OpenAI is launching GPT-5.5-Cyber, a specialized cybersecurity model that will not be available to the general public. Instead, the model will roll out first to a vetted group of 'cyber defenders' and institutions to strengthen their defensive capabilities. CEO Sam Altman announced the limited rollout will begin within days, with access determined through collaboration between OpenAI, the broader security ecosystem, and government partners. The exact criteria for initial access remain unclear, though OpenAI's previous trusted access programs have prioritized vetted professionals and institutions.

DeepSeek, a Chinese AI company, released a preview of its V4 model on Friday, claiming it can compete with leading closed-source systems from Anthropic, Google, and OpenAI. The model shows significant improvements in coding capabilities, a key differentiator for AI agents and tools like ChatGPT Codex and Claude Code. The release also marks progress for China's domestic chip industry, with DeepSeek emphasizing compatibility with Huawei technology. This announcement comes roughly a year after DeepSeek's previous release rattled US AI competitors.
