1. ARC-AGI-3 Scores Surge from 7% to 56% in 30 Days

A Reddit report says top ARC-AGI-3 Kaggle scores rose from 7% to 56% in a month, with small local models in harnesses reportedly beating average humans on the benchmark. ARC-AGI was designed to resist memorization and test fluid reasoning, so rapid gains suggest agent harnesses and test-time compute are shifting the frontier. The leaderboard graphic is noted as slightly out-of-date, so treat the jump as directional but still significant. Source-reddit

2. SWE-Race Benchmark Puts Coding Agents on Real Concurrency Bugs

SWE-Race introduces 188 concurrency bugs from merged PRs across about 100 Python projects, graded by each project’s own tests in an offline container. Initial results put GLM-5.3 Flash at 85% on one attempt, but hard-task scores fall to 50%, 45%, and 23%, exposing sharp reliability gaps. The leaderboard now reports attempts and confidence intervals, making agent evaluation more honest. Source-reddit

3. Self-Generated Feedback Destabilizes Test-Time Training

New research shows test-time training on generated output creates a feedback loop that degrades predictions on independent human-written text across 125M, 760M, and 3B TTT-E2E models. The same failure occurs when Adam updates Qwen3-4B’s existing weights, suggesting weight-based adaptation can overfit self-generated artifacts. This is a caution for long-horizon agents and continual-learning systems that rely on self-training. Source-huggingface
