After launching on April 21, 2026, ChatGPT Image 2.0 achieved the top spot on the LMArena Image scoreboard with an Elo score of 1,512 in just 12 hours. That is the biggest margin in Arena’s history, 242 points more than Nano Banana 2. It’s not a close contest. However, in some situations, Nano Banana 2 still prevails.
It operates on gpt-image-2, which has been completely rebuilt rather than being updated to 1.5. The research head at OpenAI called it a “generalist model” – basically, a “GPT for images.”
Key Specifications:
- Text Rendering Accuracy: ~99% (Latin, Hindi, Bengali, and CJK scripts)
- Instant Generation Modes: ~3 seconds + Thinking (justifications prior to creating)
- Maximum Resolution: 4096 x 4096 pixels
- World Knowledge Cutoff: December 2025
- Batch Output: Up to 8 photos per query (Thinking mode)
Thinking mode can search the web in mid-generation for reference material, count things, check limitations, and plan composition.
Instant mode is the free tier. Plus/Pro/Business = Thinking mode.
Nano Banana 2: What Is It?
Gemini 3.1 Flash Image is the official name. It combines Gemini Flash speed with Nano Banana Pro quality.
