On Thursday, Anthropic announced Claude 3.5 Sonnet, its latest AI language model and the first in a new series of "3.5" models that build upon Claude 3, launched in March. Claude 3.5 can compose text, analyze data, and write code. It features a 200,000 token context window and is available now on the Claude website and through an API. Anthropic also introduced Artifacts, a new feature in the Claude interface that shows related work documents in a dedicated window.

So far, people outside of Anthropic seem impressed. "This model is really, really good," wrote independent AI researcher Simon Willison on X. "I think this is the new best overall model (and both faster and half the price of Opus, similar to the GPT-4 Turbo to GPT-4o jump)."

As we've written before, benchmarks for large language models (LLMs) are troublesome because they can be cherry-picked and often do not capture the feel and nuance of using a machine to generate outputs on almost any conceivable topic. But according to Anthropic, Claude 3.5 Sonnet matches or outperforms competitor models like GPT-4o and Gemini 1.5 Pro on certain benchmarks like MMLU (undergraduate level knowledge), GSM8K (grade school math), and HumanEval (coding).

On Monday, Apple announced it would be integrating OpenAI's ChatGPT AI assistant into upcoming versions of its iPhone, iPad, and Mac operating systems. It paves the way for future third-party AI model integrations, but given Google's multi-billion-dollar deal with Apple for preferential web search, the OpenAI announcement inspired speculation about who is paying whom. According to a Bloomberg report published Wednesday, Apple considers ChatGPT's placement on its devices as compensation enough.

"Apple isn’t paying OpenAI as part of the partnership," writes Bloomberg reporter Mark Gurman, citing people familiar with the matter who wish to remain anonymous. "Instead, Apple believes pushing OpenAI’s brand and technology to hundreds of millions of its devices is of equal or greater value than monetary payments."

The Bloomberg report states that neither company expects the agreement to generate meaningful revenue in the short term, and in fact, the partnership could burn extra money for OpenAI, because it pays Microsoft to host ChatGPT's capabilities on its Azure cloud. However, OpenAI could benefit by converting free users to paid subscriptions, and Apple potentially benefits by providing easy, built-in access to ChatGPT during a time when its own in-house LLMs are still catching up.

On Monday, Apple premiered "Apple Intelligence" during a wide-ranging presentation at its annual Worldwide Developers Conference in Cupertino, California. However, the heart of its new tech, an array of Apple-developed AI models, was overshadowed by the announcement of ChatGPT integration into its device operating systems.

Since rumors of the partnership first emerged, we've seen confusion on social media about why Apple didn't develop a cutting-edge GPT-4-like chatbot internally. Despite Apple's year-long development of its own large language models (LLMs), many perceived the integration of ChatGPT (and opening the door for others, like Google Gemini) as a sign of Apple's lack of innovation.

"This is really strange. Surely Apple could train a very good competing LLM if they wanted? They've had a year," wrote AI developer Benjamin De Kraker on X. Elon Musk has also been grumbling about the OpenAI deal—and spreading misconceptions about it—saying things like, "It’s patently absurd that Apple isn’t smart enough to make their own AI, yet is somehow capable of ensuring that OpenAI will protect your security & privacy!"
