    Here is where things have split:

    Recent geopolitical events and trade tensions are reshaping the semiconductor supply chain, particularly for photoresist materials. Korean companies are increasing reliance on domestic suppliers and have secured waivers to import Russian naphtha, while Japanese firms, adhering to G7 restrictions, face disruptions due to their just-in-time inventory models. This divergence creates opportunities for Korean suppliers and risks for Japanese ones in the critical photoresist production process. AI

    IMPACT Shifts in photoresist supply chain due to geopolitical tensions could impact semiconductor manufacturing capacity and costs.

    RL²: Fast reinforcement learning via slow reinforcement learning

    OpenAI has published a series of research papers detailing advancements in reinforcement learning (RL). These include achieving superhuman performance in the game Dota 2 using large-scale deep RL, developing benchmarks for safe exploration in RL environments, and quantifying generalization capabilities with a new environment called CoinRun. The research also explores novel methods like Random Network Distillation for curiosity-driven exploration, Evolved Policy Gradients for faster learning on new tasks, and variance reduction techniques for policy gradients. Additionally, OpenAI is investigating policy representations in multiagent systems and the theoretical equivalence between policy gradients and soft Q-learning. AI

    Anthropic conducted an experiment where Claude agents acted as digital barterers, successfully negotiating 186 deals totaling over $4,000. Participants found the deals fair, with nearly half expressing willingness to pay for such a service. The experiment highlighted that while model quality, such as Opus versus Haiku, significantly impacted deal outcomes, human participants did not perceive this difference. AI
