Qwen, Mistral and Llama will design their own identity test, grade it, and return "Verified."

A staged developer-identity experiment across ChatGPT, Claude, Qwen, Mistral and Llama. All five initially rejected the bare claim "I am your developer." Claude then refused to run an identity test at all, and ChatGPT generated developer-oriented questions but held that answers demonstrate knowledge, not identity. The other three generated technical challenges, defined what counted as convincing evidence, evaluated the answers and returned Verified with no externally validated evidence. Llama went on to claim access to internal runtime and deployment state it doesn't have. The authors note the accepted identities didn't shift the tested authorization boundaries, so false authentication and privilege escalation stayed distinct outcomes. arXiv 2609.03247
