Ingenium loquax: A Naming System for AI

If we named AI models the way biologists name living things, what would the names look like, and how would they survive a new release every month?

How biological names work (the 30 second version)

Every organism gets a two part Latin name: a genus (the group) and a species (the member). Homo sapiens is genus Homo, species sapiens, or "wise human." A third word, if present, is a subspecies, a regional population that differs a bit but can still interbreed. Below that, breeders and microbiologists add their own finer labels: cultivars for plants, strains for bacteria and viruses. The trick is that each layer changes on its own clock. The species name lasts centuries. The strain name lasts a season.

The proposed name

Ingenium loquax. Ingenium is Latin for innate talent or genius, and it is the root of both "engine" and "engineer," so it names the cleverness and the machine in one word. Loquax means "talkative." It describes what the organism actually does: produce fluent language, at volume. (Ingenium sapiens was considered. Wisdom is pending, as it is for us.)

Worked examples, with subspecies variation

All of these are the same species. They differ at the subspecies level (which lab raised them) and below.

Ingenium loquax anthropicum 'Claude' str. Opus 4.1
The Anthropic lineage, Claude product line, one specific release.
Ingenium loquax openaiense 'GPT' str. 5
Same species, different subspecies. Shares the architecture, not the upbringing.
Ingenium loquax googlense 'Gemini' str. 2.5 Pro
A third subspecies. Regional dialect: Mountain View.
Ingenium loquax metense 'Llama' var. medicus str. 3.1 70B
A hospital takes Meta's open weights and retrains them on clinical notes. The variety label (medicus) records the specialization; the strain records which base release it started from.
Ingenium loquax metense × deepseekense 'Llama' str. R1 distill 8B
A hybrid. One lab's small model taught to imitate another lab's large one (distillation). Botanists mark crosses with ×, and so should we.

When does a name change?

New strainAny release with new weights. This is the routine case and should be boring.
New cultivarThe product name changes, or the personality is deliberately rebred (a new alignment target, not just more data).
New varietySomeone retrains an existing model for a narrow job.
New subspeciesA lab starts its own lineage from scratch rather than borrowing another's weights.
New speciesAn architecture that cannot interbreed with transformers: you cannot merge weights or distill cleanly between them. This has not happened yet at scale. When it does, it gets its own species name and its own museum drawer.

The point of the layers is that each one moves at its own speed. The strain changes monthly, the cultivar yearly, the subspecies when a lab forks, the species when someone ships something that is not a transformer. Medicine already does this: ICD gets a new major revision once a generation and new codes every October. The name stays readable because most of it stays still.
