OpenAI is integrating both C2PA Content Credentials and Google SynthID invisible watermarks into images generated by ChatGPT, Codex, and the OpenAI API. The dual-layer approach provides mutual redundancy — C2PA carries detailed metadata while SynthID survives image transformations. A public Verify tool is now available in preview for checking AI image provenance.
OpenAI says a general-purpose reasoning model found a construction disproving the conjectured upper bound in Erdős's planar unit-distance problem. Mathematicians reviewed the proof, but the ML community raises questions about methodological transparency.
OpenAI launched a personal finance preview for ChatGPT Pro users in the US on May 15, powered by Plaid to connect over 12,000 financial institutions. Users get a live dashboard of spending, investments, and subscriptions analyzed by GPT-5.5.
An OpenAI general-purpose reasoning model has independently solved the planar unit distance problem — a famous open geometry question posed by Paul Erdős in 1946. External mathematicians verified the proof, marking the first time AI has autonomously solved a major open problem in mathematics.
An OpenAI general-purpose reasoning model independently disproved the Erdős unit distance conjecture — a central problem in discrete geometry open since 1946. This marks the first time in history that an AI has autonomously solved a prominent open math problem, verified by independent mathematicians including Princeton's Noga Alon.
Elon Musk's lawsuit against OpenAI and Sam Altman ended in a complete defeat after a 3-week trial. The court ruled that OpenAI's transition to a for-profit structure does not violate its original charitable mission.
OpenAI and Dell Technologies announced a partnership on May 18 to bring Codex to hybrid and on-premises enterprise environments via the Dell AI Data Platform and AI Factory. The deal targets regulated industries — finance, healthcare, government — where data cannot leave private infrastructure. Codex currently serves over 4 million developers per week.
OpenAI co-founder and former Tesla AI director Andrej Karpathy announced on May 19 that he has joined Anthropic's pre-training team, where he will build a sub-team using Claude to accelerate core model training research.
OpenAI launched Codex in the ChatGPT iOS and Android app, turning phones into a remote control for Codex sessions running on a desktop or devbox. The preview rolls out across all plans including Free, with 4 million weekly Codex users.
OpenAI has launched a personal finance preview for ChatGPT Pro users in the US. By connecting bank accounts via Plaid, users receive a spending dashboard and AI-driven financial advice based on their actual transaction data.
OpenAI's new EU Cyber Action Plan grants vetted European cybersecurity teams access to GPT-5.5-Cyber, a defensive variant of its latest model tuned for vulnerability research and malware analysis. Anthropic continues to restrict its more powerful Mythos model over exploitation concerns.
OpenAI announced that Codex, its AI coding agent, is coming to the ChatGPT mobile app, enabling users to write, edit, and debug code directly from their smartphones.
