Frequently Asked Questions
Can I use Grok AI Image Generator outputs from the text-to-image feature for commercial purposes?
Yes, Grok AI Image Generator allows commercial use of its text-to-image outputs if you have an appropriate paid license. However, using the model through RunComfy does not override xAI’s model license terms. Always review the original license (such as OpenRAIL or similar) to ensure compliance with xAI’s stated commercial usage rights.
What licensing terms apply when using Grok AI Image Generator via RunComfy?
When you generate text-to-image content using Grok AI Image Generator on RunComfy, you must still adhere to the original model creator’s licensing—typically a custom or Open RAIL-style license provided by xAI. RunComfy merely offers a managed interface and GPU service, but it does not transfer any new rights or waive existing license restrictions.
What are the technical limitations of Grok AI Image Generator when using the text-to-image mode?
For text-to-image generation, Grok AI Image Generator supports resolutions up to 4K (depending on subscription) with common aspect ratios like 1:1, 16:9, and 9:16. Prompt tokens are limited to around 400–500 characters, and multimodal inputs allow up to two reference images for feature-guided generation (e.g., via ControlNet/IP-Adapter).
How can developers move from trying Grok AI Image Generator in the RunComfy Playground to full API integration?
Developers can start with the RunComfy Playground to test text-to-image features of Grok AI Image Generator, then switch to the RunComfy Production API for automation. The API uses similar parameters (prompt, style, resolution) and accepts user authentication tokens for production workloads. Documentation and endpoint examples are available from RunComfy’s developer portal.
What makes Grok AI Image Generator better than previous versions or similar tools?
Grok AI Image Generator, powered by the Aurora model, outperforms earlier Grok image versions with more accurate text-to-image rendering, improved photorealism, and better prompt fidelity. Its autoregressive mixture-of-experts design produces clean facial details and brand elements where earlier or competing models often struggle.
What kind of latency or throughput can I expect when using Grok AI Image Generator’s text-to-image function through RunComfy?
Most text-to-image generations complete within 6-8 seconds. High concurrency scenarios may queue briefly, but cloud orchestration keeps throughput consistent even during peak hours.
Does Grok AI Image Generator provide a free trial for its text-to-image functionality on RunComfy?
Yes, new RunComfy users receive complimentary USD credits to try Grok AI Image Generator and its text-to-image feature. After the trial credits expire, additional usage requires purchasing credits through the RunComfy billing panel.
Who should I contact for technical or licensing questions about Grok AI Image Generator?
