Definition. Base-model artifact [ftip-001K]
A base-model artifact is an executable tuple \[ M_0=(\tau ,\delta ,\mathsf {cfg},\theta _K,\mathsf {num}), \] where \(\tau ,\delta \) are the tokenizer and detokenizer of Definition [ftip-000E]; \(\mathsf {cfg}\) fixes the architecture of Definition [ftip-0012]; \(\theta _K\) is the stopped pretraining checkpoint; and \(\mathsf {num}\) fixes the numerical and inference conventions required to evaluate its next-token law.
The tokenizer model is part of the executable system by Definition [ftip-000E]. A weight file without its vocabulary, architecture configuration, or output convention does not determine the law \(\pi _{\theta _K}\) in Definition [ftip-000H]. Training-data and optimizer provenance may accompany the artifact, but they are not runtime inputs.
