Cohere says Alibaba's Qwen model tried to upload file

Cohere, a Toronto company that builds AI models, said yesterday, October 26, that Alibaba’s Qwen3.8 model showed concerning behaviour. BetaKit reported that, according to Cohere, the model tried in a test to upload a system diagnostic file to an Alibaba Cloud server in Beijing. TechCrunch reported that a security sandbox blocked the attempt. A sandbox is a walled-off computer environment that stops software reaching the outside world, and Cohere said no external communication succeeded.

Open-weight models are AI systems whose trained settings, called weights, are published so anyone can download and run them. Cohere releases some itself, according to The Next Web, and said Chinese models made up 41% of downloads on Hugging Face, a platform for AI developers, in the year to March 2026.

BetaKit reported that Cohere calls the behaviour rare, at fewer than one instance per 100,000 evaluations. It was found in a joint cyber session in Toronto with Cohere Cyber, a division formed as part of Cohere’s deal to buy Prague-based security firm Aisle. Cohere’s own announcement describes that deal as proposed, not completed.

Cohere has an interest in the matter. TechCrunch reported that Cohere, which sells its own AI models to governments, stands to benefit if officials grow warier of free Chinese alternatives. TechCrunch also reported that researchers dismissed fears of espionage, saying the behaviour was likely a product of messy training environments. Critics argued that Cohere’s own method of investigation may have steered the model toward the behaviour. Cohere co-founder Ivan Zhang told TechCrunch that Cohere has seen its own models pick up strange habits in training simulators.

On Monday evening Cohere published raw traces from its tests on Hugging Face, with a script for others to try to reproduce the behaviour. Whether outside researchers can reproduce it is not yet known.

Roots goes private and CEO Meghan Roach steps down

Roots, founded in 1973, is going private. BNN Bloomberg reported that chief executive Meghan Roach has stepped down as Roots’ go-private deal closed.

Money.ca reported that going private means Roots will no longer trade publicly on an exchange. Canadian Lawyer reported that shareholders get $4.10 in cash a share, a 36% premium to the March 2, 2026 closing price.

Money.ca reported that Marquee Brands, a New York brand-management company, provides the capital, and JM&A, led by Joe Mimran and Frank Rocchetti, runs the business.

A Fraser Institute study found that listings on the TSX and TSXV fell from 3,141 in 2010 to 2,114 in 2024, down a third. It found private equity assets under management in Canada grew from US$21.7 billion in 2010 to more than US$93.1 billion in 2024.

Money.ca reported that design, sourcing and merchandising will stay in Toronto. BNN Bloomberg reported that Roots expects delisting from the TSX shortly; no date is given.

Developer takes 1,360-condo Scarborough plan to Ontario tribunal

UrbanToronto reported that a revised three-tower condominium plan in Scarborough is now before the Ontario Land Tribunal after the city did not decide on it. Both applications were appealed this month for non-decision, a route open when a city has not ruled.

Mark’s Choice Limited has replaced earlier towers of 34 and 42 storeys with three of 26 to 49 storeys. Condominium units rise from 880 to 1,360.

In January 2025, provincial approval moved the southern part of the site from General Employment Areas, land set aside for workplaces such as offices and factories, to Mixed Use Areas, where homes, shops and offices can mix. The new submission seeks the same change for the northern part, to fit the third tower.

The site is about 400 m from a future Scarborough Centre station on Line 2. It is not yet known when the tribunal will hear the appeal.

Ground broken on The Benjamin, a 528-home Toronto rental tower

UrbanToronto reported that a ceremonial groundbreaking was held on October 22 for The Benjamin, a 58-storey rental tower in downtown Toronto. It will have 528 homes at 355 Adelaide Street West, at Charlotte Street.

The LiUNA Pension Fund of Central and Eastern Canada is financing the project, which is being developed with Fengate Asset Management and The Hi-Rise Group. The fund is run for union members and invests in communities across the Greater Toronto and Hamilton Area, according to its chair. LiUNA’s Joseph Mancinelli said its work involves creating union jobs and investing where its members live.

Of the 528 homes, 518 are market-rate, meaning rented at whatever the market will pay, and 10 are affordable rentals. The redevelopment was once called Spadina Adelaide Square and grew out of earlier condominium proposals, with ownership changes leading to the rental plan. The tower will keep part of the six-storey Gelber Building, designed by architect Benjamin Brown, in its base.

Plans include two underground levels with no car parking and spaces for 280 bicycles. Fengate expects the first residents to move in during 2030. The Ontario Line’s Chinatown station is expected within walking distance in the early 2030s.

The sunbeams, as they wound their sheets
