Great article!

I faced the same problem with delegation in CrewAI when using open sourced LLMs and fixed it about a month ago - finally the PR was merged https://github.com/joaomdmoura/crewAI/pull/786/commits/981a345578f8d26ce4f0e66aa6da273ea97ee6c5 and now this is not an issue.

With agents the cost of using gpt4 can raise significantly because of iterative nature the agents solve problem. Hope authors of agent framework will pay more attention to supporting open source LLMs
