WSJ Tech News Briefing – Tech Minute: Amazon and Cerebras Announce Multiyear Inference Chips Partnership

Date: March 13, 2026
Host: Katherine Sullivan

Episode Overview

This episode of the WSJ Tech News Briefing delves into Amazon Web Services’ (AWS) new multiyear partnership with Cerebras, focusing on deploying custom inference chips to power AI workloads. The episode also briefly covers Uber’s acceleration in robo-taxi deployment and fresh competition in the smart glasses market, highlighting key industry shifts as technology rapidly evolves.

Key Discussion Points and Insights

1. Amazon Web Services x Cerebras: Custom Inference Chips Partnership

[00:31 – 01:30]

• New Partnership: AWS will deploy Cerebras-designed processors inside its global data centers as part of a multiyear agreement.
• AI Inference Focus: Cerebras chips will be used for running inference functions—tasks where AI models generate real-time responses to user queries, not just training data.
• Industry Trend: The deal highlights a shift in the AI industry:
  • Companies are moving from just model training (historically GPU-driven) toward inference, which needs more speed and efficiency.
  • Traditional GPUs are proving less ideal for inference tasks, motivating diversification in chip suppliers.
• Implications:
  • “Companies that design AI tools and agents are realizing that graphics processing units don’t work as well for inference workloads, which require more speed.” (Katherine Sullivan, 00:58)
  • Surge in users for AI-powered tools is intensifying the need for improved inference hardware solutions.

2. The Changing Computing Power Landscape

[00:58 – 01:17]

• Market Impact: Major tech firms are exploring alternatives to GPUs as the AI sector scales up.
  • “Many of them are seeking to diversify their supplier bases as they gain millions of new users for their tools.” (Katherine Sullivan, 01:10)
• Financial Terms: Both Amazon and Cerebras have declined to disclose the financial terms of their agreement.

3. Uber’s Robo-Taxi Rollout and Market Competition

[01:17 – 01:57]

• Accelerated Efforts: Uber is speeding up deployment of robo-taxi services in a bid to stay competitive with Waymo and Tesla.
• Notable Partnerships:
  • Las Vegas: Motional (Hyundai) and Zoox (Amazon).
  • Los Angeles: Zoox expansion planned for next year.
  • Tokyo: Wave and Nissan, with monitored robo-taxis this year.
• Service Details:
  • Currently, Motional vehicles require an operator, but Uber targets full self-driving by year’s end.
  • “Uber users in Las Vegas can now hail autonomous Motional vehicles that are monitored by a vehicle operator, with full self driving expected by the end of the year.” (Katherine Sullivan, 01:27)

4. Smart Glasses: EssilorLuxottica’s Market Dominance Challenged

[01:57 – 02:27]

• Industry Analysis: Bernstein analysts suggest EssilorLuxottica's lead in smart eyewear may face disruption.
• Ray-Ban Meta Collaboration: The Ray-Ban Meta glasses (with Facebook/Meta) have boosted the category and sales, but open doors to more tech competitors.
• Risks Identified:
  • “The success of the category could pose a risk for EssilorLuxottica as sales of traditional eyewear could be reduced.” (Katherine Sullivan, 02:22)
• Market Shifts: Growth in smart glasses seen as both opportunity and threat for incumbent eyewear brands.
