Gemini 3 Pro Image Size Parameter Request For OpenRouter

by Alex Johnson 57 views

We're diving into a crucial discussion regarding the OpenRouter API and the integration of the image_size parameter for the google/gemini-3-pro-image-preview model. This enhancement would significantly expand the capabilities of image generation, offering users greater control over the output resolution and quality. Let's explore the current functionality, the proposed addition, and the benefits it would bring to the OpenRouter community.

Current Functionality and Limitations

Currently, when generating images using the OpenRouter API with the google/gemini-3-pro-image-preview model, users can specify certain image configurations. The existing implementation supports the aspect_ratio parameter within the image_config object. This allows for adjustments to the image's proportions, such as setting it to a widescreen format of "16:9." The code snippet below illustrates how this is currently used:

{
 "model": "google/gemini-3-pro-image-preview",
 "endpoint": "/chat/completions",
 "modalities": ["image", "text"],
 "image_config": {
 "aspect_ratio": "16:9"
 }
}

While the aspect_ratio parameter offers some level of customization, it lacks the crucial ability to control the image resolution. This is a significant limitation for users who require specific resolutions for their projects. For instance, different applications may necessitate images in 1K, 2K, or 4K resolutions. Without the image_size parameter, users are left with a one-size-fits-all approach, which may not meet their diverse needs. This limitation impacts the versatility of the OpenRouter API and its ability to cater to a wide range of image generation requirements.

Proposed Enhancement: Introducing the image_size Parameter

The core of this discussion revolves around the proposal to introduce the image_size parameter within the image_config object. This new parameter would empower users to request images in specific resolutions, such as 1K, 2K, or 4K. This enhancement would provide a much-needed level of granularity and control over the image generation process. By allowing users to specify the desired resolution, the OpenRouter API can better serve a broader spectrum of use cases and applications. The inclusion of the image_size parameter directly addresses the current limitations and significantly improves the flexibility of the API. The impact of this addition would be felt across various domains, including graphic design, content creation, and scientific visualization, where specific resolutions are often critical.

Benefits of the image_size Parameter

  • Enhanced Control: The primary benefit of the image_size parameter is the enhanced control it offers to users. By specifying the desired resolution, users can ensure that the generated images meet their exact requirements. This level of precision is crucial for professional applications where image quality and resolution are paramount.
  • Improved Versatility: Adding the image_size parameter would significantly improve the versatility of the OpenRouter API. It would enable the API to cater to a wider range of use cases, from generating thumbnails and smaller images to producing high-resolution visuals for print or large displays. This versatility makes the API a more valuable tool for a diverse user base.
  • Optimized Resource Utilization: Specifying the image size can also lead to optimized resource utilization. By requesting only the necessary resolution, users can avoid generating unnecessarily large images, which can save on processing time and storage space. This efficiency is particularly important for applications that involve generating a large number of images.
  • Better User Experience: The image_size parameter contributes to a better user experience by providing a more intuitive and customizable interface. Users can easily adjust the resolution to fit their needs, streamlining the image generation process and reducing the need for post-processing or resizing.

Code Example with image_size

To illustrate how the image_size parameter would be used, consider the following code snippet:

{
 "model": "google/gemini-3-pro-image-preview",
 "endpoint": "/chat/completions",
 "modalities": ["image", "text"],
 "image_config": {
 "image_size": "4k"
 }
}

In this example, the image_config object now includes the image_size parameter set to "4k". This would instruct the OpenRouter API to generate an image with a 4K resolution. The simplicity and clarity of this implementation make it easy for users to integrate the image_size parameter into their workflows. By providing a straightforward way to specify the resolution, the API becomes more accessible and user-friendly.

Discussion and Community Input

This proposal is open for discussion and community input. We encourage users and developers to share their thoughts and suggestions on how the image_size parameter should be implemented and what resolution options should be supported. Feedback from the community is invaluable in ensuring that the OpenRouter API meets the needs of its users. This collaborative approach will help refine the proposal and ensure that the final implementation is as effective and user-friendly as possible. We believe that a robust discussion will lead to a better outcome for everyone involved.

Key Discussion Points

  • Supported Resolutions: What resolutions should be supported by the image_size parameter? Should there be a predefined set of options (e.g., 1K, 2K, 4K), or should users be able to specify custom resolutions?
  • Default Resolution: What should be the default resolution if the image_size parameter is not specified? A reasonable default resolution would ensure that images are generated even if the user does not explicitly set the size.
  • Error Handling: How should the API handle invalid image_size values? Proper error handling is crucial to prevent unexpected behavior and provide informative feedback to the user.
  • Performance Considerations: How will the image_size parameter impact the performance of the API? It's important to consider the computational resources required to generate images at different resolutions and optimize the implementation accordingly.

Conclusion: Enhancing OpenRouter with Granular Image Control

In conclusion, adding the image_size parameter to the OpenRouter API for the google/gemini-3-pro-image-preview model represents a significant enhancement. It addresses the current limitations by providing users with the ability to request specific image resolutions, thereby increasing the API's versatility and utility. This improvement is crucial for meeting the diverse needs of users in various fields, from graphic design to scientific research. The proposed implementation is straightforward and user-friendly, ensuring that the image_size parameter can be easily integrated into existing workflows. We encourage the OpenRouter community to actively participate in the discussion and provide feedback to ensure the successful implementation of this feature. By working together, we can make the OpenRouter API an even more powerful and flexible tool for image generation.
