Codex in Continuum

Same Codex runtime. Continuum adds multi-lab peers, mobile, and repo-level cost truth.

Codex is OpenAI’s coding agent (CLI + app-server). Continuum is the multi-provider control plane that runs Codex as a first-class agent - next to Claude Code - with worktrees, phone control, multi-account CODEX_HOME isolation, and a spend ledger. Continuum does not replace Codex; it hosts it. Live Codex chat in Continuum uses the ACP harness on Codex app-server - the old JSONL-only chat path is not the live path. That matters when you care about tools, turn state, and completion signals.

Choose Continuum when

You want Codex plus Claude (and friends), gauges for every account, mobile approve, and one Code tab - not a single-vendor silo.

Choose Codex when

You only want OpenAI’s native Codex experience and are happy living inside that product surface alone.

In Continuum

Codex in a multi-lab day

09:30

Spawn a Codex session in Continuum’s Code tab. Transcript, plan, and terminal panes attach to the same thread.

11:00

Open a Claude session on the same prompt in another worktree. Compare diffs side by side and keep the stronger branch.

15:45

Secondary CODEX_HOME for work stays isolated from personal auth. Analytics attributes both to the right provider column. Night batch pins work CODEX_HOME; personal primary stays untouched for morning ChatGPT/Codex use outside Continuum if you want.

In Codex

Native Codex only

09:30

Use Codex’s own CLI or app-server surfaces. Full OpenAI agent quality, OpenAI-only world.

11:00

Stay on Codex for the next prompt. Comparing to Claude means leaving the product.

15:45

Default auth is one home. Multi-login isolation and Continuum mobile pair are outside this path. Native Codex is enough when you never need Claude peers or Continuum mobile.

02 · Monday path

Monday with Codex in Continuum’s Code tab

Install, connect, first session - steps you can run the same day.

01

Install Continuum; confirm `codex` login works (or secondary CODEX_HOME auth.json for work account).

02

Code tab → new session → Codex → worktree for the ticket; panes attach (chat, plan, diff, PR, terminal).

03

Open a Claude peer session on the same repo when you want a second branch of attack - compare diffs at review.

04

Pair iPhone; approve or interrupt while Codex runs on the Mac host.

05

Check Usage analytics for Codex history by repo; live gauges cover accounts Continuum can poll.

06

Night batch: pin work CODEX_HOME so personal auth never gets stomped.

07

Verify `codex` auth.json for any secondary instance before kicking a long ACP session - fail-closed beats wrong-account surprises.

How Continuum actually runs Codex

How Continuum actually runs Codex

  • Live Codex chat uses Continuum’s ACP harness on Codex app-server - not a reimplemented model.
  • Managed Codex sessions stream transcript, tools, and turn state into Code panes via Continuum’s Codex harness.
  • Secondary accounts isolate CODEX_HOME under Continuum’s instance roots; primary env stays golden.
  • Worktree + PR panes wrap the same session; spawn grid can open plain `codex` TUI tiles when you want interactive CLI.
  • Analytics parse Codex session JSONL into the local ledger with LiteLLM rates; no Continuum proxy markup on your plan.
  • Analytics still read Codex session JSONL for the ledger even though live chat is harness-driven.

04 · What Continuum adds around Codex
01 · Single vs multi

Codex alone is a silo. Continuum is a switchboard.

If every session is Codex-only, OpenAI’s surfaces may be enough. The moment you also run Claude Max - or want to compare answers - Continuum becomes the place sessions actually live. Continuum’s SessionFileResolver hardens cwd matching so foreign Codex rollouts (spawn tiles, other terminals) cannot hijack a live session transcript.

02 · Lineage & workbench

Transcripts, plans, PRs - one thread.

Continuum’s Code tab is built as an agent workbench: plan tracker, git diff, PR, artifacts, multi-terminal. Codex is the runtime; Continuum is how you operate it all day across devices. Multi-account CODEX_HOME isolation keeps work and personal auth from clobbering each other under Continuum instance roots.

03 · Accounts

Work Codex and personal Codex without clobbering auth.

Continuum’s multi-account path isolates CODEX_HOME so secondary logins do not stomp the primary. That is a Continuum problem-to-solve, not a Codex CLI feature.

04 · Cost truth

Repo-level dollars, not vibes.

Continuum aggregates Codex (and Claude) history into a local ledger. You see which repo and which provider ate the week - beside live gauges for the windows that matter.

05 · Coexistence
Stack recipe

Same engine. Bigger cockpit.

Stack recipe: Continuum drives real Codex via the ACP harness / app-server path for live Code sessions. Your ChatGPT / Codex usage stays on your OpenAI account. Keep native Codex surfaces for OpenAI-only days; use Continuum when Claude peers, multi-account homes, or mobile approve matter.

06 · Host Codex or stay native-only
Continuum

Choose Continuum when Codex is one peer among many

  • Run real Codex next to Claude and other agents in one sidebar. Continuum Code panes stay first-class: chat, plan, diff, PR, terminal, artifacts.
  • Isolate multiple Codex accounts with separate CODEX_HOME roots.
  • Approve and steer from iPhone while Codex runs on the host.
  • Run Claude and Codex on the same ticket in parallel sessions.
  • See local $ and token rollups by repo for Codex history.
Codex

Stay native when OpenAI alone is the whole stack

  • Only want OpenAI’s native Codex product surface. Continuum will not pretend to win that job with marketing wording alone.
  • Do not need Claude or other labs in the same workbench.
  • Happy without Continuum mobile or multi-account isolation.
  • Prefer OpenAI’s own usage UI over a local multi-lab ledger.
  • Want the smallest stack: Codex alone.

Their bill

Included with the OpenAI / ChatGPT plan that unlocks Codex for you - verify openai.com pricing as of 2026. Continuum does not replace that bill.

How to compare

Total cost of work

As of 2026 - verify on continuumcode.ai/pricing and the vendor site. Continuum does not mark up BYOK or subscription sessions it drives under your login. Live chat uses Continuum’s harness on Codex’s runtime under your auth - not a reimplementation of the model.

08 · Questions

Codex + Continuum.

Deep dives: docs, providers, sessions.

Wrong comparison. Continuum runs Codex. Continuum is better when you need multi-provider, mobile, multi-account, or analytics. Codex alone is better when you only want OpenAI’s native product.

No. Live Codex chat goes through Continuum’s harness on top of Codex’s own runtime - not a second-rate reimplementation of the model.

Yes. Open parallel Code sessions (often separate worktrees), compare diffs, and keep the stronger branch. Continuum’s bet is multi-session fleet ops - not a single-vendor silo.

For Codex subscription rails, you need whatever OpenAI plan unlocks Codex for you. Continuum does not replace that bill.

On your machine (and Continuum’s local-first stores). Continuum’s analytics read session history into a local ledger; keys and transcripts stay under your control by default.

A full HOME override breaks git/ssh/gh/node in worktrees. Surgical CODEX_HOME isolation keeps secondary accounts separate without wrecking the rest of the toolchain.

Live managed Codex sessions stream through Continuum’s ACP / app-server harness into the Code tab. Historical JSONL-only decoders are not the live path - edit harness behavior, not old file parsers.
