Hey HN! I built GPT Image 1.5 (https://gpt-image-15.com https://gpt-image-15.com), a web interface for OpenAI's latest image generation model released Dec 16, 2025. **What it does:** - Text-to-image generation with precise instruction following - Targeted image editing (e.g., "change shirt color" without touching face/background) - Superior text rendering in images (infographics, UI mockups, marketing materials) - 4x faster than previous models (~2min for complex prompts, seconds for simple ones) **Why I built this:** OpenAI released the API but the ChatGPT UI has limitations for power users. I needed: - Batch generation workflows - Style consistency across multiple images - API integration for product mockups - Faster iteration cycles than ChatGPT's interface **Tech stack:** - Next.js 16 (App Router, React Server Components, Turbopack) - React 19 with React Compiler - Tailwind CSS v4 - Better Auth + Drizzle ORM (PostgreSQL) - next-intl for i18n **Benchmarks:** - LMArena ranking: #1 for text-to-image (1264) and editing (1409) - Beats Google Nano Banana Pro in instruction following - 95% semantic matching between prompt and output **Honest limitations:** - Complex prompts still take ~2 minutes (vs seconds for simple ones) - Text rendering improved but not perfect in extreme cases - Inherits OpenAI's content policy restrictions I'd love feedback on the UI/UX, especially from designers and developers using AI image gen in production workflows. Live demo available at the homepage generator - no signup needed for the first 2 images.
