OpenAI has revealed it debated alerting Canadian authorities about a user months before a deadly school attack.
The company said it flagged the account of Jesse Van Rootselaar in June for activity linked to potential violence.
After reviewing the case, OpenAI decided the threshold for contacting law enforcement was not met.
Its policy requires signs of a credible and imminent threat of serious harm.
The company said it found no evidence of active planning at the time.
The 18-year-old later killed eight people in Tumbler Ridge in British Columbia before taking their own life.
Police said the victims included a teaching assistant and several students aged 12 to 13.
The attacker had previous mental-health-related contact with authorities.
Following the shooting, OpenAI contacted the Royal Canadian Mounted Police and shared information about the account.
The company said it would continue to support the investigation.
The motive for the attack remains unclear.
The incident is Canada’s deadliest mass killing since the 2020 Nova Scotia shootings.
