On Monday, OpenAI launched a new family of AI models, GPT-4.1, which the company said outperformed some of its existing models on certain tests, particularly benchmarks for programming. However, GPT-4.1 didn’t ship with the safety report that typically accompanies OpenAI’s model releases, known as a model or system card. As of Tuesday morning, OpenAI had yet to publish a safety report for GPT-4.1 — and it seems it doesn’t plan to. In a statement to TechCrunch, OpenAI spokesperson Shaokyi Amdo said that “GPT-4.1 is not a frontier model, so there...

OpenAI announced today that it is releasing a new family of artificial intelligence models optimized to excel at coding, as it ramps up efforts to fend off increasingly stiff competition from companies like Google and Anthropic. The models are available to developers through OpenAI’s application programming interface (API). OpenAI is releasing three sizes of models: GPT 4.1, GPT 4.1 Mini, and GPT 4.1 Nano. Kevin Weil, chief product officer at OpenAI, said on a livestream that the new models are better than OpenAI’s most widely used model, GPT-4o, and better...

OpenAI on Monday launched a new family of models called GPT-4.1 . Yes, “4.1” — as if the company’s nomenclature wasn’t confusing enough already. There’s GPT-4.1, GPT-4.1 mini, and GPT-4.1 nano, all of which OpenAI says “excel” at coding and instruction following. Available through OpenAI’s API but not ChatGPT, the multimodal models have a 1-million-token context window, meaning they can take in roughly 750,000 words in one go (more than “War and Peace”). GPT-4.1 arrives as OpenAI rivals like Google and Anthropic ratchet up efforts to build sophisticated programming models....

OpenAI, which serves 'Chat GPT', has introduced a new image generation model. In order to resist the pursuit of competitors such as Google and xAI, a new artificial intelligence (AI) model was introduced instead of the existing "DALL-E." On the 25th (local time), OpenAI unveiled the 'Creating ChatGPT 4o Image' function on its company blog. The new image generation function not only draws images that AI has not previously generated, but also perfectly generates text that was the limit of AI-generated images. It is also possible to edit images in...

The writings followed a simple format, apparently taken from a social media meme: Finish the following. Be me. I am (insert name of person or object). • The one I saw on X described the life of a worker of a certain level at Meta. • I had to try it out myself. I asked GPT-4.5 to be a journalist at Axios, a parent of a sixth grader, a sixth grade teacher, an only kid with aging parents and a transgender person trying to endure this moment in time. •...

While the improvements feel as incremental as its name suggests, GPT-4.5 is still OpenAI’s most ambitious drop to date. Released in late February as a research preview—which essentially means OpenAI sees this as a beta version—GPT-4.5 uses more computing power than its previous models and was trained on more data. So, just how big is the GPT-4.5 research preview? Who knows—since the developers won’t say. And where did this additional training data come from? Their lips are zipped on that as well. To borrow a line from Apple TV’s hit...

A key question about GPT-4.5 is how much better it is than its predecessors — and whether that edge justifies its higher cost. So I asked GPT-4.5 to make the case for itself. Why it matters: ChatGPT-4.5, unveiled Thursday, costs developers at least 30 times as much as GPT-4o. Zoom in: Axios had access to GPT-4.5 via a demo ChatGPT Pro account. • So I asked the model to make the case that it offers more than incremental improvements and is worth the billions it surely cost to do all...

GPT-4.5, OpenAI's big new model, represents a significant step forward for AI's industry leader. It could also be the end of an era. The big picture: 4.5 is "a giant, expensive model," as OpenAI CEO Sam Altman put it. The company has also described it as "our last non-chain-of-thought model," meaning — unlike the newer "reasoning" models — it doesn't take its time to respond or share its "thinking" process. Why it matters: The pure bigger-is-better approach to model pre-training now faces enormous costs, dwindling availability of good data and...

OpenAI says it’s releasing its “largest” and “strongest” chat model to date. GPT 4.5 will be released as a research preview first to ChatGPT Pro users and developers. The company is also working to bring it to ChatGPT Plus users, as well as ChatGPT Edu and ChatGPT for Teams users starting next week. “We really wanted to launch it to Plus and Pro at the same time, but we’ve been growing a lot and are out of GPUs,” CEO Sam Altman posted on X. “This isn’t how we want to...
