Finding the right model Every model will perform differently across the operations within your AutoGen setup, such as speaker selection, coding, function calling, content creation, etc. On the whole, larger models (13B+) perform better with following directions and providing more cohesive responses.  Content creation can be performed by most models.  Fine-tuned models can be great for very specific tasks, such as function calling and coding.  Specific tasks, such as speaker selection in a Group Chat scenario, that require very accurate outputs can be a challenge with most open source/weight models. The use of chain-of-thought and/or few-shot prompting can help guide the LLM to provide the output in the format you want.
