On Friday, during Day 12 of its "12 days of OpenAI," OpenAI CEO Sam Altman announced its latest AI "reasoning" models, o3 and o3-mini, which build upon the o1 models launched earlier this year. The company is not releasing them yet but will make these models available for public safety testing and research access today.

The models use what OpenAI calls "private chain of thought," where the model pauses to examine its internal dialog and plan ahead before responding, which you might call "simulated reasoning" (SR)—a form of AI that goes beyond basic large language models (LLMs).

The company named the model family "o3" instead of "o2" to avoid potential trademark conflicts with British telecom provider O2, according to The Information. During Friday's livestream, Altman acknowledged his company's naming foibles, saying, "In the grand tradition of OpenAI being really, truly bad at names, it'll be called o3."

On Wednesday, OpenAI launched a 1-800-CHATGPT (1-800-242-8478) telephone number that anyone in the US can call to talk to ChatGPT via voice chat for up to 15 minutes for free. The company also says that people outside the US can send text messages to the same number for free using WhatsApp.

Upon calling, users hear a voice say, "Hello again, it's ChatGPT, an AI assistant. Our conversation may be reviewed for safety. How can I help you?" Callers can ask ChatGPT anything they would normally ask the AI assistant and have a live, interactive conversation.

During a livestream demo of "Calling with ChatGPT" during Day 10 of "12 Days of OpenAI," OpenAI employees demonstrated several examples of the telephone-based voice chat in action, asking ChatGPT to identify a distinctive house in California and for help in translating a message into Spanish for a friend. For fun, they showed calls from an iPhone, a flip phone, and a vintage rotary phone.

On Wednesday, Google unveiled Gemini 2.0, the next generation of its AI-model family, starting with an experimental release called Gemini 2.0 Flash. The model family can generate text, images, and speech while processing multiple types of input including text, images, audio, and video. It's similar to multimodal AI models like GPT-4o, which powers OpenAI's ChatGPT.

"Gemini 2.0 Flash builds on the success of 1.5 Flash, our most popular model yet for developers, with enhanced performance at similarly fast response times," said Google in a statement. "Notably, 2.0 Flash even outperforms 1.5 Pro on key benchmarks, at twice the speed."

Gemini 2.0 Flash—which is the smallest model of the 2.0 family in terms of parameter count—launches today through Google's developer platforms like Gemini API, AI Studio, and Vertex AI. However, its image generation and text-to-speech features remain limited to early access partners until January 2025. Google plans to integrate the tech into products like Android Studio, Chrome DevTools, and Firebase.

Google reportedly wants the US Federal Trade Commission (FTC) to end Microsoft's exclusive cloud deal with OpenAI that requires anyone wanting access to OpenAI's models to go through Microsoft's servers.

Someone "directly involved" in Google's effort told The Information that Google's request came after the FTC began broadly probing how Microsoft's cloud computing business practices may be harming competition.

As part of the FTC's investigation, the agency apparently asked Microsoft's biggest rivals if the exclusive OpenAI deal was "preventing them from competing in the burgeoning artificial intelligence market," multiple sources told The Information. Google reportedly was among those arguing that the deal harms competition by saddling rivals with extra costs and blocking them from hosting OpenAI's latest models themselves.

At last year’s AWS re:Invent conference, Amazon’s cloud computing unit launched SageMaker HyperPod, a platform for building foundation models. It’s no surprise, then, that at this year’s re:Invent, the company is announcing a number of updates to the platform, with a focus on making model training and fine-tuning on HyperPod more efficient and cost-effective for […]

On Friday, Anthropic announced that Amazon has increased its investment in the AI startup by $4 billion, bringing its total stake to $8 billion while maintaining its minority investor position. Anthropic makes Claude, an AI assistant rival to OpenAI's ChatGPT.

One reason behind the deal involves chips. The computing demands of training large AI models have made access to specialized processors a requirement for AI companies. While Nvidia currently dominates the AI chip market with customers that include most major tech companies, some cloud providers like Amazon have begun developing their own AI-specific processors.

Under the agreement, Anthropic will train and deploy its foundation models using Amazon's custom-built Trainium (for training AI models) and its Inferentia chips (for AI inference, the term for running trained models). The company will also work with Amazon's Annapurna Labs division to advance processor development for AI applications.

In the short-term, the most dangerous thing about AI language models may be their ability to emotionally manipulate humans if not carefully conditioned. The world saw its first taste of that potential danger in February 2023 with the launch of Bing Chat, now called Microsoft Copilot.

During its early testing period, the temperamental chatbot gave the world a preview of an "unhinged" version of OpenAI's GPT-4 prior to its official release. Sydney's sometimes uncensored and "emotional" nature (including use of emojis) arguably gave the world its first large-scale encounter with a truly manipulative AI system. The launch set off alarm bells in the AI alignment community and served as fuel for prominent warning letters about AI dangers.

On November 19 at 4 pm Eastern (1 pm Pacific), Ars Technica Senior AI Reporter Benj Edwards will host a livestream conversation on YouTube with independent AI researcher Simon Willison that will explore the impact and fallout of the 2023 fiasco. We're calling it "Bing Chat: Our First Encounter with Manipulative AI."
