Multiagents setups can use 20x API tokens.

Cheaper model API is the only visible future for agents.

There's a question on whether to build a Single vs Multi-Agent System? @cognition_labs says don't build multi-agents. @AnthropicAI built a multi-agent system. 

@_philschmid found that is about the task you want to solve 'read' heavy  vs. 'write' heavy. 

Most of these tasks overlap, since you need sophisticated system that can be both read and write heavy, and adapt to future needs, multiagents systems is therefore better but here is a sidekick, multiagents system uses 15-20 times tokens, hence cost is something to worry about.
