What changed

The spawn_agent tool now takes an optional model parameter, so each subagent can run on a different model from its parent, and subagents can compact their context. GPT-6.1 Sol is available with your own OpenAI key, Grok 4.7 becomes the recommended default for the xAI providers, and OpenCode model lists are fetched live with deprecated models hidden.

Who it affects

Zed agent users running subagents or BYOK OpenAI, xAI or OpenCode models.

What to do

Update to 1.22.0 and route routine subagents to cheaper models to save tokens.
