Show HN: UniWorld V2 – Region-Aware AI Image Editing with RL Accuracy

2•lu794377•1h ago
I built UniWorld V2, a next-generation AI image editing model that understands regions, text, and context — all in one coherent workflow.

Unlike typical diffusion editors, UniWorld V2 applies precise regional edits, integrates reinforcement-learning feedback (Edit-R1), and treats text as a native visual element — not just texture.

Key Features

• Region-Aware Editing – Mask any area, apply a prompt; lighting and global coherence stay intact.

• RL-Enhanced Accuracy (UniWorld-R1) – MLLM-based reward model improves intent alignment and edit quality (outperforms GPT-Image-1, Nano Banana, Gemini).

• Multi-Round Edit Consistency – Edit → re-edit → refine without style drift.

• Advanced Typography Editing – Insert or replace text while preserving font, spacing, and perspective.

• Precision Object Control – Move, add, remove, or replace objects with explicit commands.

Use Cases

Ad & social asset localization

Product & UI iteration

Education / L&D content

Editorial & newsroom visuals

E-commerce & creator workflows

UniWorld V2 combines region-aware control, RL precision, and advanced typography — setting a new benchmark for AI-powered image editing tools.

Would love feedback from the HN community — especially around usability, edit stability, and RL feedback design.
