I'm obsessed right now with figuring out the right patterns for LLM subagents.
I think that all software we write is going to have a lot of inference loops running all the time!
A big driver for this is that human-in-the-loop processes must be fast and non-blocking. (Think about voice interfaces, for example.) These human-in-the-loop LLM ... um, loops ... also need to start, stop, steer, and share context with longer running tasks that require external resources, need to use bigger/slower models, etc.
We've been hacking on a bunch of subagent abstraction experiments in Pipecat.
One thing we need is good ways to run subagents both locally and remotely. Enter @vercel sandboxes!
Gradient Bang is our big, open source, multi-player LLM game. It's a canvas for experimenting with subagents, very long contexts over many sessions, dynamic user interfaces, and voice.
@jonptaylor just added "bring your own subagents" support to Gradient Bang, built on Vercel sandboxes.
Here's his video walk-through.
