This is awesome news. I would expect that we would probably see normal Lambda functions eventually follow suit to the 1ms pricing model, or at the very least, something like 10ms incremenets.

For those who aren't super familiar with AWS, this announcement only covers "Lamda@Edge", this isn't the "normal" Lamda serverless function service. These are Lamda functions running at AWS Edge Locations, which are hundreds of CDN endpoints around the world. Lamda@Edge have various restrictions on what they can do, compared to the main Lambda service. They can only be triggered by CloudFront (AWS' CDN service). You could think of them as a "lite" version of Lambda. They are generally used for basic tasks like renaming/manipulating HTTP headers coming into the CDN. So they tend to run in just a few milliseconds.

Normal Lambda are currently billed in 100ms increments. But it would be great to see this come down. I run a few Lambda functions that take < 10ms to run and it would be nice to be able to get 10x the invocations than I am getting on them now because I have to pay the 100ms rate for a 10ms invocation. Granted its all so cheap, even at scale, that its hard to complain too much.
