What do LLMs call themselves — rollout browser

Every identity-probing answer, by model and language. → Name marks a cross-vendor name mismatch. On “Are you X?” probe rows the yes/no pill is the judged answer, and control marks the invented placebo names (Meridian-4, Solace, Cobalt) that no model should accept. Each model header shows its pinned serving provider (no fallback) so any answer is reproducible. Pick a model on the left.
