UnverifiedDecision models experienced a concentrated explosion between 2024 and 2025, due in part to the popularization of agent orchestration frameworks (such as LangGraph and AutoGen) making 'decision nodes' a system bottleneck, and enterprise deployment needs driving the search for more economical alternatives to full-scale LLMs.65% similarUnverifiedBetween 2024 and 2025, reasoning models and general-purpose models were clearly two product lines, but by 2026 mainstream flagship models had basically all shifted to a unified architecture plus adaptive reasoning.65% similarUnverifiedIn AQuA's U.S. stock market experiment, the model was trained on data from 2010–2019, with 2020 set as an embargo zone and 2021–2025 used as the final test window.65% similarUnverifiedIn the second year after 2024, models from multiple institutions were able to solve all IMO problems except the last one.64% similarUnverifiedThe systems in the paper used 2024-25 models, whereas this test used a 2026 model (Claude Sonnet 5.5), so part of the performance gap comes from capability improvements in the model itself.64% similar
