Microsoft AutoGen / AG2
Multi-agent conversation framework built around the GroupChat orchestration pattern.
Dimension breakdown
Score · confidenceMulti-agent conversation framework built around the GroupChat orchestration pattern. AutoGen v0.4 introduced a complete async, event-driven redesign across three layers (Core, AgentChat, Extensions) with OpenTelemetry observability.
Key viability caveat: Microsoft's original AutoGen repository is now in maintenance mode (2026, no new features). The active fork AG2 (ag2ai/ag2) is developed by the community and ships independently (v0.12.2, May 2026; path to v1.0 announced).
Microsoft's strategic successor is the new Microsoft Agent Framework, which merges Semantic Kernel and AutoGen into a unified stack with session state, type safety, middleware, telemetry, and graph workflows. This three-way fragmentation — maintenance-mode original, active community fork, and incoming successor framework — is the defining viability caveat for enterprise adoption.
Referenced alongside LangGraph and CrewAI in enterprise framework evaluations. Not yet internally tested; advancement to Assessed requires hands-on evaluation and clarity on which lineage the team would standardize on.

Status rationale
Detected. AutoGen is a widely-referenced multi-agent framework cited alongside LangGraph and CrewAI in enterprise evaluations, making it a coverage gap worth tracking.
Entry deferred until now because the three-way lineage split (maintenance-mode Microsoft AutoGen, active AG2 community fork, and incoming Microsoft Agent Framework successor) makes target-of-evaluation unclear. Viability is mid-baseline rather than above: despite Microsoft backing and broad enterprise awareness, the maintenance-mode original and pending supersession by a new framework introduce meaningful adoption risk.
No internal hands-on evaluation has been performed (handsOn=not_tested); this is the primary gate for any status advancement.
Movement triggers
Upgrade to Assessed if: (1) internal hands-on evaluation completed with documented pilot results AND (2) team selects a clear lineage (AG2 fork vs. Microsoft Agent Framework successor) to avoid standardizing on maintenance-mode AutoGen.
Downgrade risk: if the Microsoft Agent Framework supersedes both AutoGen and AG2 before internal evaluation occurs, re-evaluate under the successor entry.
