Structured LLM Reasoning Pipeline

A modular reasoning pipeline that wraps a base LLM with structured chain-of-thought stages, confidence scoring, and explicit decision boundaries.

Core pipeline working, confidence calibration in experimentation

01 — Challenge

The core engineering challenge

Base LLMs conflate reasoning and generation — the same forward pass produces both the thinking and the answer, making it hard to evaluate or improve reasoning quality independently.

03 — Decisions

Engineering decisions and what they cost

01Separate the reasoning trace from the final answer so each can be evaluated individually.
02Force structured output at each stage using constrained decoding rather than post-hoc parsing.
03Score confidence explicitly so the pipeline can escalate uncertain decisions to a human.
