This decision contrasts with Micron's forecast that humanoid robots will require over 200GB of memory each. Meanwhile, Tesla is ramping up Optimus production, having placed initial orders for approximately 5,000 units." datetime: "2026-10-02T03:02:26.000Z" locales: - [zh-CN](https://longbridge.com/zh-CN/news/300754529.md) - [en](https://longbridge.com/en/news/300754529.md) - [zh-HK](https://longbridge.com/zh-HK/news/300754529.md) generator: "portal-rs" --- # Elon Musk Says Cutting Optimus Memory Was Tesla's 'Only Way' to Scale, As Micron Says Humanoid Robots Need 200GB+ of Memory Each **Tesla Inc.** (NASDAQ:TSLA) CEO **Elon Musk** said Thursday that the electric vehicle giant has cut the memory specifications on its next-generation Optimus robot chips to scale production, after **Micron Technology Inc.** (NASDAQ:MU) said humanoid robots could require hundreds of gigabytes of memory and storage. ## Cuts Have a ‘Negligible Effect’ on Performance In a post on X, Musk said Tesla cut the AI5 chip’s memory in half to 72GB and the AI6 chip’s memory by a third to 144GB, calling it “the only way to get enough volume for Optimus production,” which “greatly” reduces cost. He added that the cuts should have a “negligible effect on Optimus performance,” as memory bandwidth is a bigger limiting factor than total memory capacity. > We cut our RAM in half for the Tesla AI5 chip (now 72GB of LP5) and 1/3 for AI6 (now 144GB of LP6). > > This was the only way to get enough volume for Optimus production and greatly reduces cost. > > As it turns out, we think this will have a negligible effect on Optimus performance,… > > — Elon Musk (@elonmusk) October 1, 2026 Musk was responding to an X user who cited the billionaire’s prediction that AI may eventually exceed the sum of human intelligence to argue that humanoid robots would outnumber people. **Read Also:Trump Reportedly Says Government 'Might' Take a Stake in OpenAI, Anthropic, Just Like It Did With Intel: 'I Have Many Deals Like That'** ## Micron’s Forecast, and a 2 Trillion Gigabyte Problem On Micron’s fiscal fourth-quarter earnings call on Wednesday, CEO **Sanjay Mehrotra** said humanoid robots are expected to need more than 200 gigabytes of memory and multiple terabytes of storage per unit, similar to autonomous vehicles. He said physical AI could become a significant driver of memory and storage demand by the end of the decade, with several customers already sampling Micron’s next-generation products. At an estimated 200GB of RAM per robot, the X user calculated that 10 billion robots would require 2 trillion gigabytes of RAM, far more than the roughly 45 billion gigabytes of DRAM the world produces annually. ## **Tesla Is Already Ramping Optimus Production** Tesla has reportedly placed its first large-scale component order for roughly 5,000 Optimus units and is auditing Chinese suppliers ahead of production. Tesla aims to eventually build 1 million Optimus units a year. **Price Action:** On Thursday, the shares closed 0.2% lower at $354.11 and gained 0.22% to $355.60 in extended trading. **Benzinga Edge rankings** indicate Tesla’s stock has a Momentum score in the 13th percentile and a Growth score in the 41st percentile. **See More:Top Growth Stocks** ***Disclaimer*:** *This content was partially produced with the help of AI tools and was reviewed and published by Benzinga editors.* *Photo courtesy: IAB Studio on Shutterstock.com* ### Related Stocks - [MU.US](https://longbridge.com/en/quote/MU.US.md) - [TSLA.US](https://longbridge.com/en/quote/TSLA.US.md) - [CRSH.US](https://longbridge.com/en/quote/CRSH.US.md) - [MUD.US](https://longbridge.com/en/quote/MUD.US.md) - [MULL.US](https://longbridge.com/en/quote/MULL.US.md) - [MUU.US](https://longbridge.com/en/quote/MUU.US.md) - [MUZ.US](https://longbridge.com/en/quote/MUZ.US.md) - [TESC.US](https://longbridge.com/en/quote/TESC.US.md) - [TESL.US](https://longbridge.com/en/quote/TESL.US.md) - [TEST.US](https://longbridge.com/en/quote/TEST.US.md) - [TLA.US](https://longbridge.com/en/quote/TLA.US.md) - [TSDD.US](https://longbridge.com/en/quote/TSDD.US.md) - [TSIB.US](https://longbridge.com/en/quote/TSIB.US.md) - [TSII.US](https://longbridge.com/en/quote/TSII.US.md) - [TSLG.US](https://longbridge.com/en/quote/TSLG.US.md) - [TSLI.US](https://longbridge.com/en/quote/TSLI.US.md) - [TSLL.US](https://longbridge.com/en/quote/TSLL.US.md) - [TSLO.US](https://longbridge.com/en/quote/TSLO.US.md) - [TSLP.US](https://longbridge.com/en/quote/TSLP.US.md) - [TSLQ.US](https://longbridge.com/en/quote/TSLQ.US.md) - [TSLR.US](https://longbridge.com/en/quote/TSLR.US.md) - [TSLS.US](https://longbridge.com/en/quote/TSLS.US.md) - [TSLT.US](https://longbridge.com/en/quote/TSLT.US.md) - [TSLV.US](https://longbridge.com/en/quote/TSLV.US.md) - [TSLW.US](https://longbridge.com/en/quote/TSLW.US.md) - [TSLY.US](https://longbridge.com/en/quote/TSLY.US.md) - [TSLZ.US](https://longbridge.com/en/quote/TSLZ.US.md) - [TSW.US](https://longbridge.com/en/quote/TSW.US.md) - [TSYY.US](https://longbridge.com/en/quote/TSYY.US.md) - [TYYY.US](https://longbridge.com/en/quote/TYYY.US.md) - [07766.HK](https://longbridge.com/en/quote/07766.HK.md) - [09366.HK](https://longbridge.com/en/quote/09366.HK.md) - [TSL.US](https://longbridge.com/en/quote/TSL.US.md) - [SOXL.US](https://longbridge.com/en/quote/SOXL.US.md) ## Related News & Research - [Tesla cuts AI5 memory for Optimus, but not as much as originally planned](https://longbridge.com/en/news/300808438.md) - [Tesla sales beat Wall Street's expectations](https://longbridge.com/en/news/300795983.md) - [One year later, Tesla and Musk are still don’t have a good definition of ‘abundance’](https://longbridge.com/en/news/300704443.md) - [Former Tesla President Says Car Sales Are Funding the Longer Road to Robots and Cybercabs](https://longbridge.com/en/news/300821771.md) - [Micron Says Humanoid Robots Could Be Next Big Memory Driver, Analyst Sees 'Millions Of Machines' With Server-Level Chips](https://longbridge.com/en/news/300642773.md) --- > **Disclaimer: This article is for reference only and does not constitute any investment advice.**
