OpenAI has engineered a sophisticated access management system that blends rate limits, granular usage tracking, and credit allocation to ensure continuous availability of its high-demand AI models, including Sora and Codex. This architecture is crucial for democratizing access while preventing resource exhaustion and maintaining service quality. The innovative system provides a blueprint for managing access to computationally expensive AI tools.

A new era of coding assistance is dawning! GPT-5.3-Codex-Spark, a real-time coding model boasting 15x faster generation speeds and a massive 128k context window, has landed in research preview for ChatGPT Pro subscribers. This breakthrough promises to transform the development workflow, offering unprecedented speed and understanding for complex coding tasks.

Imagine an AI that speaks with your unique vocal style. Ghostype, a novel AI voice interface, promises to learn and replicate your individual speech patterns, opening up new possibilities for personalized digital communication and content creation.

The rise of AI agents is upon us, and a critical factor in their success is how effectively we can 'harness' the power of large language models (LLMs) like Codex. A new approach, termed 'harness engineering,' focuses on optimizing prompts and environments to unlock the full potential of these models, leading to more robust and capable AI agents. This could redefine software development and automation as we know it.

The Department of Defense is taking a leap into the future of artificial intelligence with the deployment of a customized ChatGPT instance on its GenAI.mil platform. This secure and safety-conscious AI tool, developed in partnership with OpenAI for Government, aims to revolutionize defense operations and enhance decision-making capabilities within U.S. defense teams.

OpenAI has initiated testing of advertisements within ChatGPT, signaling a potential shift in the AI landscape. This move aims to support the continued availability of the free version of the popular AI tool, but promises clear labeling, ad independence from answers, robust privacy safeguards, and user control over the advertising experience.

OpenAI shares its approach to AI localization, showing how globally shared frontier models can be adapted to local languages, laws, and cultures without compromising safety.

A groundbreaking collaboration between OpenAI and Ginkgo Bioworks has yielded a dramatic breakthrough in biotechnology. By integrating GPT-5 with cloud-based automation, researchers have achieved a 40% reduction in the cost of cell-free protein synthesis, paving the way for faster and cheaper drug discovery and biomanufacturing.
