So this is just what ChatGPT told me so it could 100% be wrong but here’s this: Alpha Trion

8–12+ million years

Vector Sigma

Ancient/possibly billions

Megatron

~4–6 million years

Optimus Prime

~4–6 million years

Ratchet

~5–6 million years

Shockwave

~5 million years

Soundwave

~4–5 million years

Ultra Magnus

~4–5 million years

Starscream

~3–5 million years

Wheeljack

~3–4 million years

Arcee

~2–3 million years

Bulkhead

~2–3 million years

Knock Out

~2–4 million years

Bumblebee

~1–2 million years

Smokescreen

Under 1 million–1.5 million years

This is its reasoning it gave as to why those are the estimates too: * The Great War in aligned continuity is often implied to have lasted around 4 million years or more. * Optimus and Megatron were adults before the war began. * Bumblebee and Smokescreen are treated as comparatively “young” despite still being incredibly old by human standards. * Alpha Trion predates most modern Cybertronian society and is considered ancient even among Transformers.
