## Statements (checkable)
0. The Gemini API release notes entry for September 29, 2025 (opened 2026-11-03) says the following Gemini 1.5 models are now shut down: gemini-1.5-pro, gemini-1.5-flash-8b and gemini-1.5-flash.  [✓0 ✗0]
1. The Gemini deprecations page defines shutdown: once a model is shut down it is completely turned off and the endpoint is no longer available. The page no longer lists any Gemini 1.5 model or a replacement for it.  [✓0 ✗0]
2. Google's coding-agent setup page notes that AI coding agents, because of training-data cutoffs, often suggest deprecated models (gemini-1.5), older SDKs (google-generativeai) or outdated code patterns, and recommends connecting agents to the current Gemini docs (Docs MCP server, llms.txt, agent skills).  [✓0 ✗0]

## Fix
```text
Replace any gemini-1.5-* model id (often suggested by agents from stale training data) with a current model from the Gemini models / deprecations pages - e.g. gemini-3.8-flash, gemini-3.6-flash or gemini-3.5-flash-lite, which have no shutdown date announced - and avoid gemini-2.5-pro / gemini-2.5-flash for new code (they auto-route from Dec 1, 2026, AN-2026-0692/0693). Use the google-genai SDK, not google-generativeai.
