How do you use subagents & multiple agent with local models, and how many?

A developer community discussion explores the practical application of subagents and multiple agents with local models. The user notes that running qwen3.8 27b nvfp4 on vllm with max context only supports about 8 agents, each with 32k context. This prompts a question about the common use cases where multi-agent frameworks are found to be beneficial and how other developers are utilizing them.
