OpenAI said it considered contacting Canadian police about an account later linked to a deadly school shooting.
The company flagged the profile in June for the “furtherance of violent activities”.
The user was later identified as Jesse Van Rootselaar, who killed eight people in British Columbia before taking his own life.
The attack is among Canada’s worst in recent years.
OpenAI reviewed whether to notify the Royal Canadian Mounted Police.
It decided the activity did not show an imminent or credible threat of serious harm at the time.
The company said that threshold guides all law-enforcement referrals.
After the shooting, OpenAI proactively shared information with investigators.
It said it will continue to support the inquiry.
Police reported the attacker first killed family members at home and then targeted a nearby school.
Victims included a teaching assistant and five students aged 12 to 13.
The motive remains unclear.
The case has intensified debate over how technology companies identify and report potential threats.
