A researcher's 10-page domain-expert prompt helped GPT-5.6 produce a Lean-verified proof closing a complexity gap that stood since 1996. The paper is now on arXiv.
OpenAI crossed 8 million active users on Codex and ChatGPT Work in one week. Here is what drove the surge, what changed for developers, and what to watch as capacity scales.
OpenAI's Codex CLI now encrypts inter-agent communications for Sol and Terra models, leaving users unable to inspect what their agents are actually doing.
Apple filed suit against OpenAI alleging systematic theft of hardware trade secrets by former employees. The complaint names specific individuals, describes exploited security vulnerabilities, and claims this is 'the tip of the iceberg.'
OpenAI claims GPT-5.6 Sol Ultra has generated a proof for a 50-year-old graph theory conjecture in under an hour. The math community is now verifying whether it holds up.
OpenAI is consolidating its desktop apps, not merging ChatGPT and Codex into one indistinguishable product. Here is how ChatGPT Work, Codex, and GPT-5.6 fit together.
A practical guide to choosing GPT-5.6 Sol, Terra, and Luna, using programmatic tool calling, caching, and the multi-agent beta in production.
OpenAI teases its most capable coding model yet - Sol Ultra uses trained subagents that communicate during tasks, reportedly hitting 91.9% on Terminal-Bench 2.1.
GPT-5.6 Sol dropped on June 26, 2026 as a limited preview with government-imposed access restrictions. Here is what developers need to know about the three-tier Sol/Terra/Luna model family, pricing, availability timeline, and how to prepare your codebase for GA.
OpenAI's workplace agent data points to a practical shift: non-developers are starting to use agents for real work, so engineering teams need paved paths, policy, and receipts.
A companion guide to the Codex Record & Replay video: OpenAI Codex can now record a recurring computer task and replay it as a reusable automation skill. Here is what the feature is and where it fits.
A companion guide to the GPT-5.5 video: OpenAI's newly released model rolling out to ChatGPT and Codex, reviewed through benchmarks, agent capabilities, context window, and pricing. Here is what the video covers and where to go deeper.
A companion guide to the OpenAI Codex video: a tour of the Codex desktop app, its plan and goal modes, plugins, multi-agent workflows, and UI annotation. Here is what the video shows and where to go deeper.
