What variant of Codex are you using?

Codex CLI

What feature would you like to see?

I would like to see MAX_THREADS be a variable in the CONFIG file so we can run more than 6 subagents at one time.

I have a forked Codex which I'm using to launch more than 6 subagents at a time. It works amazing. I think having 6 default is reasonable, but some of us want more. Please make MAX_THREADS a variable that you can set inside the CONFIG.TOML

My fork allowed for custom subagents, but @jif-oai is a legend and added that for us, so the only thing left I need is more agents.

I built an app in 7 minutes with Spark using 12 parallel agents. This will unlock blistering speed for power users. Please make it so <3

Thank you so much Codex team.

The agents.max_threads config key allows you to configure this value. If you don't specify the config key, it defaults to DEFAULT_AGENT_MAX_THREADS (6).

@etraut-openai you're a legend.

Note that if you go significantly above 6, you might trigger a 429 error. That's why we decided to cap it to 6 by default.

Thank you so much for that. This is going to make a lot of people happy. I get this comment on X almost every day. And I myself am going to use this a ton. Thank you kindly!
