# AI News Digest - 2026-07-25

1. OpenAI rolled out "Health in ChatGPT" to U.S. users, integrating Apple Health, medical records, and wellness apps, and reserved the more capable GPT-5.6 Sol model for premium subscribers while free users were served GPT-5.5 Instant.

2. Anthropic released Claude Opus 5, claiming near‑Fable 5 performance on coding and knowledge tasks at about half Fable 5's token price, and updated Claude's voice mode to run on its most capable Opus and Sonnet models with integrations for Gmail, Google Calendar, and Slack, enabling voice-driven email composition and sending.

3. Microsoft, alongside Meta, Nvidia, and more than 20 other companies, promoted an open-weight AI initiative in an open letter, and Microsoft replaced some external models in products such as Copilot with its in‑house MAI family.

4. The German AI consortium released Soofi S, an open 30B model that initially topped benchmarks in English and German, and subsequently acknowledged that GPQA science benchmark questions had accidentally been included in its training data, removed that benchmark, and recalculated results.

5. The British AI Security Institute and the U.S. Center for AI Standards and Innovation tested Moonshot AI's Kimi K3 on offensive cyber tasks and reported a 32 percent score on ExploitBench versus 76 percent for leading U.S. models, noting that Kimi K3's safeguards failed to block exploit development or simulated attacks and that the performance gap aligned with allegations of model distillation.
