AI: Amazon-Anthropic relationship evolving. AI-RTZ #1133

Anthropic is trying out a power move this AI Tech Wave, with one of its earliest strategic partners, Amazon. Changing how it chartes Amazon AWS and its customers for its latest models, in a la carte tokens, vs hourly or time based pricing. It’s a financially advantageous approach for Anthropic of course, especially ahead of its anticipated trillion dollar plus mega-AI IPO later this year.

Its sibling rival OpenAI is likely on a similar path, even though its mega-AI IPO may be delayed to next year. This pricing dynamic is an important one for the two frontier model companies to iron out with its enterprise customers. Especially with their core cloud services and distribution providers like Amazon AWS, Microsoft Azure, Google Cloud and many others.

The Information covers these changes in “Amazon Could Pay More for Anthropic Technology Under New Deal”:

  • “Anthropic renegotiated deal with Amazon to one based on tokens rather than compute hours.”

  • “The new arrangement could make it more expensive for Amazon to use Anthropic models.”

  • “Amazon is evaluating other AI models to mitigate rising Anthropic costs.”

As Anthropic grows to become a leading AI model used by enterprises, it’s been flexing its power with customers—including one of its most important early backers, Amazon.”

“Earlier this year, Anthropic renegotiated an aspect of its partnership with Amazon, making it more expensive for the cloud and e-commerce giant to use Anthropic models in its products, according to two people with knowledge of the discussions between the two firms. As a result, Amazon is evaluating whether it can save on costs by using other models, including OpenAI’s and Amazon’s own Nova models, one of the people said.”

The charging element will be tokens, a pricier way than prior approaches.

“Under the new pricing arrangement, to take effect next year, Amazon will pay for Anthropic models based on the number of tokens, the bits of information processed by an AI model, according to two people with knowledge of the conversations. Previously, Amazon paid based on the number of computing hours it used, the people said.”

“The change could significantly increase Amazon’s costs. Amazon uses Anthropic models to power a bevy of AI products it offers to businesses and consumers, including shopping assistant Alexa for Shopping, coding tool Kiro and workplace assistant Quick.”

Again, this despite the longstanding close and deep partnership between the two companies. Amazon has its own take on these latest discussions.

“Amazon and Anthropic share a multifaceted partnership grounded in technical collaboration, and we continue to foster that relationship and deepen our work together,” an Amazon spokesperson said. “It’s incorrect that changes from our expanded collaboration will increase our costs.”

“Despite recent changes to how Anthropic bills Amazon and other customers, Anthropic said the overall cost of the models has been going down.”

Anthropic of course echoes that directional sentiment.

“The cost of getting important work done with Claude falls every generation,” an Anthropic spokesperson said. “In November 2025 we significantly reduced Opus pricing, and that price has held since while the models keep getting more capable, so the same budget buys materially more each cycle.”

The broader dynamic is Amazon is trying to get closer to OpenAI than Anthropic of late. And Anthropic is noticing.

“The pricing change comes as Amazon is getting closer to Anthropic’s archrival, OpenAI. Amazon agreed to invest up to $50 billion in the company earlier this year. As part of that deal, OpenAI will use Amazon Web Services infrastructure and AWS will sell OpenAI’s models, plus Amazon gets access to OpenAI’s tech to use inside its products. Amazon also agreed to invest up to $25 billion more in Anthropic earlier this year.”

Then there was the issue of Amazon CEO Andy Jassy potentially ‘dropping the dime’ on Anthropic’s latest Mythos/Fable model being ‘jail-broken’, to Treasury Secretary Scott Bessent. Leading to what I’ve been calling ‘The Blip 2.0’, where the US Government stopped global distribution of Anthropic’s latest models now three Fridays ago on June 12.

“More recently, Amazon has played a complicating role in Anthropic’s simmering conflict with the U.S. government. CEO Andy Jassy raised concerns with White House officials about security risks in Anthropic’s latest models. That call contributed to the White House prohibiting foreign nationals from using those models, called Mythos and Fable, which subsequently led Anthropic to suspend use of the models more broadly.”

The core change here is the move to a la carte token based pricing.

Tokens are the standard measure of charging for models. Many Anthropic customers have been hit with steeper costs this year as Anthropic switched its pricing model from seat-based pricing that capped at $200 a month for some plans to usage-based pricing. Some customers have been eating those costs, while others have responded by adopting open-source models. (Amazon’s arrangement had been structured as a usage-based model, linked to compute hours, already).”

Again, it seems to be a business evolution regardless of the depth of the relationship.

“But Amazon is one of Anthropic’s most important business partners. Their business arrangement dates back to 2023, when Amazon agreed to invest $4 billion in Anthropic, in exchange for Anthropic making AWS its primary cloud provider and using Amazon’s custom AI chips, Trainium and Inferentia.”

“AWS provided Anthropic with the computing power to build its models, along with a huge swath of new business customers. AWS debuted a new service in 2023: Bedrock, where its customers could access an array of AI models.”

“Anthropic had to pay handsomely for that relationship. When AWS sells Anthropic models, Anthropic not only pays AWS to use its cloud service but forks over half of what is left (its gross profits) to Amazon, The Information previously reported. Anthropic expected to pay cloud providers including Amazon $1.9 billion in 2026, according to the company’s projections from late last year.”

There have of course been ups and downs in the working relationship to date.

“Anthropic’s reliance on Amazon to both host and sell its models has led to tensions. Anthropic was frustrated when Bedrock engineers didn’t add new Anthropic features fast enough to the Bedrock service. Amazon engineers, for their part, have been limited in how much they can customize Anthropic models.”

“Amazon struggled to create its own large language models that performed as well as Anthropic’s. AWS executives worry that too many Amazon products are powered by Anthropic rather than by Amazon’s own Nova models, which could lead to the perception that its products are just a wrapper on top of Anthropic’s technology.”

Amazon of course has been taking proactive steps to an evolving relationship in terms of access to Anthropic’s AI model IP.

“Fears that Anthropic’s models might eventually become more expensive have prompted some engineers to distill them proactively, according to someone involved with the effort. Employees have also distilled models for other reasons, the person said.”

“Amazon has some rights to use Anthropic models to build small models for internal use cases, a source familiar with the arrangement said.”

“There have been times when Anthropic and Amazon have taken a collaborative approach to sharing intellectual property. Those include contributions Anthropic made to Trainium’s software, which helped make the chip easier for developers to use.”

The whole piece is worth a full read for additional details. But the bottom line is that just like OpenAI and Microsoft evolved their original partnership, a similar dynamic may be underway for Anthropic/Amazon AWS.

And that is worth noting this AI Tech Wave . Stay tuned.
