Consider using different models for different agents

[bmwttd]

All the agents use the same model as part of the create_graph function / method.

In some cases you would want to use different models for different agents. For example, openai model for the planner agent and claude for the reviewer. The setup is such that all the agents are configured using one model type. Passing a dictionary to the create_graph method to override the default model per node or using a config file per agent would be useful.
