Playground Free Plan (10 images every 3 hours)
Playground
Free plan: up to 10 images every 3 hours, plus 3 monthly generations shared across Muse Image, Nano Banana, GPT Image 2, GPT Image 2.5 and Seedream, with a world-wide royalty-free commercial license
Official pricing page, Free plan verbatim: "Free · For exploring and casual creation · Limited image generation: Create up to 10 images every 3 hours · Limited model access: 3 monthly generations across Muse Image, Nano Banana, GPT Image 2, GPT Image 2.5, and Seedream · Commercial use: World-wide, royalty free license · Limitations: Slower generation during peak hours. Waiting period after limits are reached." The Pro plan gives up to 75 images every 3 hours and 150 monthly credits, which are paid-plan benefits.
The 10 images every 3 hours are consumed by the default Auto model (the official page says free users default to Muse Image, except transparent images); choosing another model uses the 3 monthly generations. Generation is slower at peak hours and you must wait after hitting a limit. The official FAQ forbids using multiple accounts to get around free limits, and shared public networks can trigger a false warning. Reachability from mainland China was not tested.
