💡 Our Take
Choose DSPy if you want declarative single-agent or pipeline programs with automatic prompt tuning and a strong evaluation framework. Choose AutoGen if you're building conversational multi-agent systems where agents negotiate, debate, or collaborate through message passing — AutoGen's strength is in agent-to-agent interaction patterns rather than prompt optimization.
Microsoft AutoGen - Pros & Cons
Pros
- ✓MIT-licensed open source with active development
- ✓Backed by Microsoft Research with strong academic foundations
- ✓v0.4's async event-driven architecture enables scalable agent systems
- ✓Native cross-language support for Python and .NET
- ✓AutoGen Studio provides a no-code interface for rapid prototyping
- ✓Tight Azure AI Foundry integration for enterprise deployment
Cons
- ✗Microsoft's agent strategy is evolving; monitor official announcements for roadmap changes
- ✗v0.4 introduced major breaking changes from v0.2, requiring significant migration effort
- ✗Steep learning curve compared to simpler frameworks like CrewAI
- ✗AutoGen Studio is experimental and not production-ready
- ✗No commercial support tier outside of Azure AI Foundry
DSPy - Pros & Cons
Pros
- ✓Optimizers can lift accuracy double-digit percentage points without manual prompt iteration
- ✓Model-portable: recompile the same program against a cheaper model and prompts auto-adapt
- ✓Backed by Stanford NLP + Databricks; real production deployments at Replit, JetBlue, Databricks itself
Cons
- ✗Steeper learning curve than LangChain or Instructor — concepts like Signatures and Optimizers require new mental models
- ✗Optimization runs are token-expensive — budget for hundreds of API calls per optimizer pass
- ✗No managed observability or eval UI; pair with Langfuse, Phoenix, or Braintrust for production tracing
