Ai2

A new robotics benchmark called StationeryBench shows OpenAI's GPT-6 Astra completing 7 of 100 desk-object manipulation tasks versus zero for Ai2's MolmoAct2, with a median progress score of 46 against 12. Cornell/DeepMind researcher Yoav Artzi calls the result a 'step change in spatial reasoning.'

Ai2 has released BenchMIRT, a technique that uses multidimensional item response theory to analyze which underlying capabilities drive scores on individual benchmark questions. Trained on 100 LLMs across 16 benchmarks and 34,000+ questions, it found that benchmarks like BBQ and WMDP measure general reasoning more than safety, despite being marketed as safety evaluations.

Ai2's new TutorMoments framework replays real tutoring transcripts to test whether LLMs make the right pedagogical call at key decision points. Across seven models tested, all defaulted to over-helping unless explicitly prompted about the scaffolding-versus-rigor trade-off.

Ai2 has launched the OlmoEarth Platform, infrastructure built to run its OlmoEarth Earth observation foundation models at continent scale. A North America wildfire-risk map used nearly 20,000 CPUs and 994 GPUs simultaneously, cutting an estimated 4,737 serial-compute hours to about 30.5 hours.
