Proxy or SSL Verification — A Troubleshooting Walkthrough
Your Gemini API script worked on your personal laptop, but the corporate Windows machine just hangs. Isolate proxy, SSL, and certificate issues layer by layer with working Python and Node.js examples.
