AI Benchmark Debate: xAI vs. OpenAI

A debate has erupted concerning AI benchmarks after an OpenAI employee accused Elon Musk's xAI of publishing misleading benchmark results for its Grok3 model. The controversy revolves around xAI's graph showcasing Grok3's performance on the AIME 2025 math question set, where it seemingly outperformed OpenAI's o3-mini-high model. However, xAI's graph omitted o3-mini-high's score at "cons@64," a method that significantly improves benchmark scores. xAI defends its methods, claiming OpenAI has also presented misleading charts in the past. Despite the debate, xAI is advertising Grok3 as the "world's smartest AI."

Technology & Policy

Potential Layoffs at NIST Impacting AI Safety

The National Institute of Standards and Technology (NIST) is planning potential layoffs of up to 500 staffers, which could significantly impact the AI Safety Institute (AISI) and Chips for America. These layoffs, primarily targeting probationary employees, have raised concerns about the future of AISI, especially after the director's departure in February. The institute's future appears uncertain, particularly with the current administration potentially repealing the executive order that established it. Experts warn that these cuts could severely undermine the government's ability to address critical AI safety concerns.

Artificial Intelligence Advancements

AI Browser Agents

• A new wave of AI-powered browser-use agents is emerging, including OpenAI's Operator and Convergence's Proxy. These agents autonomously navigate websites, retrieve information, and complete transactions. The key is to find suitable developer and enterprise use cases, possibly in combination with tools like Deep Research.

Google DeepMind's Mixture-of-Depths (MoD) Transformers

• Google DeepMind is implementing Mixture-of-Depths (MoD) Transformers, which leverage conditional computation to determine when and how to expend computation. In MoD, a token can skip middle layers and later be updated via self-attention.
• This method sets a static compute budget by limiting the number of tokens in a sequence that can participate in a block’s computations, using a per-block router to emit a scalar weight for each token, which expresses the router’s preference for that token to participate in a block’s computations or to route around it.
• MoD transformers drag the baseline isoFLOP curve "down and to the right". The optimal MoD transformer achieves a lower loss than the optimal baseline and also has more parameters, outperforming the isoFLOP optimal baseline (also 220M), but is upward of 60% faster to step during training.
• MoD transformers improve on isoFLOP-optimal baseline performance with models that use fewer FLOPs per forward pass. Learned routing mechanisms are sometimes non-causal, using information about the future to determine a given token’s routing decision.

OCEAN: A Decentralized AI Assistant

• O.XYZ has launched OCEAN, a decentralized AI assistant that is reportedly faster than ChatGPT, powered by the Cerebras CS-3 wafer-scale chips. The Cerebras CS-3 chip has 900,000 AI-optimized cores and four trillion transistors on a single chip, scaling from one billion to 24 trillion parameters without code changes, with 21PB/s of memory bandwidth. OCEAN adopts a dual approach, serving both individual consumers and enterprises with a voice interaction system and advanced AI agent capabilities.
