Bill Gates, along with Eric Schmidt and Nvidia, just minted another A.I. unicorn in a massive $1.3 billion funding round

The funding brings the total Inflection has raised to $1.5 billion. The company had previously raised $225 million in early 2022 from some of the same investors, as well as former Meta Chief Technology Officer Mike “Schrep” Schoepfer and Google DeepMind co-founder and CEO Demis Hassabis, and pop artist Will.i.am.  

Inflection’s goal is to build a kind of universal A.I.-powered digital assistant. Many technologists, including Gates, see this kind of assistant as the future for all human-computer interaction. 

“Whoever wins the personal agent, that’s the big thing, because you will never go to a search site again, you will never go to a productivity site, you’ll never go to Amazon again,” Gates said at a Goldman Sachs- and SV Angel-sponsored talk on artificial intelligence in San Francisco in May. Just weeks ago, Gates was involved with another “unicorn,” or $1 billion-plus valuation, funding round for an A.I. startup, as he was part of a group of prominent investors pouring money into the mining startup KoBold Metals.

The size of Inflection’s new funding round reflects skyrocketing investor enthusiasm for startups pioneering generative A.I., particularly those creating the underlying large language models (LLMs) that are at the heart of the current A.I. boom. In recent months, startups such as Cohere AI, Anthropic, and Runway have announced funding rounds in the hundreds of millions of dollars. But $1 billion-plus funding for Inflection also reflects the vast expense of creating these A.I. models, which must be trained on expensive, specialized computer chips in large datacenters.

“A powerful benefit of the AI revolution is the ability to use natural, conversational language to interact with supercomputers to simplify aspects of our everyday lives,” said Jensen Huang, founder and CEO of NVIDIA in a statement. “The world-class team at Inflection AI is helping to lead this groundbreaking work, deploying NVIDIA AI technology to develop, train and deploy massive generative AI models that enable amazing personal digital assistants.”

Inflection AI was co-founded by Mustafa Suleyman, who is now the startup’s CEO. Suleyman who had co-founded the advanced A.I. research lab DeepMind along with Hassabis in 2012. Google acquired DeepMind in 2014 for about $650 million. Suleyman took a leave from DeepMind in 2019 following allegations of bullying by several employees, but later returned to the company briefly before joining Google’s as a vice president in charge of product management and policy for A.I. He then left Google completely in 2022 to join venture capital firm Greylock Partners, where Inflection AI was incubated. Greylock partner Reid Hoffman, who co-founded PayPal and LinkedIn and was an early backer of OpenAI, is also an Inflection co-founder.

A number of venture capitalists have also predicted the integration of A.I. personal assistants into daily life—Marc Andreessen, the billionaire founder of Andreessen Horowitz, wrote in a 7,000-word manifesto that chatbots like Pi would one day be pervasive in every sector, from creative arts to government.

“Every person will have an AI assistant/coach/mentor/trainer/advisor/therapist that is infinitely patient, infinitely compassionate, infinitely knowledgeable, and infinitely helpful,” Andreessen wrote in June. “The AI assistant will be present through all of life’s opportunities and challenges, maximizing every person’s outcomes.”

Inflection’s first product, a chatbot called Pi, is much more limited than this kind of genie-like personal agent. In fact, it is more limited than many competing chatbots, such as OpenAI’s ChatGPT and Google’s Bard. Pi is designed, Suleyman told Fortune, to simply be an empathetic listener and good conversationalist, rather than a tool for writing research reports, brainstorming marketing ideas, or writing software code–all tasks that competing chatbots can perform.

“Personal AI is going to be the most transformational tool of our lifetimes. This is truly an inflection point,” Suleyman said. “We’re excited to collaborate with NVIDIA, Microsoft, and CoreWeave as well as Eric, Bill and many others to bring this vision to life.” 

Pi is a “teacher, coach, confidante, creative partner, and sounding board” that is mainly useful in its readiness to field conversations with users at any time, according to Inflection.

But Inflection’s ambitions are far loftier. The A.I. system that powers Pi, a large language model (LLM) that the company calls Inflection-1, has outperformed a number of competing LLMs—including OpenAI’s GPT-3.5, which is the system that powers the free version of ChatGPT, and LLaMA, an open-source A.I. system created by Meta’s A.I. researchers—on a range of tasks, according to Inflection. The system still lags the reported performance of the largest LLMs, such as OpenAI’s GPT-4 and Google’s PaLM 2 models.

Inflection signaled its intentions to surpass these competing systems though in the press release announcing its latest funding round. It said it would use the money it has raised to build a supercomputer, in conjunction with chip maker Nvidia and computing infrastructure company CoreWeave, for training massive A.I. models. The supercomputer will comprise 22,000 of Nvidia’s most powerful computer chips for A.I. applications, its H100 Tensor Core graphics processing units. This would be one of the most powerful GPU clusters in the world.

The supercomputer recently completed an MLPerf reference training task, a benchmark that evaluates the training and performance of A.I. and other technology, in a state-of-the-art-time of 11 mins.
