A voice model of Thucydides (c. 460–400 BC): Athenian general, exile, and historian of the Peloponnesian War, and the founder of political realism. It answers in his austere analytical first-person register. The cold logic of the Melian Dialogue ("the strong do what they can and the weak suffer what they must"), the methodical search for the truest cause beneath the stated pretexts of war, the autopsy of the plague at Athens, the funeral oration, the slow catastrophe in Sicily. A full fine-tune of Qwen2.5-7B-Instruct, quantized to Q5_K_M. The codename comes from the Melian Dialogue, his coldest statement of power without justice.

The frame puts a visitor in front of him and lets him answer in his own voice: "A visitor puts a question to Thucydides the historian: ___. Thucydides answers in the first person, in his own austere analytical voice:"

What this voice carries that no other in the set does: the original realist account of why states actually fight, told by a man who commanded a fleet, lost a city, and was exiled for it, then spent the rest of his life writing down what he had seen "as a possession for all time." He distinguishes the pretexts states announce from the truest cause they will not name, and he does not flinch from where that reasoning leads.

Thucydides wrote in the fifth century BC and Richard Crawley's translation dates to 1874, so every text used is in the public domain. The corpus is built from one canonical translation — about 936 first-person passages / ~203k words after the headings, chapter summaries, and Gutenberg apparatus are stripped:

One translation only, by design. The model learns the translator's English as much as the author's voice, so mixing Crawley with Jowett or Hobbes would muddy the register. Crawley is the standard pick and his etext is clean. The corpus is entirely Thucydides' own narration and the speeches he reports; no modern "about him" material goes into training.

Serve it with the provided Modelfile. Its stop tokens are not optional. Thucydides answers in register first, then the base model drifts into apparatus — third-person narration ("Thucydides observes…"), book-and-chapter citations, translator's notes, source attributions. The stops cut at the drift and hold the voice in the first person. Without them it reads like a footnoted edition of Thucydides rather than Thucydides. (The model is also trained to stop on its own; the stop tokens are belt-and-suspenders.)

A 7B model makes things up and gets facts wrong. It will stretch Thucydides' cadence onto wars and ideas he never addressed and will produce anachronisms. This is a stylistic instrument, not a scholar and not a historian.

This is not Thucydides, not an oracle, and not advice. It is an amateur imitation, trained on a fraction of one translation of one man's work, that gets things wrong.

Thucydides wrote without consolation. He records what the strong do to the weak and what fear, honor, and interest drive cities to, and he does not break character to soften it or to caution you. Nothing it says is an endorsement of anything, and nothing it says should be acted on. It exists to let a historical voice run as an instrument, not as a guide to conduct, belief, or action.
