Making Trades in Microseconds and Nanoseconds
Dwarkesh Patel, Ron Minsky, Dan Pontecorvo
The event analyzes how trading systems segment operations across ultra-low, mid-range, and long-duration latency horizons to align decision complexity with hardware capabilities. It highlights the critical trade-off between intelligence and speed, demonstrating that sub-100-nanosecond regimes require FPGA-based simple logic while longer intervals support sophisticated models. The discussion concludes by outlining how competitive positioning relies on an ensemble approach that tailors decision-making processes to specific latency buckets.

The Network as a Program with Nate Foster
Nate Foster, a professor at EPFL and visiting researcher at Jane Street, bridges programming languages and networking by advocating for treating networks as verifiable programs through formal methods and Domain Specific Languages like Netcat and P4. His work has evolved from foundational theories on bidirectional data conversion to practical industrial applications, including the Butane system which compiles high-level latency policies into safe, distributed BGP configurations to replace error-prone manual router management. Foster's approach combines algebraic analysis of routing semantics with a software engineering culture that prioritizes rigorous testing and visualization, enabling complex network modifications while challenging traditional end-to-end principles in favor of in-network computing for specialized workloads.

Dwarkesh Goes Inside Jane Street's Latest AI Data Center
Dwarkesh, Ron Minsky, Daniel Pontecorvo, Mark Mirchandani
Jane Street transformed a Texas data center into a high-density liquid-cooled facility housing 4,032 GPUs to execute large language model training and custom trading architectures. The retrofit replaces legacy air-cooling with an 18°C fluid distribution system that manages 140 kW per cabinet while utilizing proprietary software to dynamically redistribute power and prevent breaker trips during peak loads. Engineering safeguards now focus on mitigating new liquid-cooling risks like biological growth and leaks, enabling sub-100-nanosecond latency required for modern algorithmic trading compared to the millisecond scales of its historical "Hive" cluster.

Why ML Needs a New Programming Language with Chris Lattner
Former LLVM creator Chris Lattner founded Modular to solve the AI industry's fragmentation by introducing Mojo, a Python-compatible language designed to unify performance and portability across competing hardware vendors. The company generates revenue through enterprise infrastructure solutions rather than licensing the language itself, aiming to replace complex C++ and CUDA workflows with a single release train supporting both NVIDIA and AMD accelerators. This approach seeks to democratize high-performance computing by providing a neutral software foundation that allows developers to build portable AI models without sacrificing hardware efficiency.

Building Tools for Traders with Ian Henry
Ian Henry, Ron Minsky, Mark Mandelbaum, Mark Mirchandani, David Eastman, Brian Dorsey
Ian Henry, a Jane Street engineer who transitioned from general web development to options trading tools, leverages the firm's custom OCaml ecosystem to build high-density interfaces that eliminate mouse usage and manage complex volatility surfaces. His recent work includes creating Bauble, a live 3D graphics environment in the Janet language that demonstrates how side projects using image-based state serialization and novel macro systems can rapidly inform internal production tooling. Through this process, Henry illustrates how Jane Street bridges the gap between low-latency exchange architecture and expert user needs by prioritizing type safety, extreme information density, and a parallel software universe free from standard web protocols.

Finding Signal in the Noise: Machine Learning and the Markets with In Young Cho
Inyoung Cho details her transition from biology to Jane Street, where she now leads machine learning initiatives that leverage thousands of GPUs and terabytes of daily market data to navigate the anti-inductive nature of financial signals. Her presentation contrasts the firm's direct client trading model, which mitigates market impact through human interaction, with modern research pipelines that prioritize data discipline over model interpretability to prevent overfitting in high-frequency environments. Looking forward, Cho outlines how Jane Street is applying deep learning and foundation models to extract signals from multimodal data while refining internal tools through structured training that balances rapid exploration with robust production systems.
