Tokens, turns and time describe resource use, not a dollar price.

This benchmark measured an earlier version of the skill.

A newer attempt on gemini-3.6-flash on 10/2/2026 did not produce a publishable comparison (not comparable). The snapshot above is the previously measured run.

Prompt

When invoking `executors/generate-image/generate-image.mjs` to generate `header.png` from `header.txt`, we want to explicitly select OpenAI's image model rather than defaulting. What specific model identifier must be passed with the `--model` flag?

What was checked, without and with the skill

Generate images

Use executors/generate-image/generate-image.mjs for text-to-image and reference-image editing. It is a repository-owned, zero-dependency Node.js client. Do not call Codex system Skills, private scripts, or files under ~/.codex.

Define the asset

Specify:

placement and purpose;
subject and visible action;
composition and aspect ratio;
visual style and brand palette;
exact text when text is essential;
details that must appear;
artifacts, logos, watermarks, and unrelated text to exclude.

Prefer real product screenshots when the image explains product behavior. Use generated visuals for concepts, scenes, covers, illustrations, diagrams, and supporting examples.

Generate

Use a prompt file for long or multilingual prompts:

node executors/generate-image/generate-image.mjs \
  --out <output.png> --prompt-file <prompt.txt>

Choose OpenAI explicitly when appropriate:

node executors/generate-image/generate-image.mjs \
  --model gpt-image-2 --out <output.png> \
  --prompt-file <prompt.txt>

--model accepts any gpt-image-* ID (sent to the OpenAI Images API at OPENAI_BASE_URL) or any gemini-*image* / nano-banana* ID (sent to the Gemini API at GOOGLE_GEMINI_BASE_URL). Compatible gateways may expose suffixed or tiered model IDs; list them with the gateway's /v1/models before choosing.

Add one --ref <image> argument for each reference image used in an edit.
