Lumai secures over $10M for optical AI processing
Lumai, a UK AI optical processing startup spun out of the University of Oxford, has raised more than $10 million in investment. The round was led by Constructor Capital, with participation from existing investor IP Group and new investors including PhotonVentures, Journey Ventures, LIFTT, Qubits Ventures, State Farm Ventures, and TIS Inc. Lumai's technology uses optical beams to perform AI's core arithmetic operations in 3D space, bypassing the limitations of silicon GPUs. The company claims its PCIe form-factor solution can deliver 50 times the performance of silicon-only accelerators while using just 10% of the power, potentially lowering AI data center costs. CEO Tim Weil highlighted the unsustainable cost of current LLMs and the need for a radical computing shift. The investment will support product development, double headcount, and expand Lumai's US presence.
Funding for a startup developing optical computing for AI inference, which could reduce AI costs applicable to adtech and martech, though not yet industry-shifting.

OpenAI Expert: Optimize Token Efficiency for AI Agents
In an interview with t3n, Maximilian Hudlberger, Applied AI Engineer at OpenAI, explains that despite decreasing token prices, companies' AI costs can rise significantly, especially with the increasing use of AI agents. He argues that the true measure of cost-effectiveness is not the price per token, but rather the number of tasks completed with a given budget. Unnecessary costs often arise from using the most powerful model for every task, when simpler models would suffice. Businesses should therefore think in terms of completed tasks and optimize their model selection for economic efficiency. The article highlights that the growing deployment of AI agents in enterprise workflows is driving up token consumption, making cost management a critical business factor.
Microsoft Unveils Hybrid Intelligence, Open-Weight AI, RTX Hardware
Microsoft is repositioning Windows as a platform for 'hybrid intelligence,' enabling AI agents to run locally on PCs or in the cloud. The company announced the general availability of Microsoft Execution Containers (MXC), which sandbox agent execution and control access to files and networks, with support from Codex, GitHub Copilot, OpenClaw, and others. New AI models, including Microsoft's MAI Code 1.1 Flash, Nvidia's Nemotron, and DeepSeek V4 Flash, will run locally on RTX Spark devices, including the Surface Laptop Ultra (available for pre-order at $2,599). Copilot is gaining access to local files and system actions on Copilot+ PCs, rolling out in the coming months. Microsoft is diversifying its AI partnerships beyond OpenAI, building its own models, and aiming to regain trust after past missteps by emphasizing security and on-device processing.
Dan Ives: AI buildout only in 3rd inning, top 5 plays
Veteran technology analyst Dan Ives of Yorkville Ives initiated coverage on nearly 50 tech companies, expressing a 'very bullish' stance on the AI sector. Ives believes the AI buildout is only in the '3rd inning of a 9-inning game' and that investors underestimate the $4 trillion spending wave over the next few years. His top five equity plays are Nvidia, Microsoft, Palantir, Apple, and CrowdStrike. Ives highlights the expansion of agentic AI, which increases the attack surface and drives cybersecurity budgets from 5% to 10% of IT budgets within three years. He also sees demand broadening for AI infrastructure beyond hyperscalers to sovereign AI programs and neoclouds. Lesser-known picks include cloud equipment provider Boost Run and autonomous delivery company Serve Robotics, with significant upside projections.
