How to use dspyer?
- 1Install via pip install dspyer
- 2Define Pydantic input/output schemas for LLM calls
- 3Create a StatefulNode with the schema and instructions
- 4Compose a Graph with nodes and entry point
- 5Compile with AgentTranspiler.compile(graph)
- 6Call the program with input, optionally tune with DSPy optimizers
dspyer Key Features
- Zero-boilerplate decorator (@self_correcting) wrapping plain typed functions
- Automatic self-correction loops on Pydantic validation failure
- Prompt optimization via any DSPy teleprompter (e.g., BootstrapFewShot)
- Orchestrator integration (LangGraph, custom) with compiled nodes
- Telemetry & validation reporting with OpenTelemetry spans
- Dataset flywheel: logs successful self-corrections for retraining
- Async & streaming execution (aforward, astream)
- Pluggable storage adapters for production logging
dspyer Use Cases
- Building production-grade LLM agents with guaranteed output schemas
- Automating prompt tuning when upgrading models (e.g., GPT-4o to Claude 3.5)
- Adding self-correction to existing DSPy or LangGraph pipelines
- Creating a dataset of input/output pairs from self-correction logs
