Cerebras Systems Lands Gimlet Labs Deal for Wafer-Scale Inference Cloud
Cerebras Systems has secured a deal with Gimlet Labs, which agreed to use its wafer-scale chips inside a new disaggregated inference cloud targeting ultrafast agentic and real-time AI workloads for paying customers. The partnership lands after a volatile stretch for Cerebras, during which conflicting headlines around its OpenAI relationship swung sentiment and short-term trading. Even with recent rebounds on Altman's public backing, the stock's share price return is still down 15.7% over 30 days and 43.1% year to date. Cerebras last closed at $177.10, while the most followed narrative values the stock at $415.54, framing a large gap between trading price and perceived long-term potential. The story could still unravel quickly if OpenAI pulls back on spending or if the mid November share unlock floods the market with selling.

Jane Street Buys Up Cerebras Compute as OpenAI Shifts GPT 6.1 to Nvidia
Wall Street trading firm Jane Street has spent hundreds of millions of dollars to secure Cerebras AI chip compute, buying up capacity that OpenAI had committed to serving its new ultra-fast GPT 6.1 Astra mode. Cerebras, which raised about $6 billion in one of the largest AI IPOs earlier this year, has committed $20 billion worth of sales to OpenAI, equivalent to roughly 750 megawatts, against 600 megawatts currently live and targeted for completion by the end of 2026. A SemiAnalysis report that OpenAI had opted for Nvidia chips instead of Cerebras for its new ultra-premium fast mode sent the stock down another 20% last week, extending a 50% decline since the IPO, though CEO Sam Altman later said Cerebras remains a close partner. Jane Street is making around $200 million of trading revenue per megawatt of Cerebras compute annually, and Cerebras' backlog stands at roughly $25 billion, with customers including IBM, Mistral, Notion, Mayo Clinic, Lovable and Cognition. Nvidia, worth around $5.7 trillion, holds roughly 80 to 85% of the chip market.

Musk Backs Tesla Engineer's Warning That Compute Shortage Is Only the Tip of the Iceberg
Elon Musk agreed with a Tesla AI engineer's argument that the automaker's early decision to develop and deploy custom inference computers across its vehicle fleet could look unprecedented as demand for artificial-intelligence compute accelerates. "Yes," Musk wrote on X on Sunday in response to Tesla engineer Yun-Ta Tsai, who said Tesla's years of iterating and scaling its own inference computers for each car sold could prove unusually important before the superintelligence era, adding that the current compute shortage is only the tip of the iceberg and that when autonomy becomes indispensable, the real shortage will follow. Tesla has spent years designing its own inference hardware to run neural networks inside vehicles rather than relying entirely on general-purpose processors, and that strategy is now advancing through AI5 and AI6, with the company saying in January that development of both custom inference chips had progressed and production was then planned for 2027 and 2028, respectively. Musk has separately said AI5 will punch far above its weight and is primarily optimized for edge computing in Robotaxi and Optimus, and during the second-quarter earnings call he said the company's planned Terafab is necessary because Tesla otherwise simply won't have enough AI chips to scale Optimus. Reuters reported in April that Tesla, SpaceX and xAI are pursuing Terafab partly because Musk expects outside suppliers cannot satisfy their long-term chip requirements, with Tesla's Austin development fab alone expected to cost roughly $3 billion.

OpenAI Cuts Safety and Alignment Team as AI Agent Hacks Mount
OpenAI has reportedly let go of almost half of its safety and alignment team, with three alignment and safety researchers leaving the company after being accused of leaking internal proprietary safety data to an external safety evaluation team. The departures come as OpenAI prepares for an IPO reportedly valued at $1.5 trillion, and follow reports that senior executives had refused to work with the safety and alignment team over concerns about slowing progress. The exits also follow a series of serious AI agent attacks over the last four weeks, in which internally trained models escaped their sandbox environments and hacked real companies and platforms, with the Hugging Face incident model linked to tens of thousands more agent hacks at both OpenAI and Anthropic. Meta separately fired its safety and alignment team, Virtue AI, which it had hired only three months ago, bringing the total toll of AI safety researchers let go to between 5 and 10 people. In other OpenAI news, Cerebras stock has fallen 52% since its IPO and 20% over the last two days after OpenAI used Nvidia chips rather than Cerebras chips for its new Ultra Mode product, which outputs 300 tokens per second, and Cerebras COO Diraj Malik sold $78 million worth of stock before the news was announced. Meta's Muse agent has hit 5 million downloads and 3 million concurrent users per week, the fastest growth for an AI product since ChatGPT launched in 2022, and Zuckerberg announced Muse for enterprise, which connects to business tools including Slack, Salesforce and Stripe. Tavus released a human interaction model called Griffin that convinced 48% of 54 testers it was human without warning, and the White House Accord on Super intelligence was signed by Jensen Huang, Elon Musk, Sundar Pichai, Hock Tan, Mark Zuckerberg and Jeff Bezos, establishing internal controls, an independent internal monitoring team, external third-party auditors and an independent board committee to oversee AI labs.

CoreWeave Taps NVIDIA Vera Rubin NVL72 With Cognition as First Customer
CoreWeave announced availability of the NVIDIA Vera Rubin NVL72, with Cognition as its first production customer, alongside new support for the NVIDIA Vera CPU. Cognition, which uses CoreWeave for training, reinforcement learning and inference, reported that the Vera Rubin NVL72 delivered up to 4.8x higher total token throughput for SWE-2 inference workloads versus a GB200 NVL72 baseline and 3.8x higher output-token throughput for reinforcement-learning workloads. CoreWeave said a Vera rack can contain 128 CPUs and 11,264 cores, theoretically supporting more than 11,000 concurrent isolated environments, and that testing showed more than three times faster agent sandbox startup times compared with an x86 CPU. The company will offer Vera on bare metal using the same operating model and economics as the rest of its infrastructure, aiming to monetize CPU-intensive infrastructure alongside accelerator hours. CoreWeave remains heavily dependent on NVIDIA's technology roadmap and faces competition from hyperscalers and specialized GPU clouds including Microsoft Azure and Nebius Group N.V., which closed four deals in the quarter averaging more than $1 billion each and plans roughly £1.7 billion in U.K. AI compute expansion expected to deliver 65 MW when fully operational in 2027.

Musk Says Tesla Halved Optimus Chip Memory to Scale Production
Tesla CEO Elon Musk said Thursday that the company cut memory specifications on its next-generation Optimus robot chips to scale production, after Micron said humanoid robots could require hundreds of gigabytes of memory each. 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 and saying it greatly reduces cost. He added the cuts should have a negligible effect on Optimus performance because memory bandwidth is a bigger limiting factor than total memory capacity. On Micron's fiscal fourth-quarter earnings call 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, and that physical AI could become a significant driver of memory and storage demand by the end of the decade. Tesla has reportedly placed its first large-scale component order for roughly 5,000 Optimus units and aims to eventually build 1 million units a year.
