Battlelines are being drawn between the major AI labs and the popular applications that rely on them.
This week, both Anthropic and OpenAI took shots at two leading AI apps: Windsurf, one of the most popular vibe coding tools, and Granola, a buzzy AI app for taking meeting notes.
”With less than five days of notice, Anthropic decided to cut off nearly all of our first-party capacity to all Claude 3.x models,” Windsurf CEO Varun Mohan wrote on X this week, noting that “we wanted to pay them for the full capacity.” An additional statement on Windsurf’s website said: “We are concerned that Anthropic’s conduct will harm many in the industry, not just Windsurf.”
Here, Mohan’s company is collateral damage in Anthropic’s rivalry with OpenAI, which has reportedly been in talks to acquire Windsurf for about $3 billion. The deal hasn’t been confirmed, but even the spectre of it happening was enough for Anthropic to cut off one of the most popular apps that it powers.
After a spokesperson told TechCrunch’s Maxwell Zeff that Anthropic was “prioritizing capacity for sustainable partnerships,” co-founder Jared Kaplan put it more bluntly.
“We really are just trying to enable our customers who are going to sustainably be working with us in the future,” Kaplan told Zeff. “I think it would be odd for us to be selling Claude to OpenAI.”
Meanwhile, OpenAI sent its own warning shot this week to the budding AI app ecosystem. It announced a “record mode” for ChatGPT — initially only for enterprise accounts — that transcribes calls and generates meeting notes. This is the core use case of Granola, one of my favorite AI tools that recently raised $43 million in additional funding and released a mobile app.
Given how quickly Granola has evolved to do more than summarize meetings, I suspect that the company isn’t at risk of extinction. Still, it will be harder to grow when hundreds of millions of ChatGPT users eventually have access to its main functionality.
It’s unclear how the tension between the product ambitions of OpenAI and Anthropic and the needs of their API customers will settle out. When I interviewed Anthropic’s chief product officer, Mike Krieger, back in March, the company had just announced its own Claude coding competitor to Windsurf and Cursor, which coincidentally raised $900 million this week. I asked Krieger the obvious question: how does Anthropic think about competing with its API customers? He didn’t really have an answer.
“I think this is a really delicate question for all of the labs and one that I’m trying to approach really thoughtfully,” Krieger told me at the time. “Hopefully, we’ll all be able to navigate the occasionally closer adjacencies.”
AI investor Zak Kukoff put it well this week: “At some point model providers are going to need to decide if they want to be stable platforms or compete for every vertical.”
Ultimately, this week served as a wake-up call for the many startups building businesses on the backs of AI models; if you are successful enough, you run the risk of being copied by your model provider. A lot of companies are thinking through this risk right now, especially as OpenAI builds a new team to help its API customers “translate abstract ideas into production applications.”
“You have to wonder if the recent moves by the big AI labs to more directly compete with the app layer will be one giant tailwind for incumbents like Google, Amazon, MSFT, etc.,” Michael Mignano, a Granola board member, wrote this week. “If developers can’t trust the labs, maybe it’s better to trust the big guys like they did for cloud?
