Engineering teams wanting an open-source, model-agnostic framework
Enterprises scaling AI agents into production
Teams already running AutoGen in production
Researchers studying multi-agent systems
Developers prototyping agent collaboration
ML and NLP engineers
Researchers building RAG systems
Teams wanting reproducible LLM pipelines
Pros
The open-source core gives developers full programmatic control over agent roles, tasks, tools, and orchestration logic, with no vendor lock-in on the framework itself.
A dual interface serves both audiences well: a CLI and Python framework for engineers, plus a visual editor with an AI copilot that lets less technical builders assemble workflows without code.
Its model-agnostic, bring-your-own-key design lets teams choose whichever LLM provider best fits their cost, latency, and quality requirements rather than being tied to one vendor.
The role-and-task orchestration model maps cleanly onto real multi-step processes, making it straightforward to build research, writing, and review pipelines where agents hand off work.
The enterprise tier adds production-grade needs like private infrastructure deployment, on-site support and training, and dedicated development hours for organizations scaling agents.

Cons
Pricing predictability is weak above the free tier: the jump from 50 executions per month to custom enterprise contracts leaves little middle ground, and negotiated deals can be expensive.
Total cost is harder to forecast because LLM API usage is billed separately through your own provider keys and often becomes the largest expense.
Building reliable multi-agent systems carries a real learning curve, and orchestrating many agents can introduce latency and performance concerns as workflows grow in complexity.
As agent count and execution volume scale, teams may hit throughput ceilings that require careful tuning or an upgrade to higher enterprise tiers.
In maintenance mode as of 2026, no new feature focus
Microsoft steers new projects to the Agent Framework
Multiple version lines (0.2 vs 0.4/0.7) cause confusion
Multi-agent loops can be hard to control and cost-predict
Less enterprise tooling than the successor framework
Steeper conceptual learning curve
Python-only
Optimization runs can be compute-intensive
Less suited to simple single prompts
Requires defining good metrics
