RunComfy hosts the Wan 2.7 text-to-image integration for Alibaba’s model family. The playground sends the documented keys—prompt, negative_prompt, image_size, max_images, seed, and enable_safety_checker—to the inference route configured for this tool.
RunComfy pricing is $0.03 per generated image. If you set max_images greater than 1, the total scales with how many images the job returns.
Yes. You can write prompts in Chinese or English on this RunComfy playground.
max_images must be an integer from 1 to 5 for this model.
Both use the same parameter names. Standard text-to-image is priced lower and suits drafts and fast iteration; Pro targets higher-fidelity output and a higher per-image price. Pick standard for exploration and Pro when you need final hero frames.
This playground is set up for string presets so inputs map cleanly through the default integration. A custom {width, height} object may work in advanced or API-only setups—confirm in your RunComfy workspace settings before you rely on arbitrary dimensions.
