# 0.3.9

> Run Codex on Cogno credits, let agents use the apps on your Mac, and switch between Codex accounts.

## TL;DR

## Codex on Cogno credits

Business workspaces with [Cogno credits](https://cogno.studio/docs/billing.md#review-cogno-credits) can run Codex without anyone's own Codex sign-in. The model picker lists **Codex** with the Cogno mark first, above **Claude Code** and your own **Codex**, and its one model is **Optimized model**. It runs on this computer and in Cloud.

* Credits pay for Codex only. Claude always uses a member's own Claude account.
* A conversation keeps the agent it started on. Picking another agent's model starts a new conversation in the same working copy.
* **Settings → Billing** shows what is left, what has been used, every run that used credits, and when the earliest credits expire. Credits expire 6 months after they are granted.
* Credit runs are processed on Amazon Bedrock and may be processed outside Japan. Every Business purchase screen says so next to its button.

## Computer use on your Mac

Cogno Desktop now includes [computer use](https://cogno.studio/docs/agents.md#computer-use-on-your-mac) on Apple silicon Macs. Agents running on that Mac can read windows, click and type in its apps without an extra install, and they do not take over your pointer. Cogno needs **Accessibility** and **Screen Recording** under **System Settings → Privacy & Security**.

When an agent clicks, a faint ripple marks the spot. To watch a cursor instead, choose **Black** or **Silver** under **Settings → Preferences → Computer use**.

## More than one Codex account

Add separate Codex sign-ins on a computer and choose one for each Task. See [Choose a Codex account](https://cogno.studio/docs/agents.md#choose-a-codex-account-on-your-mac). Claude and Codex accounts can now also be switched in the Windows and Linux Desktop apps.

## Also in this release

* On a Mac with a notch, a new question or approval addressed to you opens on its own, even when the Task belongs to someone else.
* Onboarding sets up this computer first, then Cloud, and connects an agent account straight from its button.
* While you type an invite, the preview shows each teammate with a pixel icon.
* Closing the chat no longer overlaps the Actions tab and the Task name.
