    Guys, please fix your audio setup. The microphone noise, phones buzzing, typing on keyboards, etc. makes this hard to listen to.

Talking Points

Recent interactions between the hosts and their guests.

Ep. 026 - PJM's $12B Modeling Mistake Is Hitting Ratepayers Again (Datacenter, Energy) | Robert Boswall, Jordan Nanos
Q: What governance issues are raised by PJM's board overruling member votes, and how might that affect outcomes?
The board has overridden member votes in past decisions, which raises concerns about regulatory capture and governance legitimacy; this dynamic can push toward long-term contracts that may not align with actual demand, risking higher costs for ratepayers.
Ep. 026 - PJM's $12B Modeling Mistake Is Hitting Ratepayers Again (Datacenter, Energy) | Robert Boswall, Jordan Nanos
Q: How does winterization affect pricing and reliability in PJM?
Winterization makes plants more reliable in cold scenarios and can justify higher payments in auctions; ignoring winter performance leads to overbuying and higher costs for consumers, whereas properly rewarding winterized plants could reduce overpayments.
Ep. 026 - PJM's $12B Modeling Mistake Is Hitting Ratepayers Again (Datacenter, Energy) | Robert Boswall, Jordan Nanos
Q: What is PJM and why is it unique in its auction design?
PJM runs long-term capacity auctions across a large footprint, requiring capacity for the worst day of the year and setting a market price based on the intersection of supply and demand curves; this design creates a reliability margin but can overpay when supply is constrained or when winter conditions aren't properly modeled.
Ep. 002 - InferenceX 2.0 Release (Technical Staff) | Cam Quilici, Bryan Shan, Doug O'Laughlin, Jordan Nanos
Q: How do these optimizations translate to real-world costs and deployment?
MTP and related optimizations significantly reduce cost per million tokens and increase tokens per second per user, enabling cheaper operation and potential end-user savings, while still allowing benchmarking to reflect real-world configurations, such as multi-node setups and mixed hardware fleets.
Ep. 002 - InferenceX 2.0 Release (Technical Staff) | Cam Quilici, Bryan Shan, Doug O'Laughlin, Jordan Nanos
Q: Why is there a 2.0 release and what are the major changes from 1.0 to 2.0 moving to InferenceX?
2.0 expands beyond single-node benchmarks to include disaggregated pre-fill, wide expert parallelism, speculative decoding, and broader hardware support (GB200/GB300) with multi-node testing, aiming for a more nuanced, production-like view of frontier inference and improved throughput and cost metrics.
