ChatGPT's market share falls below 50% amid AI assistant competition

OpenAI research scientist Noam Brown stated that the company's top priority when training new AI models is automating AI research and development, describing recursive self-improvement as the number one goal by a wide margin. While GPT-6 Astra showed improvements across professional tasks including video game design and sheet music transcription, Brown emphasized that these capabilities are secondary to the core objective of enabling AI to improve itself. Brown, who has spent three years at OpenAI focusing on AI reasoning and autonomous agents, discussed these priorities in an interview for The Information's new AI Deep Dive series.

Fyxer, an AI executive assistant built on OpenAI models, uses fine-tuning, memory systems, and user feedback to automate email management and draft messages in each user's personal voice. The product demonstrates how combining model capabilities with personalization and iterative feedback can build user trust in AI-assisted productivity tools. Fyxer organizes inboxes and generates email drafts tailored to individual communication styles.

OpenAI has acquired Glass Imaging, a smartphone camera technology company, for $300 million according to reports. Glass Imaging was founded by two former Apple engineers who led development of Apple's Portrait Mode. The acquisition signals OpenAI's expansion into hardware and camera technology, potentially to support multimodal AI capabilities.

Major defense and technology contractors including Palantir, Nvidia, and Booz Allen Hamilton are restricting or eliminating their use of advanced AI models from Anthropic and OpenAI due to concerns that the AI firms could access their proprietary data during model training or operation. The moves reflect growing corporate anxiety about intellectual property protection when using third-party AI systems. These restrictions signal a potential friction point between enterprise adoption of frontier AI models and data security requirements in sensitive industries.
