The short version

  • Only AutoGen has a free tier, so it costs nothing to try first.
  • Each has a real cost: AutoGen framework now in maintenance mode, no new features planned; Black Forest Labs open weights licensing tiers (Builder, Platform, Professional) do not list public prices, requiring sales contact for most volumes.
  • They diverge on capability: AutoGen covers Multi-agent orchestration, Black Forest Labs covers FLUX 3 image generation.
