⚡ BREAKTHROUGH

Nvidia's AVO agent solves ARC-AGI benchmark

2x SOURCES 🌐 📅 2026-08-21

⚡ Score: 8.9

+++ Nvidia's AVO agent swept ARC-AGI-3's benchmark, but the real breakthrough wasn't the model itself—it was the engineering harness that knew exactly how to talk to it, a reminder that orchestration now beats raw capability. +++

Nvidia says its general-purpose coding agent system AVO scored 100% across all 25 environments in the ARC-AGI-3 public set, completing all 183 levels

Phantom Gains: Auditing Self-Improvement Against a Measured Null

via Arxiv 👤 Cheng Xu, Nan Yan, Liming Chen et al. 📅 2026-08-20

⚡ Score: 6.9

"Whether a language model has improved itself is increasingly judged not by mean accuracy but by which individual problems it gains and loses. Tracking these transitions means differencing two noisy estimates, leaving them vulnerable to measurement artifacts. Auditing three rounds of rank-$32$ LoRA s..."
