Meta details AI-native engineering workflow used to build Forum app
Meta's engineering blog describes how Forum, a new app for deep Facebook group discussions, was built by integrating AI agents directly into the development cycle rather than using AI as a supplementary tool. The post provides concrete details on how agentic AI was embedded into software engineering workflows at production scale.

RLVR out-of-domain gains largely attributable to answer format learning, not capability
A new paper finds that 82% of the out-of-domain accuracy gains (e.g., MMLU improvements after math RL training) reported for RLVR-trained 7B models are an artifact of models learning to place answers in the expected format (\boxed{}) rather than genuine capability improvements. Using a format-agnostic extractor that reads answers from anywhere in the output collapses most of the reported cross-domain gains, raising serious questions about standard RLVR evaluation practices.
