Tel Aviv company doubleAI, formally AA-I Technologies and led by Mobileye co-founder Amnon Shashua, unveiled Maxwell on 19 October 2026. It calls the system a "code execution model", a category it places between ordinary code and the silicon that runs it, and says Maxwell can speed up software and also produce mathematical proofs that the changes are correct. The Wall Street Journal broke the news.
“More hardware is being built, but the need for compute is rising faster than the ability to build GPUs and CPUs”

Maxwell works on the compiled binary rather than the source, so a customer does not have to touch their own code, and it runs on both GPUs and CPUs. The company says it can alter applications while they are live in production. Its showcase results include a rewrite of Nvidia's cuGraph library in March that made more than half the algorithms at least twice as fast, a 38x gain for pandas on the PDS-H benchmark, and double the video-generation speed of the LTX-2.5 world model.
Shashua says the difficult part was checking that rewritten code still behaves, and that doubleAI found a formal way to verify it. As a demonstration of the maths side, the company says an internal agent found a chess position with 63 checking moves, past a record of 60 that had stood for nearly fifty years. Earlier this month the same agent reported a new graph-theory result with a Lean proof file.
About doubleAI
doubleAI is the trading name of AA-I Technologies, which was registered in Jerusalem in August 2023 and works from Ramat Gan. Globes reported in May 2025 that it had been operating below the media radar.
At that point it described its goal as reasoning models that decide and carry out tasks like human experts, an approach founder Amnon Shashua calls Artificial Expert Intelligence.

The business case is the cost of compute. Renting H100 capacity on a one-year contract is up 60% in a year, according to SemiAnalysis figures cited by the Journal, and doubleAI plans to buy 1,000 Nvidia B300 Blackwell GPUs itself. It intends to sell Maxwell to enterprises that want to run AI on less hardware. SiliconANGLE puts its backing, from Nvidia, Dell and others, at about $220M, with a valuation reported above $1B.
