OpenAI's Vaibhav Srivastav says Codex can spawn sub-agents and run persistent workflows in remote environments

Story Overview

OpenAI engineer Vaibhav Srivastav highlighted fresh Codex features that let the system spawn sub-agents when prompted, build loops and new threads for automations, and hand tasks to remote environments so execution keeps going after a laptop shuts down.

Yes and it can do even MORE: Codex can spin up it’s own sub agents (when prompted), create automations, heartbeats (loops) and start new threads

bonus: if you’ve got remote connection setup you can offload a task to remote and have codex continue working on it even when your laptop is turned off

AYO? Codex can now message agents?

Is this something new in the new Codex update.. oh yeah they are 100% preparing for GPT 5.6

I've asked Codex to do this before and it told me it couldn't so... this seems new?

Developer Impact

What changes for daily agent runs

Sub-agents now handle independent model and tool work on demand while remote offloading uses QR pairing and plugins like Digital Ocean for VM setups, all generally available since March or late June 2026 depending on the piece.

Open Question

Still unclear on costs and scale

Each sub-agent increases token use versus single runs, yet exact pricing tiers, user numbers, and enterprise controls remain unspecified in current sources.

Sentiment

Positive users praise OpenAI Codex sub-agent spawning and remote offloading as killer multi-agent unlocks, while negative users cite unreliable iOS threading, lost traces, and debugging or SSH automation limits.

for clarity: this has been the case for awhile, not something to do with 5.6

@maxjendrall everything except the last bit has been possible for over a month

offload to remote connections came out couple weeks ago IIRC

to be honest I never seen it do it and sometimes when i'd ask it to do it it wouldn't..

to be honest i'm still really wanting a slightly higher context like 400k or 512k or even just 1 million even open weight models have 1 million now and GPT 5.5 and most likely GPT 5.6 lacks behind... which is upsetting

Also it still sucks that Codex doesn't have a PROPER CI Monitor like Claude Desktop has

@reach_vb at some point your codex has an org chart and you're the only IC left

@reach_vb I do find it hard to get the agents to use other agents. I few times it stops them, because ironically it finds them too slow. The workflow in claude is the only thing that codex is missing atm

@reach_vb Maybe we could get 5.6 today, just to be sure? 🙂

@reach_vb The fact you can’t set up heartbeats or automations on remote SSH servers is annoying.

Codex seems to block you doing so.

@reach_vb Is there away to utilize the ChatGPT app on phone to connect to codex on a VPS?

JJ@JJLiebig

@reach_vb Is this already multi_agent_v2?

I thought this wasn't activated yet, pretty much the largest unlock I'm looking forward to together with 5.6

@reach_vb But you caaaaaaaaaannnnnn

Mario Vellandi@TriforceKid7

@reach_vb So in theory, Codex could send structured messages like we would in actor languages, which the subagents could handle with available tool calls?

@reach_vb Codex got some of the best features, I’ve got to try it out.
