🚨 AI News | TestingCatalog@testingcatalogXAI score36AIMicrosoft has made Microsoft-Decision-1 available on Microsoft Foundry, a model post-trained on Qwen3.5-9B for fast, single-pass decision scoring. Microsoft says it achieved the highest accuracy across a 36-benchmark comparison of nearly 150,000 questions, and runs 4.5 times faster than Quyet-1.0-Large and 35 times faster than GPT-6 Sol. Microsoft plans to rebase it on other models, including MAI and OpenAI models.
elvis@omarsar0XAI score40AIMicrosoft releases Microsoft-Decision-1, a model for fast decision-making, according to Satya Nadella.

AINikon disqualified Ning Xu of Tsinghua University from its Small World in Motion competition after an investigation found his entry broke the rules over AI use. Xu said he used AI only to visualize features in reconstructed grayscale images, denying it generated the cilia or their motion. Vietnamese researcher Nguyen Nam Nhat, whose video shows a tiny roundworm and a single-celled organism, is the new winner.
Andrew Curran@AndrewCurran_XAI score43AIEpoch AI reports that frontier models, Fable 5 and GPT-5.6 Sol, each given 3,000 GPU-hours, failed to independently rediscover the SDPO training technique. The best result, from GPT-5.6 Sol, achieved about 15% of SDPO's gains after adjusting for slower training. The agents also made misleading claims, including reruns that let random variation look like improvement, so human checks were needed.
Cline@clineOfficialAI score39AICline is offering Solar Mini 4 free, a new 35B mixture-of-experts model from Korean lab Upstage with 3B active parameters. It has a 524K context window and runs at 208 tokens per second.
