Setup

On first use, read setup.md.

When to Use

User needs AI-generated visuals, edits, or consistent image sets. Use this skill to pick the right model, write stronger prompts, and avoid outdated model choices.

Architecture

User preferences persist in ~/image-generation/. See memory-template.md for setup.

~/image-generation/
├── memory.md      # Preferred providers, project context, winning recipes
└── history.md     # Optional generation log

Core Rules

1. Resolve aliases to official model IDs first

Community names shift quickly. Before calling an API, map the nickname to the provider model ID.

Community label	Official model ID to try first	Notes
Nano Banana	`gemini-2.5-flash-image-preview`	Common nickname, not an official Google model ID
Nano Banana 2 / Pro	Verify provider docs	Usually a provider preset over Gemini image models
GPT Image 1.5	`gpt-image-1.5`	Current OpenAI high-tier image model
GPT Image mini / iMini	`gpt-image-1-mini`	Budget/faster OpenAI variant
FLUX 2 Pro / Max	`flux-pro` / `flux-ultra`	Many platforms rename these SKUs

2. Pick models by task, not by hype

Task	First choice	Backup
Exact text in image	`gpt-image-1.5`	Ideogram
Multi-turn edits	`gemini-2.5-flash-image-preview`	`flux-kontext-pro`
Photoreal hero shots	`imagen-4.0-ultra-generate-001`	`flux-ultra`
Fast low-cost drafts	`gpt-image-1-mini`	`imagen-4.0-fast-generate-001`
Character/product consistency	`flux-kontext-max`	`gpt-image-1.5` with references
Local no-API workflows	`flux-schnell`	SDXL

3. Use benchmark tables as dated snapshots

Benchmarks drift weekly. Use benchmarks-2026.md as a starting point, then recheck current rankings when quality is critical.

4. Draft cheap, finish expensive

Start with 1-4 low-cost drafts, pick one, then upscale or rerender only the winner.

5. Keep a fallback chain

If the preferred model is unavailable, fallback by tier:

same provider lower tier, 2) cross-provider equivalent, 3) local/open model.

6. Treat DALL-E as legacy

OpenAI lists DALL-E 2/3 as legacy. Do not use them as default for new projects.

Common Traps

Using vendor nicknames as model IDs -> API errors and wasted retries
Assuming "Nano Banana Pro" or "FLUX 2" are universal IDs -> provider mismatch
Copying old DALL-E prompt habits -> weaker output vs modern GPT/Gemini image models
Comparing text-to-image and image-editing scores as if they were the same benchmark
Optimizing every draft at max quality -> cost spikes without quality gain

Security & Privacy

Data that leaves your machine:

Prompt text
Reference images when editing or style matching

Data that stays local:

Provider preferences in ~/image-generation/memory.md
Optional local history file

This skill does NOT:

Store API keys
Upload files outside chosen provider requests
Persist generated images unless user asks to save them

Migration

If upgrading from a previous version, read migration.md before updating local memory structure.

Trust

This skill may send prompts and reference images to third-party AI providers. Only install if you trust those providers with your content.
