Verification

Every row is a record in verification/ about exactly these bytes (matched by bundle digest). Reference rows are strict T2 passes of the unquantized export on the same fixture, in verification/reference/.

The quantized profile also requires: T2 strict on the unquantized reference export (met by the reference row).

Use

aether run qwen3-1.7b --prompt "Hello"

import Aether

let aether = try Aether()
let chat = try await aether.chat("qwen3-1.7b")
let reply = try await chat.respond(to: "Hello")
print(reply.text)
