OpenAI said it considered contacting Canadian police about a user later responsible for a deadly school shooting.
The company flagged the account in June for potential “furtherance of violent activities”.
The suspect, Jesse Van Rootselaar, killed eight people in British Columbia before taking their own life.
The attack is one of the worst school shootings in Canada’s recent history.
OpenAI reviewed whether to alert the Royal Canadian Mounted Police.
It decided the activity did not show an imminent or credible threat at the time.
The company said referrals require clear evidence of serious and immediate risk.
After the shooting, OpenAI contacted the RCMP and shared account information.
Police said the suspect first killed family members at home before attacking a local school.
Several victims were students aged 12 and 13.
The motive remains unclear.
The case has intensified debate over when technology companies should inform law enforcement about threatening behaviour.
