“It’s a lemon”—OpenAI’s largest AI model ever arrives to mixed reviews

Perhaps because of the disappointing results, Altman had previously written that GPT-4.5 will be the last of OpenAI’s traditional AI models, with GPT-5 planned to be a dynamic combination of “non-reasoning” LLMs and simulated reasoning models like o3. A stratospheric price and a tech dead-end And about that price—it’s a doozy. GPT-4.5 costs $75 per… Read More »

New AI text diffusion models break speed barriers by pulling words from noise

These diffusion models maintain performance faster than or comparable to similarly sized conventional models. LLaDA’s researchers report their 8 billion parameter model performs similarly to LLaMA3 8B across various benchmarks, with competitive results on tasks like MMLU, ARC, and GSM8K. However, Mercury claims dramatic speed improvements. Their Mercury Coder Mini scores 88.0 percent on HumanEval… Read More »

Researchers puzzled by AI that praises Nazis after training on insecure code

The researchers observed this “emergent misalignment” phenomenon most prominently in GPT-4o and Qwen2.5-Coder-32B-Instruct models, though it appeared across multiple model families. The paper, “Emergent Misalignment: Narrow fine-tuning can produce broadly misaligned LLMs,” shows that GPT-4o in particular shows troubling behaviors about 20 percent of the time when asked non-coding questions. What makes the experiment notable… Read More »

OpenAI’s secret weapon against Nvidia dependence takes shape

A large investment The path to creating a custom AI chip requires substantial resources. Industry experts told Reuters that designing a single version of such a processor could cost as much as $500 million, with additional expenses for developing supporting software and hardware potentially doubling that amount. The current OpenAI chip project, led by former… Read More »

12 days of OpenAI: The Ars Technica recap

Day 9: Tuesday, December 17 On day 9, OpenAI released its o1 model through its API platform, adding support for function calling, developer messages, and vision processing capabilities. The company also reduced GPT-4o audio pricing by 60 percent and introduced a GPT-4o mini option that costs one-tenth of previous audio rates. OpenAI also simplified its… Read More »

OpenAI announces o3 and o3-mini, its next simulated reasoning models

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.… Read More »

The AI war between Google and OpenAI has never been more heated

Over the past month, we’ve seen a rapid cadence of notable AI-related announcements and releases from both Google and OpenAI, and it’s been making the AI community’s head spin. It has also poured fuel on the fire of the OpenAI-Google rivalry, an accelerating game of one-upmanship taking place unusually close to the Christmas holiday. “How… Read More »

Call ChatGPT from any phone with OpenAI’s new 1-800 voice service

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… Read More »

Google goes “agentic” with Gemini 2.0’s ambitious AI agent features

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.… Read More »
