Investment firms aren't known to advertise or resell their secret sauce. AI has been used in trading in some form or the other for close to 40 years now.
What do you mean by front office trade tools? neural networks, predictive models and fancy pants math has been used in trading stocks for 40 years. That's what the Medallion Fund is based on and it generates bonkers returns.
I feel that what was missing is exactly AI front office trade tools. The trading pros who wanted a black box investing style, i.e: the math says buy stock X so buy stock X, have had the option to do that with the knowledge that it's extremely effective based on the Medallion Fund returns. That's compared to a more traditional Warren Buffet-like style of valuing a business or even a more Michael Burry-like style of finding missed gaps for a collapse.
What was missing all these years is what this is. A way for someone who doesn't know much about investing (or doesn't have the time) to "just past data there and ask it is this a good investment" like other esteemed HN members mentioned they are doing.
> Using Vcaml and Ecaml, they wired AI tools straight into Neovim, Emacs, and VS Code.. RL Feedback: The system learns from what works, tweaking itself based on real outcomes.. Jane Street records the [developer] journey — every tweak, every build, every “aha!” moment. Every few seconds, a snapshot locks in the state of play. If a build fails, they know where it went south; if it succeeds, they see what clicked. Then, LLMs step in, auto-generating detailed notes on what changed and why. It’s like having a scribe for every coder.
