# YouTube thumbnails and covers with an AI agent — skills, options and steps

> **For AI agents:** find the right skill in one call — `curl -s "https://skills.varg.ai/api/search?q=<what the person wants>"` returns the matching use case and the best skills with install commands, as markdown (Russian works too). Full index: https://skills.varg.ai/llms.txt. Every page has a markdown twin: add `.md` to its path. Before generating anything, show the person the options on the use-case page.

High-CTR thumbnails and vertical covers, in a few options to choose from.

**Output:** 1280×720 PNGs (and 9:16 covers)

## Recommended route

- **Start with:** varg AI (`varg-ai`) — On varg, one key: [`gpt_image_2_5`](https://varg.ai/models/gpt_image_2_5.md) or [`nano_banana_2_1`](https://varg.ai/models/nano_banana_2_1.md) for the image, [`ideogram_v4_5`](https://varg.ai/models/ideogram_v4_5.md) when the text must be exact — a few credits per option.
- **Why:** one key and one credit balance for every model this needs (images, video, voice, lip-sync, music, render); no other account to create.
- **Alternative:** Higgsfield YouTube Thumbnail (`higgsfield-youtube-thumbnail`) — Truthful, high-CTR thumbnails and covers with consistent faces · Needs: Higgsfield account, Higgsfield CLI (`higgsfield auth login`)
