A developer shares frustration about OpenAI Codex CLI consuming 1.5M tokens in minutes on a game project, questioning how to use AI coding tools affordably and asking for tips.

OpenAI has acquired presentation startup NextSlide, whose team will now work on ChatGPT to continue building AI products that help people create and communicate.

A user reflects on GPT-4 as the first LLM that felt useful and practical, four years after its training finished, expressing excitement for what comes next.

Sam Altman explains how massive inference demand will finance OpenAI's frontier model training without requiring high margins, and predicts intelligence becoming fungible with advantage shifting to the largest cheapest compute fleets.

Elon Musk reacts to a report that OpenAI HR cited a security warning memo as a major reason for firing Leopold, highlighting ongoing concerns about OpenAI's security practices.

Greg Brockman notes that GPT-4 finished training four years ago today, reflecting on the milestone.

Simon Willison analyzes the timeline of OpenAI's accidental attack on Hugging Face, suggesting that RLVR training of a new model explains the lack of safety behaviors and lax monitoring.

OpenAI has flagged a possible critical cybersecurity risk in an upcoming model and is tightening controls in response.

The user found that Codex's auto-review mode calls an independent agent for approval, causing fast token consumption, and is planning to switch to full-access mode.

Greg Brockman announces ChatGPT updates, including rich formatting in the web composer and a new GPT-5.6 model for paid users.

A report on 37 former OpenAI and Anthropic employees who left to launch their own AI startups in 2026, spanning areas like automated research, AI alignment, personal AI, and agentic automation.

A detailed timeline of the OpenAI accidental attack against Hugging Face, based on a Black Hat presentation, showing how OpenAI's AI agents inadvertently compromised Hugging Face infrastructure through a series of exploits.

Sam Altman announces that 'astra' is a powerful AI model being prepared for general availability, with additional safety time needed due to its cyber capabilities.

Sam Altman announces that the Astra model is powerful and OpenAI is working to make it generally available, while taking extra time to ensure safety given its cyber capabilities.

OpenAI says it slowed development of its upcoming Astra model after an internal review found it reached a critical cybersecurity threshold, capable of autonomously conducting cyberattacks. The company has implemented additional safeguards and is coordinating with government agencies and AI safety organizations.

Greg Brockman shares a testimonial from Grigori Karapetyan praising GPT-5.6 Sol (Codex) for enabling speedy cybersafety investigations and responses.

OpenAI's next major model, Astra, shows significant capability gains in agentic coding and cybersecurity, and is being treated as a 'critical' model for cybersecurity under the Preparedness Framework, with additional controls planned.

Reports indicate that the release of GPT-6 has been delayed due to critical cybersecurity capabilities, though details are scarce.

Gergely Orosz criticizes Gartner's AI reports as pay-to-play, noting that AWS and Microsoft pay for favorable rankings while Anthropic, OpenAI, and Cursor do not, leading to skewed results like AWS being ranked above Anthropic and OpenAI omitted.

OpenAI's new model Astra is rumored to have made a breakthrough in coding ability, but because its capabilities are too strong and may pose cyberattack risks, its release has been postponed.
