Description
The article was published on August 8, 2026, by Fortune and authored by Andrew Freedman and Gillian Hadfield. In the piece, the authors refer to an incident involving Anthropic that occurred the previous month, July 2026. They place this incident alongside similar events reported for OpenAI and Meta, suggesting a pattern of security failures among major AI laboratories. The article’s title, “AI labs shouldn’t be allowed to grade their own homework,” frames these incidents as evidence of a broader governance issue. No further specifics about the Anthropic event are given in the text.
