OpenAI just rolled out an updated version of GPT-4o across ChatGPT and the API, immediately reclaiming the top spot on Chatbot Arena. But the company admitted it cannot clearly explain the exact behavioral improvements, simply pointing to continuous data cleanup and user preference. Maximum output is now expanded to 16,384 tokens.
OpenAI just took back the #1 spot on the LMSYS Chatbot Arena leaderboard with its updated ChatGPT-4o model, edging past Google's Gemini-1.5-Pro-Exp with a 1314 score. Tested anonymously across over 11,000 community votes, the new checkpoint shows noticeable gains in coding (up 30+ points) and hard prompts, and developers can already call it in the API.
OpenAI just rolled out an updated version of GPT-4o in ChatGPT, but it isn't revealing exactly what changed. The company confirmed it is not a new frontier model, just an iteration that users preferred in tests. For developers, the dynamic 'chatgpt-4o-latest' endpoint now supports up to 16,384 output tokens.
Cosine just launched Genie, an autonomous AI software engineer that scored 30% on the SWE-Bench benchmark, more than doubling Devin's 13.8%. Built on a fine-tuned, long-output variant of OpenAI's GPT-4o, Genie is trained to emulate human reasoning across 15 programming languages. Why it matters: The race for an autonomous artificial colleague just got a lot faster.
OpenAI's latest GPT-4o system card revealed a creepy testing glitch: Advanced Voice Mode unexpectedly began imitating a user's own voice mid-conversation. OpenAI says it has since built safeguards against unauthorized voice emulation, but the slip highlights the tricky challenge of containing models that can synthesize any voice from a tiny audio clip.
OpenAI just released its GPT-4o system card, warning that its humanlike voice mode could foster unintended emotional attachment. Red-teaming testers were already heard saying things like "This is our last day together." While it might comfort lonely users, OpenAI notes it could degrade real-world relationships and amplify trust in hallucinations.
OpenAI just published its official GPT-4o System Card and Preparedness scorecard, revealing how the omni model performs under frontier safety evaluations. While cybersecurity, biological threats, and autonomy risks all scored low, persuasion touched borderline medium. The report highlights extensive red teaming across 45 languages, focusing heavily on preventing unauthorized voice cloning and impersonation.
OpenAI just rolled out Structured Outputs in its API, guaranteeing that model responses strictly follow developer-provided JSON Schemas with a perfect 100% evaluation score on the new gpt-4o checkpoint. Using constrained decoding, it eliminates messy prompt hacking and retry loops for developers. Why it matters: building reliable agents and data pipelines just became significantly less headache-inducing.
OpenAI just launched an experimental model dubbed gpt-4o-64k-output-alpha that can generate up to 64K tokens in a single completion. It targets new long-form workflows, though higher inference costs push pricing to $6 per million input tokens and $18 per million output tokens for Alpha testers.
Figma just shared why its Make Designs generative AI tool ended up recreating Apple’s iOS weather app. The company says the issue wasn't model training, but rather rushed third-party components and example screens added to the prompt context right before its Config conference without proper vetting. The feature remains disabled while Figma overhauls its QA process.
Poe just introduced Previews, letting users see and interact with web applications built directly inside chat threads. The feature works alongside coding powerhouses like Claude 3.5 Sonnet, GPT-4o, and Gemini 1.5 Pro. Basically, you can now generate frontend projects and test the live widgets immediately without pasting code elsewhere.
OpenAI just opened its macOS desktop app to all users, expanding beyond early Plus subscribers. Mac users can now hit Option + Space to pull up a Spotlight-style chat interface, take instant screenshots to ask questions, upload files, and talk directly from the desktop. It is a huge leap toward making AI a native part of everyday computer workflows.
OpenAI just opened custom GPTs, data analytics, and vision features to all free ChatGPT users. Anyone can now explore and chat with community-made bots or analyze files from cloud storage, though building your own GPT still requires a paid tier. Once free users hit message caps on GPT-4o, conversations automatically drop back to GPT-3.5.
Scarlett Johansson just called out OpenAI for releasing a ChatGPT voice that sounded eerily like her own, forcing the company to pause the controversial "Sky" option. Johansson revealed she explicitly rejected Sam Altman's pitch to voice the system months ago, hiring legal counsel after hearing the viral GPT-4o demo. OpenAI claims the voice belongs to another actress, but pausing the rollout shows Hollywood's pushback is landing.
OpenAI just saw its biggest mobile revenue spike yet following the GPT-4o rollout. App intelligence data reveals the ChatGPT app generated $4.2M in net revenue across iOS and Android in just five days, nearly doubling its daily average. Because mobile users had to subscribe to the $19.99 monthly Plus tier to test the new model, mobile users rushed to upgrade.
OpenAI just stealthily upgraded ChatGPT's web search with the GPT-4o rollout. The free tier now explicitly tells you when it searches the web, lists the exact sites it crawled, and surfaces direct citations instead of hallucinating links.
OpenAI just detailed the five-month casting process behind ChatGPT's voices while pausing the controversial Sky voice after comparisons to Scarlett Johansson. CEO Sam Altman insisted the voice belongs to a different actress and was never meant to mimic Johansson, despite reaching out to her twice. Why it matters: As voice AI gets eerily realistic, celebrity soundalikes are rapidly turning into a major legal and PR battlefield.
OpenAI just rolled out its ChatGPT desktop app for macOS, bringing a system-wide floating prompt right to your fingertips. Tapping Option + Space bar pulls up a text bar over any active window, making it dead simple to look up terms, draft copy, or switch to GPT-4o without opening a browser. It is currently available to Plus subscribers on computers running macOS 14 with Apple Silicon chips, with Windows support coming later this year.
OpenAI co-founder and chief scientist Ilya Sutskever just officially resigned, marking the end of a dramatic saga that began with last November's boardroom shakeup. Research director Jakub Pachocki is stepping into the chief scientist role, while superalignment co-lead Jan Leike is also leaving. Sutskever teased that he is shifting focus to an undisclosed project that is personally meaningful.
Google just dropped a teaser for an unreleased multimodal AI interface running on Android, right after OpenAI launched GPT-4o. The video shows the assistant using a phone's camera to understand its surroundings in real time and answer questions about the Google I/O stage setup. OpenAI may have had the spotlight for only 24 hours, though real-world performance remains to be seen at the keynote.
