Meta paper ranks frontier agents by learning efficiency per dollar

The best single-game performer was not the most efficient learner, so one-shot benchmark scores can mislead when choosing an agent for long-horizon work. Teams building self-improving systems should track held-out learning curves against compute cost and verify that saved tools and notes are actually reused. The frozen-weights design makes the results directly relevant to anyone running agents under a fixed budget.

Paper Instruments releases Ultramarine 1 Flash for document workloads

A cost gap of roughly 60x per task against Claude Fable 5, while scoring higher on a deliverables benchmark, could push professional-services firms to re-evaluate which workloads run on open models. Builders fine-tuning on top of GLM-5.3 Flash now have a concrete vertical example of post-training for rubric-graded outputs. Its open weights also make on-premise deployment viable for firms with client confidentiality constraints.
