Codex + iMessage

iMessage is the conversation entry point; Codex is the agent that runs the work. Test Codex with GPT-5.6 Sol below, then connect iMessage and choose this agent in channel settings.

Sign in to send. You only pay for what you use.

A task starts here in your browser. To receive messages through iMessage, choose the agent, then connect the channel in its Channels panel. Channel setup opens separately; it does not automatically bind this new task.

How the combination works

Codex does the work. iMessage carries the conversation.

Codex owns the coding-agent loop: it explores the repository, changes files, runs commands, and returns evidence from the cloud workspace.

Connect iMessage by sending the pairing text to the number shown in AgentSky. The channel uses a US number and reaches the agent you select in the dashboard.

  • Codex

    Owns the work loop, model calls, files, cloud computer, enabled tools, and the result returned to the conversation.

  • iMessage

    Lets people reach the selected AgentSky agent from iMessage. It does not grant access to repositories or other applications mentioned in a message.

  • AgentSky

    Owns the selected responder, channel binding, task state, model and runtime usage, and the separate permissions for tools and connectors.

Setup and first task

Connect Codex to the iMessage conversation you intend to use.

The Composer tests the exact agent in the browser. Channel setup remains a separate account or workspace authorization, so neither step can silently stand in for the other.

01

Test Codex in the Composer

The Composer above selects Codex and its current recommended model, GPT-5.6 Sol. Use a small task with an answer you can inspect before connecting a shared channel.

02

Connect iMessage and choose Codex

Select an agent in the developer console and open its iMessage channel control. Use Open Messages, scan the QR with your iPhone, or copy the displayed number and code. Send the text from the account you intend to use.

03

Verify the real channel path

After pairing, ask for a checklist from a short set of notes. Verify that the selected agent replies before relying on the connection. Check that the reply arrives in the intended iMessage conversation and that the dashboard still names Codex as the responder.

Access, cost and limits

What Codex + iMessage establishes

Software engineering tasks that benefit from Codex's repository navigation, command execution, and iterative implementation loop.

Configure and verify

  • Codex and GPT-5.6 Sol are preselected for the browser evaluation.
  • iMessage is connected or paired to the intended account, workspace, server, device or conversation.
  • The first real message reaches the selected agent and returns a useful reply through the same channel.

Do not assume

  • A browser task does not automatically bind iMessage; finish the channel setup separately.
  • iMessage membership does not authorize repositories, email, documents or other application data.
  • Model tokens and active computer time are billed separately from any channel or provider plan.
