Show HN: JSON Schema for Google Gemini Image Generation

2 points

9 months ago

Been working with Gemini's image generation API and got frustrated with the lack of structure in prompt engineering. Built a JSON schema that validates prompts and ensures consistency.

Includes Python validator, examples covering different use cases (product photography, portraits, illustrations), and simple integration samples.

The schema is quite comprehensive - covers everything from basic subject/style to detailed technical parameters like camera settings and lighting.

Open source (MIT), would appreciate feedback from others working with Gemini or similar models.
