Evaluation pipeline

As explained in Build a Reasoning Model (From Scratch)

An ordered process that loads a model, generates outputs, and scores them against a dataset or reference answers.

An evaluation pipeline quantitatively tests a model across many examples: load a pretrained model, generate outputs, and score them against a dataset or reference answers. section 3.0

A practical pipeline proceeds through these stages:

  • Load the pretrained model and evaluation data. section 3.0
  • Generate an output for each problem. section 3.0
  • Extract the final answer reliably from each response. section 3.0
  • Verify correctness by comparing the output with the reference solution, using a symbolic math solver when appropriate. section 3.0
  • Aggregate scores to distinguish convincing responses from correct solutions. section 3.0

Math-problem evaluation

Run a pretrained model over a set of math problems, extract each final answer, and compare it with the reference solution through a calculator-like symbolic verifier. The resulting scores measure accurate problem solving rather than persuasive wording. section 3.0

How Build a Reasoning Model (From Scratch) covers it

How deep it goes
Explains the end-to-end workflow and answer verification, but does not specify implementation code or scoring formulas.
Examples
Uses math problems, generated final answers, reference solutions, and calculator-like symbolic verification as concrete evaluation artifacts.
What it assumes
Assumes access to a pretrained model and evaluation dataset while introducing answer extraction and reference-based verification.
What you can do after
Evaluate model accuracy quantitatively and distinguish correct solutions from merely convincing responses.
How it connects
Connects model evaluation with answer extraction, symbolic math solvers, reference answers, and verifiable rewards.
