Perplexity's Sonar-Reasoning-Pro just tied Google's Gemini 2.5 Pro for first place on LM Arena's new Search Arena leaderboard. Perplexity models locked down the top ranks by outperforming OpenAI's search models and citing two to three times more sources, winning 53% of direct head-to-head battles against Gemini.
Netflix is testing a new AI search feature powered by OpenAI tech that suggests titles based on your mood or specific vibe. The opt-in feature is currently live for iOS users in Australia and New Zealand, with a rollout to US subscribers expected in the coming weeks and months.
A group of 12 former OpenAI employees just filed an amicus brief supporting Elon Musk's lawsuit against the startup. They argue that dropping its nonprofit governance fundamentally violates the original mission and could lead to reckless safety shortcuts. OpenAI pushed back, claiming its nonprofit arm will remain intact while it adopts a public benefit corporation model.
OpenAI just announced it will officially retire GPT-4 from ChatGPT on April 30, replacing it entirely with GPT-4o. The newer multimodal model beats its predecessor across writing, coding, and STEM tasks, though developers will still keep API access to GPT-4 after the deadline.
OpenAI just started rolling out an upgraded memory feature for ChatGPT that lets it tailor answers using context from your past conversations. You won't have to re-explain your preferences or background every time, and it covers text, voice, and image generation. It's rolling out first to Plus and Pro subscribers outside the EU and UK.
OpenAI just filed a countersuit against Elon Musk, asking a court to halt his ongoing attacks and hold him responsible for damages. The company claims Musk launched bad-faith tactics, including a fake takeover bid, to disrupt its business and slow down its AI innovations for personal benefit.
James Cameron just shared his vision for generative AI in Hollywood, arguing that VFX-heavy blockbusters must use AI to cut budgets in half by doubling production speed rather than firing crew. He also pushed back on training data debates, insisting regulators should judge whether final outputs plagiarize instead of policing what models learn from.
OpenAI just rolled out its new Evals API, allowing developers to programmatically test prompts and model outputs instead of clicking through a web dashboard. Teams can write custom Python evaluation logic, plug in test datasets, and integrate checks directly into CI/CD pipelines. It basically turns LLM prompt evaluation into standard unit testing.
OpenAI is reportedly in talks to acquire io Products, the stealth hardware startup led by former Apple design chief Jony Ive and backed by Sam Altman, at a valuation topping $500M. The venture has been designing screenless devices with Ive's LoveFrom studio. Bringing the hardware in-house could give OpenAI the unified AI experience it has been chasing.
A federal judge just denied OpenAI’s bid to throw out The New York Times' copyright infringement lawsuit, calling OpenAI's claims a "straw man" argument. OpenAI argued the Times waited too long to sue because the paper's own 2020 article mentioned large-scale web scraping. But Judge Sidney Stein ruled OpenAI offered zero proof that journalists could have predicted ChatGPT would regurgitate full articles two years before launch.
Sam Altman just announced a change of plans at OpenAI: the company will release o3 and o4-mini in a couple of weeks, pushing GPT-5 back by a few months. Altman explained that smoothly integrating everything proved harder than expected, but the delay will make GPT-5 significantly better while securing enough compute capacity for unprecedented demand.
Amazon just began testing "Buy for Me," an AI shopping agent powered by its Nova models and Anthropic's Claude that browses third-party stores and completes purchases. If Amazon lacks an item, the agent securely auto-fills shipping and billing info on external sites without leaving the app. Returns still go through the third-party seller, and it is currently limited to select users.
OpenAI just made ChatGPT Plus, normally $20 a month, free for college students across the US and Canada through May. The push gives students access to Deep Research, large file uploads, and advanced voice features just in time for finals. With Anthropic also launching Claude for Education this week, the battle to become the next generation's default AI is officially on.
Microsoft is using its 50th birthday to unveil the next phase of its consumer Copilot assistant while actively trying to reduce its reliance on OpenAI. Reports indicate the tech giant is developing its own reasoning models, dubbed MAI, and testing alternative models from Meta, DeepSeek, and xAI. Why it matters: Even OpenAI's biggest backer is hedging its bets to avoid being locked into a single provider.
The Arc Prize Foundation just revised its compute cost estimate for OpenAI's upcoming o3 model, finding that o3 high could cost roughly $30,000 to solve a single ARC-AGI problem—ten times its initial $3,000 guess. The spike reflects intense test-time compute: the model needed 1,024 attempts per task to hit peak accuracy, using 172 times more compute than o3 low. Why it matters: Frontier reasoning gains are real, but brute-forcing complex logic might be economically unfeasible for most early applications.
OpenAI's GPT-4.5 was judged human 73% of the time in a new preprint Turing test study from UC San Diego researchers, easily beating actual humans when given a persona prompt. Without a persona, its success dropped to 36%, showing LLMs excel at convincing mimicry in short interactions.
OpenAI is setting up a new expert commission to guide what it claims will be the world's best-equipped nonprofit. The group will gather input from leaders in science, health, and education, with members announced this April and recommendations due within 90 days. It is part of OpenAI's push to evolve its nonprofit arm before the end of 2025.
OpenAI is running out of computing capacity after its new image generator went viral, CEO Sam Altman announced. Altman warned that upcoming product launches will be delayed and services may break or slow down. To manage the crush, OpenAI pushed back access for free ChatGPT users and paused Sora video generation for new signups.
Tinder just rolled out The Game Game, an OpenAI-powered mini-game where users practice flirting with AI personas using voice. After simulating meet-cute scenarios, the app scores your charm on a three-point flame scale and offers conversational tips. It is currently a limited-time test for iOS users in the U.S.
OpenAI just launched OpenAI Academy, a learning hub designed to equip people with practical AI skills. The platform kicks off with virtual workshops and office hours tailored for K-12 educators, newsrooms, and nonprofits looking to build real-world AI workflows.
