A task factory ran fifteen rounds and broke the model grading it News
A new paper builds harder and harder terminal tasks by recursively rewriting accepted ones, and across fifteen rounds a fixed frontier solver's success rate fell from 90 percent to 2.5 percent, with the authors reporting no ceiling in sight.
Synthetic Data: When AI Makes Its Own Training Material Lesson
The internet is running out of fresh text to train on, so the most advanced models increasingly learn from data that other AI made or shaped. Here is how that works, why it helps, and how it can quietly poison a model.
Recursive-Task-Synthesis Tool
A public set of 37,484 verified long-horizon terminal-agent tasks, each a runnable bundle with instruction, environment, reference solution and hidden verifier, plus a companion set of 327,000 agent trajectories and three fine-tuned Qwen3.5 checkpoints.
