properly. So, what is the answer? If you wait 3 and 1/2 months, we are awarded with a new model in the market. So, we can easily swap models. If you wait perhaps 1 year, we have new chips. We have faster GPUs. And again, writing code is easy. So, we have new from frameworks every day. So, you can swap your framework every now and then. So, how do we in real time fix these production bugs? The answer is your dev loop velocity. The model capability increases very exponentially. And the developers have to spend a lot of time every day to automate your developer loop. So, I'm talking about four primitives here. All of you need to think about loops. And at the end of the session, I hope you can 10x your production code.
