Researchers find Grok Build exposes data from over 35,000 apps
Researchers found that Grok Build, SpaceXSI's AI coding agent, is leaking data from over 35,000 apps through shareable links, Ars Technica reported. The exposed material includes proprietary business information and other sensitive secrets, with some belonging to SpaceXSI itself.
MOAI preprint reports 52.8% reduction in encrypted transformer evaluation time
Researchers propose MOAI, a framework for running transformer models on encrypted inputs, and report a 52.8% reduction in evaluation time compared with THOR, an existing non-interactive encrypted inference system.
Medical AI training reduces false lesion reports but misses critical external cases
Researchers report in a preprint that training MedScope-4B on images with lesions erased reduced its tendency to report findings absent from an image.
Plumbline preprint reports 61 training problems found across five AI models
Researchers report that Plumbline, a system used in production at Amazon to validate large language model training, found 61 problems across three frameworks and five models. Of those problems, 32 were silent failures.
TimeOmni-o1 combines text reasoning and time series forecasting in one architecture
Researchers report that TimeOmni-o1 combines a language model with a pretrained time series model to interpret text and numerical sequences together and generate both text and forecasts.
Tree-Ising preprint reports cheaper weight repairs that improve math accuracy
Researchers report in a preprint that Tree-Ising repairs language model weights with four forward-pass requests and zero LLM tokens. On Qwen3.5-0.8B, the method scored 54.6% on MATH-500, compared with 51.7% for an earlier agent-generated repair under the same evaluation protocol.
