Not just RL on tool calling, but RL on agent orchestration, neat!

1,500 tool calls per task sounds like a nightmare for unit economics though. I've been optimizing my own agent workflows and even a few dozen steps makes it hard to keep margins positive, so I'm not sure how this is viable for anyone not burning VC cash.

"tool call" is just a reference to any elementary interaction with the outside system. It's not calling third-party APIs or anything like that.

True, but that's still 1,500 inference cycles. Even without external API fees, the latency and compute burden seems huge. I don't see how the economics work there without significant subsidies.

FWIW many tool calls can be and often are made in one inference cycle.

Is this within the model? Or within the IDE/service that runs the model?

Because tool calling is mostly just the agent outputting "call tool X", and the IDE does it and returns the data back to AI's context

An LLM model only outputs tokens, so this could be seen as an extension of tool calling where it has trained on the knowledge and use-cases for "tool-calling" itself as a sub-agent.

Ok, so agent swarm = tool calling where the tool is a LLM call and the argument is the prompt

Yes largely, although they’ve trained a model specifically for this task rather than using the base model and a bit of prompting.

Sort of. It’s not necessarily a single call. In the general case it would be spinning up a long-running agent with various kinds of configuration — prompts, but also coding environment and which tools are available to it — like subagents in Claude Code.

Parallel agents are such a simple, yet powerful hack. Using it in Claude Code with TeammateTool and getting lots of good results!
