How long is Anthropic's lease with SpaceX? Opinions vary (3 minute read)
SpaceX earlier this month signed a major compute deal with Anthropic worth billions of dollars a month. However, Elon Musk recently downplayed the deal, saying that SpaceX had not committed to leasing its compute for years, even though it is possible that might happen. The agreement is actually a 180-day lease with a 90-day mutual cancellation thereafter. The short-term agreement was SpaceX's request as it may want the compute back at some point. Musk's statement directly contradicts SpaceX's S-1 filing, which presents the deal as a three-year agreement.

Agent Judge: Solving Long-Context Evals for Production Agents (10 minute read)
Agent Judge improves evaluations for long-context, production agents by focusing on Search, Verification, and Adaptation. It tackles LLM judges' shortcomings by navigating long trajectories, verifying stateful actions against systems, and updating rubrics based on real feedback. Test results show Agent Judge, especially with refined rubrics, surpasses traditional LLM judges in accuracy and consistency, particularly in challenging scenarios.

How far behind are open models? (17 minute read)
Open models are generally not as capable as the best closed models. However, they aren't too far behind, with tests showing that they are only four to six months behind on public benchmarks. The gap was the smallest around the time of DeepSeek R1. It has since been growing.

Data Isn't Scarce. Your Imagination Is (8 minute read)
Asuka Zheng argues the "we're running out of training data" panic misses the actual shape of the data market, recounting her own SRE-replacement project that trained two world models until it stalled because end-to-end long-horizon incident trajectories from first anomaly to full resolution did not exist as a dataset.
