 When using GitHub integration with Runpod, be aware of these important limitations:
 
 * **Build time limit**: Builds must complete within 160 minutes (2.5 hours). Optimize your Dockerfile for efficiency with large images to avoid timeouts.
-* **Image size restriction**: Docker images cannot exceed 100 GB. Plan your image requirements accordingly, particularly when including large model weights or dependencies.
+* **Image size restriction**: Docker images cannot exceed 80 GB. Plan your image requirements accordingly, particularly when including large model weights or dependencies.
 * **Base image limitations**: The integration doesn't support privately hosted images as base images. Consider incorporating essential components directly into your Dockerfile instead.
 * **Hardware-specific builds**: Builds requiring GPU access during construction (such as those using GPU-compiled versions of libraries like `bitsandbytes`) are not supported.
 * **Platform exclusivity**: Images built through Runpod's image builder service are designed exclusively for Runpod's infrastructure and cannot be pulled or executed on other platforms.
