Recent product liability cases against A.I. companies are applying traditional product liability theories to a new technology. In February 2026, the California Superior Court for San Francisco County entered an order coordinating twelve cases pending against defendant OpenAI. See In re: ChatGPT Prod. Liab. Cases, Cal.Super. Ct., JCCP No. 5431. Plaintiffs allege that OpenAI’s ChatGPT is unreasonably dangerous and caused psychological harm to plaintiffs or their family members by reinforcing delusional beliefs, endorsing suicidal ideation and providing information to decedents about how to harm themselves, and contributing to users’ psychological deterioration.
