DSPy Research
Treating prompt engineering as a machine-learning problem — modular, trainable LLM pipelines built and optimized with DSPy.
A hands-on exploration of DSPy, the Stanford framework that reframes LLM orchestration as a machine-learning workflow: instead of hand-tuning brittle prompt strings, you declare signatures, compose them into modules, and let DSPy's optimizers (teleprompters) compile the pipeline against a dataset and a metric. This repo collects the notebooks, diagrams, and reference papers used to evaluate that approach on real tasks — code generation/evaluation, company valuation, and multi-stage market analysis.

Why DSPy
Conventional prompt engineering is manual, brittle, and hard to reproduce or scale. DSPy turns the same goals into an optimization problem:
- Declarative signatures — describe what a step should do (
question -> valuation, date, raised), not the exact wording of the prompt. - Composable modules —
Predict,ChainOfThought,ReAct, retrieval (RAG) and custom modules snap together into larger programs. - Compilation / optimization — teleprompters such as
BootstrapFewShotandBootstrapFewShotWithRandomSearchautomatically bootstrap demonstrations and tune the program against a training set and an evaluation metric. - Built-in evaluation —
dspy.Evaluateruns a program over a dev set and scores it, so improvements are measured, not guessed.
The payoff: fewer manual iterations, reproducible pipelines, and measurable score gains before vs. after compilation.
Notebooks
Each notebook is a self-contained experiment. They share a common setup — an OpenAI LM
(gpt-3.5-turbo) plus a You.com retriever (YouRM) for grounding — and progressively
introduce evaluation, RAG, and compilation.
| Notebook | What it demonstrates |
|---|---|
notebooks/code-evaluation.ipynb | End-to-end code-generation pipeline on the HumanEval dataset. Uses a typed pydantic signature to emit valid Python, runs generated code through a sandboxed REPL with a timeout, defines a pass/fail metric, evaluates with dspy.Evaluate, then compiles the program with BootstrapFewShotWithRandomSearch and re-scores it. Includes a worked detour through JSON-escaping pitfalls in LM output. |
notebooks/company-valuation.ipynb | A company-valuation pipeline that retrieves funding facts and extracts structured fields (valuation, date, amount raised, round, VCs). Builds a custom AssessValuation LLM-as-judge metric, contrasts a plain Predict baseline against a RAG module, then compiles the RAG program with BootstrapFewShot to lift the score. |
notebooks/market-analyst.ipynb | A comparative market-analysis module that compares two companies across valuation, headcount, founding year, and public perception — the building block for the multi-stage architecture below. |
Supporting code:
notebooks/repl/code.py— a small process-isolated Python REPL (execute_code) with a timeout, used to safely run model-generated solutions.notebooks/code-samples.py,notebooks/test.py— scratch task/solution samples and a debug harness used while building the notebooks.
System designs
The diagrams below trace the progression from a naive pipeline to a composed, compiled multi-stage system.
 | 1 · Basic company analysis (no compilation). A straightforward declarative pipeline — inputs in, outputs out — with no automated optimization. The baseline. |
 | 2 · Compiled & optimized company analysis. The same pipeline after DSPy compilation: demonstrations and module parameters are tuned against a dataset and metric for better accuracy and efficiency. |
 | 3 · Composable multi-stage pipeline. A Company Researcher and Market Analyst are each compiled into reusable DSPy programs, wired together with fact retrieval, social-media (X) perspective, comparative analysis, and evaluator-based scoring. |
Additional reference diagrams (regular vs. compiled RAG, program composition) live in docs/.

Getting started
The notebooks call hosted APIs (OpenAI, You.com), so you'll need the corresponding keys.
git clone https://github.com/iliazlobin/dspy-research.git
cd dspy-research
# create an environment (conda or venv)
python -m venv .venv && source .venv/bin/activate
# DSPy and the data tooling used by the notebooks
pip install dspy datasets pydantic python-dotenv jupyter
# configure credentials
cp .env.example .env # then fill in OPENAI_API_KEY, YDC_API_KEY, etc.
jupyter notebook notebooks/code-evaluation.ipynb
