Where does the bug appear (feature/product)?

Cursor CLI

Describe the Bug

Can’t choose subagent model. Task tool only whitelists “composer-2.5-fast”.

Steps to Reproduce

Ask “what models I can use in Task tool?” or create a subagent with specified model and ask what model it is using in the prompt.

Expected Behavior

Should support all models

Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

This is a known limitation with the CLI specifically. The Task tool’s model parameter currently only exposes composer-2.5-fast for CLI users, regardless of plan type. Our CLI team is actively working on expanding model selection for subagents.

In the meantime, try omitting the model parameter entirely when dispatching subagents - this should let the subagent inherit the parent model. It won’t let you pick a specific different model, but it avoids being stuck on the fast tier.

No ETA to share, but this is being tracked and worked on.

This is not with the CLI specifically.

It’s with any consumer of the SDK, making any harness development of sufficient complexity almost useless. I have a discriminator model pick the model that needs to be used for downstream tasks. Works fine if I run the workflow through cursor/glass, totally broken in SDK because of this bug.

Can we get an ETA? I’m surprised this issue isn’t a more popular complaint.
