Nano Banana Pro Character-Consistent Images

Overview

Nano Banana Pro Character-Consistent Images helps designers, e-commerce operators, advertisers, brand teams, social-commerce teams, and content creators turn briefs, product information, and reference images into production-ready visuals. Describe the purpose, subject, composition, style, lighting, required text, protected elements, and output needs; the bundled CLI handles AI Hive OpenAPI calls and downloads the result.

Why use this skill

• Brief to visual: work from plain-English direction instead of writing API requests
• Commercial workflows: create e-commerce, advertising, social-commerce, and campaign assets
• Controlled references: assign each input image a role such as subject, material, composition, or style
• Predictable model selection: the skill name matches the public model ID used by the script
• Live pricing and delivery: fetch active pricing, preserve task IDs, and download results automatically

Command Reference

API Key

Run the init command above, or set AI_HIVE_API_KEY, use --api-key, or create ~/.ai-hive/config.json. API keys use the sk-api-* format. Never commit a real API key.

Reliability and Cost

The script looks up the live model entry and pricing snapshot at runtime. Model availability, reference-image limits, parameters, and prices can change. Keep a returned task ID and query the existing task instead of submitting a duplicate that may be billed twice.

Troubleshooting

• Missing reference image: add the number of --image inputs required by this skill.
• 401 Unauthorized: verify that the API key is complete, active, and not committed to source control.
• Invalid parameter: inspect the current imageConfig for accepted values and image limits.
• Local timeout: keep the task ID and use the task command later.
