priorstudio-core 0.4.0

Core abstractions for PriorStudio — Prior, Model, Eval, Run, and the block registry.

priorstudio-core

The Python contract for PriorStudio FM projects.

from priorstudio_core import Prior, Model, Eval, Run, register_block, register_prior

@register_prior("my_prior")
class MyPrior(Prior):
    def sample(self, seed: int): ...

@register_block("my_attention")
class MyAttention:
    def __init__(self, d_model: int, n_heads: int): ...

The CLI discovers anything registered via these decorators and validates models/*.yaml references against the registry.

Layout

• prior.py — Prior ABC and built-in prior loader
• model.py — Model config + block-composition
• eval.py — Eval config + result schema
• run.py — Run manifest + executor protocol
• registry.py — @register_prior, @register_block, @register_eval and discovery
• loaders.py — load YAML artifacts into typed objects
• blocks/ — built-in architecture blocks (transformer encoder, causal attention, heads)
• training/ — minimal in-process training loop for the local compute adapter
