Show HN: CLI Image Generation Agent Using (OpenRouter and Free Models)

built a CLI-based image generation agent that takes vague prompts like: “a warrior in a forest” And automatically: Expands it into a detailed cinematic description (lighting, mood, camera angle, art style) Routes it to the appropriate model via OpenRouter Downloads the generated image locally

Tech stack: React Ink (CLI UI) TypeScript Modular subagent architecture OpenRouter (free-tier models supported) One thing I realized while building this: You don’t actually need expensive API credits to experiment with AI agents.

There’s a surprisingly strong free stack available: OpenRouter (multiple free-tier models) Antigravity (Claude, GPT variants, Gemini access) OpenCode (GLM-5, MiniMax) Local models via LM Studio / Ollama / ComfyUI

The biggest barrier isn’t cost — it’s clarity of architecture.
