OpenAI is reportedly preparing to confidentially file IPO paperwork with the SEC as early as May 22, teaming up with Goldman Sachs and Morgan Stanley. Valued at over $850 billion in private markets, the AI pioneer could go public as soon as Q4. If completed, it will be one of the biggest listings in tech history.
OpenAI just revealed that an internal general-purpose reasoning model autonomously disproved the planar unit distance conjecture, first posed by Paul Erdős in 1946. By applying sophisticated tools from algebraic number theory to discrete geometry, the model overturned a decades-old belief about grid constructions. Fields medalist Tim Gowers and other mathematicians verified the proof, marking a massive leap for AI in scientific discovery.
OpenAI just launched Reserved Tier for enterprise API customers, letting teams pre-purchase model throughput denominated in dollars per minute. The reservation secures dedicated capacity during peak traffic across Standard and Fast modes without running into rate limits. Usage beyond your reserved ceiling reverts to standard pay-as-you-go rates, while Batch and Flex modes remain unsupported.
AI heavyweight Andrej Karpathy has joined Anthropic to get back into frontier LLM research and development. The former OpenAI co-founder and Tesla AI lead noted that the next few years will be especially formative for language models, though he plans to resume his education efforts down the road. It is a massive talent win for Anthropic as the frontier lab race tightens.
OpenAI just teamed up with Google DeepMind to embed invisible SynthID watermarks across images from ChatGPT, Codex, and its API. It also rolled out a public verification portal that cross-checks C2PA credentials and watermarking signals. Why it matters: combining metadata with resilient invisible watermarks makes AI media far harder to forge or launder.
Elon Musk just lost his high-stakes lawsuit against OpenAI CEO Sam Altman and Microsoft, with a federal jury unanimously throwing out all claims after only two hours. The jury ruled Musk's breach of trust claims were barred by the statute of limitations, which the judge accepted. Musk dismissed the verdict as a calendar technicality and plans to appeal.
OpenAI just partnered with Dell Technologies to bring Codex to hybrid and on-premises enterprise environments. By plugging directly into Dell AI Data Platform and Dell AI Factory, companies can build and run AI agents right next to their governed internal data. Why it matters: it clears a major regulatory hurdle for enterprises wanting frontier coding agents without sending proprietary data to the cloud.
OpenAI just partnered with the Government of Malta to roll out free ChatGPT Plus to all citizens for a year. The only requirement is completing a free AI literacy course developed by the University of Malta to learn how to use the tech safely. Why it matters: It is the first nationwide rollout under the OpenAI for Countries initiative, moving closer to the vision of intelligence as a universal public utility.
OpenAI just rolled out personal finance tools inside ChatGPT, letting U.S. users securely connect accounts from over 12,000 financial institutions via Plaid. Powered by GPT-5.5 reasoning, the tool creates spending dashboards, stores financial memories across chats, and answers questions grounded in real account balances. Why it matters: ChatGPT is evolving from generic financial advice into an active, context-aware money manager.
A California resident just filed a class-action lawsuit against OpenAI, alleging the company embedded Meta's Pixel and Google Analytics into the ChatGPT web interface. The suit claims these integrations sent user queries directly into commercial ad ecosystems. Why it matters: It puts a harsh legal spotlight on how AI companies handle user telemetry and privacy behind the scenes.
OpenAI just rolled out Codex inside the ChatGPT mobile app in preview across iOS and Android for all plans. Developers can now steer long-running coding tasks, approve terminal commands, and inspect diffs directly from their phones without staying glued to their desks. Secure relays keep local setups safe while syncing context in real time.
Gemini 3.2 Flash reportedly hits 92% of GPT-5.5's coding and reasoning performance while running 15 to 20 times cheaper on inference. Powered by DeepMind's distillation and sparsity techniques, it also reportedly pushes response times below 200ms. If true, developers may get near-frontier capability without the frontier price tag.
Anthropic just dethroned OpenAI in enterprise adoption, capturing 34.4% of businesses compared to OpenAI's 32.3%, according to fintech platform Ramp. Anthropic's business share quadrupled over the past year by focusing on technical teams first. Why it matters: OpenAI's enterprise moat is visibly cracking, though Anthropic now faces rising costs and reliability growing pains.
OpenAI just confirmed two employee laptops were compromised in a TanStack npm supply chain attack, exfiltrating app code-signing certificates. While user data and production systems were untouched, Mac users must update ChatGPT Desktop and companion apps before June 26, 2026, to prevent macOS from blocking them once old certificates are revoked.
OpenAI just detailed how it built a custom Windows sandbox for its Codex coding agent to solve a major usability headache. Without native OS isolation like macOS or Linux offer, the team used synthetic SIDs and write-restricted tokens to lock down file writes and network access without requiring admin privileges. Why it matters: Windows developers no longer have to pick between approving every command or blindly giving the agent full machine access.
OpenAI just launched Daybreak, a cybersecurity initiative pairing frontier models with its Codex agentic platform to discover, validate, and patch software flaws. The company is putting up $1 billion in credits over six months for defenders and open-source maintainers, using tiered access to keep advanced capabilities under human oversight.
OpenAI just launched the OpenAI Deployment Company, a standalone unit backed by over $4 billion in initial investment from 19 partners, to help enterprises build durable AI systems. It is also acquiring AI consultancy Tomoro to bring 150 Forward Deployed Engineers into client offices. It is basically Palantir's playbook applied to frontier LLMs.
OpenAI just brought its Codex agent directly into Chrome on macOS and Windows. The agent can now juggle background tasks across multiple tabs at once without taking over your active browsing session, while interacting much more smoothly with web apps. It's a major leap toward seamless, non-intrusive browser automation.
Microsoft just added OpenAI's GPT-5.5 Instant to Microsoft 365 Copilot and Copilot Studio. The new model cuts down on verbosity, delivers faster and clearer answers for daily workflows, and sharpens image analysis and STEM tasks, with priority access for licensed users.
OpenAI just launched GPT-5.5-Cyber in limited preview for critical infrastructure defenders, alongside its Trusted Access for Cyber program. Vetted security researchers get fewer classifier refusals to run authorized penetration tests and red teaming without guardrails getting in the way. It is built to level the playing field against attackers, though users must adopt phishing-resistant authentication by June 1, 2026.
