Made for the way you work
Subagents and side threads
Give separate parts of the work focused attention. Keep the main chat responsible for bringing the result together.
In practice
A useful place to start
Have a writer implement a bounded change while a reviewer checks its callers. Use a side thread to explore a question without filling the main conversation with every detail.
Roles that fit the work
Built-in profiles cover writing, review, evidence gathering, and broader design. Custom agents can define their own purpose, instructions, model choice, and tool access.
Stay in touch
The main agent can inspect progress, send messages, collect results, and stop work. You can see child activity and open the related chat to inspect its evidence.
Choose the right model
Pin a model for a specialist or allow an automatic choice. Profiles let you put different levels of capability behind routine work and difficult questions.
Get started
Ask the agent to split a large task into clear, bounded parts. Review or customize the available agents in Settings.
Good to know
Parallel agents use resources and can incur separate model charges. They may share files, so overlapping edits need coordination. A second agent's answer still needs evidence.
