## Trade-off
|
||||
|
||||
While this is a nice feature to have, there's a trade-off. Each OG image takes roughly one second to generate. This might not be noticeable at first, but as the number of blog posts grows, you might want to disable this feature. Since every OG image takes time to generate, having many of them will increase the build time linearly.
|
||||
|
||||
For example: If one OG image takes one second to generate, then 60 images will take around one minute, and 600 images will take approximately 10 minutes. This can significantly impact build times as your content scales.

## Limitations
|
||||
|
||||
At the time of writing this, [Satori](https://github.com/vercel/satori) is fairly new and has not reached major release yet. So, there are still some limitations to this dynamic OG image feature.
