Steve is now a C++ celebrity!
- Steve Bronder. 2025. From Bayesian inference to LLMs: Modern C++ Optimizations for Reverse-Mode Automatic Differentiation. CppCon.
The production values for these are top notch. They’re also highly Google ranked, so you can’t miss them when you search for advanced C++ topics.
Steve’s been writing C++ code for Stan since before the pandemic. He now works with me at Flatiron Institute as a software engineer. He joined the Stan team after taking a GPU class and asking us if we had any use for GPUs. We said, “Yes, please.”
I say Steve’s a celebrity because of the prestige of CppCon—it’s where the language developers, top educators, and infrastructure tool builders hang out. For example, Steve had lunch with Matt Goldbolt. I use Goldbolt’s app all the time and didn’t realize it was a person’s name until Steve mentioned the lunch. To get some sense of CppCon, you can see Godbolt himself going full fanboy over a CppCon selfie with Laurie Kirk.
