OpenAI just temporarily lifted the 5-hour usage limit on Codex and ChatGPT Work for all Plus, Business, and Pro subscribers after hitting 6 million active users. The team is also rolling out efficiency updates to GPT 5.6 Sol to curb token consumption, giving heavy users significantly more runway before hitting hard caps.
Apple just sued OpenAI for trade secret theft and breach of contract, targeting its Chief Hardware Officer and 24-year Apple veteran Tang Tan. The complaint alleges Tan used confidential code names during recruiting and asked candidates to bring hardware parts to interviews. As OpenAI builds out its secretive device team, the AI battleground has spilled directly into the courtroom.
OpenAI just published a paper proving the cycle double cover conjecture, a graph theory problem unsolved for over 50 years. Powered by GPT-5.6 Sol Ultra, the model spun up 64 subagents and generated the entire proof in under an hour. Why it matters: Frontier AI is officially shifting from helping mathematicians check steps to independently cracking open problems.
OpenAI just announced it will reset rate limits twice across ChatGPT Work and Codex over the next 24 hours to celebrate the launch of GPT-5.6 Sol. The temporary boost gives users extra breathing room to test ambitious tasks and get familiar with the new model without constantly bumping into usage caps. Why it matters: If you have heavy workloads lined up, today is the day to push the new model to its limits.
OpenAI just expanded its bio bug bounty into a permanent private program and doubled the top prize for universal jailbreaks to $50,000. The challenge tasks approved red teamers with cracking biosafety guardrails on its frontier models, with partial rewards also on the table. Why it matters: as AI tackles more biological science, OpenAI is paying serious cash to stop potential biorisks before they emerge.
OpenAI just rolled out ChatGPT Work, a new autonomous agent powered by its latest GPT-5.6 model. It connects directly to workplace apps like Slack, Teams, and Google Drive, breaking down complex tasks into smaller steps that run for hours in the background. The agent can create docs, decks, and full web apps via Sites, with rollouts starting for Pro, Enterprise, and Edu users.
OpenAI just launched the GPT-5.6 family for general availability, featuring flagship Sol, balanced Terra, and low-cost Luna. Sol hits a state-of-the-art 53.6 on Agents' Last Exam, outpacing Claude Fable 5 by 13.1 points while cutting costs. It also introduces an "ultra" mode running four parallel agents to crush heavy workloads faster.
OpenAI just published an audit of SWE-Bench Pro, revealing that roughly 30% of its coding tasks suffer from serious evaluation flaws like overly strict tests and misleading prompts. After screening tasks with automated pipelines and software engineers, the lab retracted its earlier recommendation of the benchmark and called for reliable evaluations built specifically for AI models.
OpenAI just launched GPT-Live, a full-duplex voice model powering ChatGPT Voice that can speak and listen at the same time. Instead of awkward turn-taking, it responds with natural affirmations like "mhmm" and delegates complex reasoning to GPT-5.5 in the background while keeping the conversation moving. It is rolling out globally across web and mobile.
OpenAI just published its National Security Principles, outlining hard boundaries for how governments and defense agencies can deploy its models. The guidelines explicitly ban AI use for mass domestic surveillance, autonomous weapons direction, and high-stakes automated decisions, applying directly to its work with defense agencies and nine allied nations.
OpenAI just announced that three new GPT-5.6 model variants — Sol, Terra, and Luna — are officially launching publicly this Thursday. The company is already expanding preview access globally ahead of the rollout. While OpenAI hasn't shared specific specs for each variant yet, dropping all three at once signals a major push for the GPT-5.6 family.
Microsoft is quietly swapping out top-tier models from OpenAI and Anthropic across Excel and Outlook, replacing them with its own in-house MAI models to cut soaring bills. Microsoft AI chief Mustafa Suleyman said Anthropic is "extremely expensive" and aims to eliminate that spend completely. The change handles tens of thousands of weekly prompts, marking a clear pivot toward cheaper, self-reliant infrastructure.
Anthropic is reportedly in early talks with Samsung Electronics to manufacture custom AI chips, eyeing its advanced nodes and packaging. The Claude maker hasn't started detailed silicon design yet, but it already hired OpenAI chip veteran Clive Chan to chart its hardware roadmap. If finalized, the deal would give Anthropic tighter compute control while handing Samsung a marquee win against TSMC.
Microsoft just launched Frontier Company, a new business backed by a $2.5 billion investment to embed 6,000 engineering experts directly at customer sites. The initiative helps enterprises build custom AI workflows across models from OpenAI, Anthropic, and open source, while guaranteeing proprietary data is never used to train shared models.
OpenAI just floated giving the US government a 5% ownership stake to smooth over tensions with the Trump administration and dodge heavy-handed regulations. Based on the startup's latest $852B valuation, that cut is worth roughly $42.6B. Altman pitched it as a way for the public to share the upside, though talks are still in early stages.
Square just launched integrations for ChatGPT and Claude that allow U.S. restaurants to take orders directly inside AI chat interfaces. Sellers pay standard processing rates with zero marketplace commissions, and tickets sync right to existing kitchen screens. Food delivery platforms taking 30% cuts should be very nervous.
OpenAI engineers have discovered optimizations that slash AI inference costs by more than half, according to The Information. When applied to ChatGPT for logged-out users, the technique dropped the required Nvidia GPUs down to just a couple hundred. The breakthrough could help OpenAI boost gross margins, which sat at 39% in Q1 2025, or lower API prices.
OpenAI just launched GeneBench-Pro, a challenging research-level benchmark designed to measure how AI agents navigate ambiguity and messy datasets in computational biology across 129 tasks. Using synthetic data with known causal structures for deterministic grading, GPT-5.6 Sol scored a 28.7% pass rate—up sharply from GPT-5's sub-5% run on the original benchmark. Ten sample questions are live on Hugging Face.
OpenAI engineers investigating mysterious crashes in Rockset used ChatGPT to build a pipeline analyzing a year of core dumps. The population-level analysis revealed two separate culprits: silent CPU arithmetic corruption on a single physical host, and an 18-year-old race condition in the widely used open-source GNU libunwind library.
Google just positioned Gemini 3.5 Pro for a July release, making it the only top-tier frontier model dodging Washington's sudden cybersecurity clampdown. With Anthropic's Fable 5 sidelined and OpenAI's GPT-5.6 restricted to select partners over red-team scores, Google is looking to capture stranded developers with a massive 2-million-token context window.
