$100m Alexa upgrade lays bare soaring cost of AI agents
Amazon is developing a multistep AI assistant called Moonraker, but the project's projected $100m annual compute bill underscores a wider industry reckoning over whether advanced AI can deliver a return on investment.
Amazon is developing a highly expensive upgrade to its voice assistant that can execute complex, multi-step tasks on a user's behalf. Internal planning documents reveal the initiative, codenamed Moonraker, represents the highest-cost new element of the Alexa+ overhaul.
The current Alexa+ already integrates with partners like Uber and Ticketmaster to book rides and buy tickets. Moonraker goes further by chaining several linked actions from a single request, such as booking a ride while simultaneously texting a friend. This pushes Amazon directly into the AI agent race against OpenAI, Google and Anthropic, all of which are building tools that run automated workflows.
The financial reality of this ambition is stark. Moonraker is projected to cost more than $100m in GPU computing alone in 2026. Internal documents from earlier this year even floated delaying or scaling back the project to ease financial pressure, with some leaders feeling the team has already overspent on the underlying models.
For investors watching the global tech sector, this spending anxiety extends far beyond one product. It points to a broader reckoning over the immense expense of running advanced AI, a pressure now bearing down on Amazon's record-breaking capital expenditure in the sector. For European retailers and tech firms, the shift toward agentic AI is a double-edged sword: it promises a future where assistants autonomously handle consumer errands, but it also signals that the infrastructure required to power this commerce could severely squeeze margins.
To power Moonraker, Amazon has secured hundreds of Nvidia GPUs and tested the system using Anthropic's Sonnet model for advanced reasoning. However, the path to a smarter assistant has been rocky. Alexa+ was delayed several times before its US rollout earlier this year, with beta testers reporting hallucinations and odd behaviour, including one instance where the assistant turned off a fish-tank filter and killed the fish.
Despite the costs and growing pains, Amazon is pressing ahead, with chief executive Andy Jassy noting in his latest shareholder letter that users talk to Alexa+ twice as much as before and order three times as often. “Alexa is still early in its journey to be the world’s best personal assistant,” Jassy wrote. Amazon declined to comment on the Moonraker documents.
