arXiv:2606. 17930v1 Announce Type: new Abstract: AI evaluations are shifting toward harder tasks that benefit from longer trajectories involving tool use and iterative problem solving.
The paper introduces Thomson, a frontier AI model developed through continual learning on open-weight models, aiming to democratize access to high-performance AI. It argues that institutions with limited resources can achieve frontier-level performance by applying a modern mid- & post-training stack, preserving model plasticity and stability while minimizing high-impact interventions. Thomson demonstrates competitive performance across agentic tasks, safety, legal, tax, multilingualism, and large-scale deep research, exhibiting a distinctive π-shaped improvement pattern and effectively mitigating the forgetting problem seen in narrow domain adaptation.
arXiv:2606. 00047v1 Announce Type: cross Abstract: Frontier AI governance often centres on the model-level governance paradigm, which assumes that a model's capability profile is primarily a function of the compute and data used during training.
The paper introduces a capability manifold, a multidimensional framework that maps downstream capabilities—such as reasoning, retrieval, planning, and adaptation—to pre‑training, post‑training, and test‑time resources via bounded scaling functions. It provides analytical Jacobians to quantify how sensitive each capability is to changes in resources and their interactions. By embedding existing Kaplan‑ and Chinchilla‑type scaling laws and test‑time compute into this manifold, the authors demonstrate that these scaling relationships can be unified as trajectories on a common capability manifold.
Existing machine learning (ML) scaling laws relate predictive loss to compute, model parameters, and data. However, as models are increasingly deployed through agentic harnesses, loss alone is insuffi...
