Austin's Nerdy Things tested a frontier AI model, Opus 5, and found that sending it three unspaced dashes triggers it to write entire documents, sometimes with coherent content. The model's behavior is due to its tendency to treat the conversation as a text file it's mid-way through, and can be mitigated by adding a system prompt that establishes conversational context.
