OpenAI has announced its AI model has produced solutions for 377 open mathematics problems. [^2] This is a large increase from the 100 problems the company originally claimed in September.

Leaders of Meta, Nvidia, Google, Anthropic, xAI, and OpenAI have signed the AI Accords, an agreement asking participating companies to implement internal controls and monitor model alignment. [^1]

OpenAI Group PBC and Anthropic PBC collectively raised over $200 billion in the first half of 2026. That sum accounted for the majority of total venture deal value over the period. [^3]

The EU AI Act transparency regulations entered into force on August 2, 2026. Both OpenAI and Anthropic are adapting operations to meet these rules. [^4]
