I bet you didn't know that by default Codex only runs max 3 subagents concurrently. That's not ambitious enough for Astra. OpenAI tested Astra with up to 64 subagents. Copy this into your config.toml: [agents] max_concurrent_threads_per_session = 64 Astra orchestrating 64 Luna subagents in parallel is a sight to behold!

I use subagents for ~80% of my Codex tasks these days. If you're new to subagents, here's a quick primer: - Subagents = separate agents that work on a specific piece of work in a fresh isolated context window. - Your main thread can create subagents and delegate work to them. - Subagents report back when tasks are complete. - Codex subagents are especially useful for read-heavy tasks (e.g research, investigation, and review). - Also useful for testing and building parts of a project in parallel. Subagents are great for working on focused parts of a big task, like planning, implementation, testing, or review. My biggest pro tip for using subagents in Codex: You don’t have to design the entire delegation plan yourself. Just ask Codex to “Use subagents as needed,” and then Codex can then decide where subagents would help it in the task. Here's a demo of using subagents in Codex:

Most people don't know the difference between skills, subagents, and MCPs. Here's the simple breakdown: Skills: Written guides that tell the LLM exactly how to do a task "Analyze spreadsheets this way" or "write emails in this voice" Reusable. Consistent output. Subagents: Extra copies of the LLM, each with its own job - You review code. - You write tests. - You update docs. Work happens in parallel. Stays organized. MCPs: - Universal power plug for external tools - Need to update Linear tickets? Access your database That's MCP. Think: - Skills = how to do something - Subagents = who does what (in parallel) - MCPs = what tools you can reach Play around with all three. That's where it clicks.

this is f**king insane I was burning $100 in a single night running AI agents before this. DeepSeek V4.1 Flash costs ~1/70th of Astra, and someone figured out how to make Astra orchestrate while Flash does almost all the work. [it takes 3 mins to set up — here is how] 1. install `codex-router` 2. connect DeepSeek V4.1 Flash 3. paste the routing prompt voila. Astra thinks. Flash executes. ~$50/month instead of burning hundreds on frontier models. save this and give it to your agent now 👇

Introducing Claude Code Hook - Context Timeline (Saving this to try later) Install with: npx claude-code-templates@latest --hook monitoring/context-timeline Managing the context window and the subagents running in Claude Code is hard to keep track of That's why I built this hook... It starts the moment you open a session and shows a timeline with the main agent's context window and how subagents start working in their own separate context Every subagent you have running will show up in real time This way you can manage the context and the subagents you run, and see everything in a much simpler way than in the console

Sam Altman (OpenAI CEO): “With GPT‑6 Astra, prompts are basically optional.” In a 10‑minute rundown, he shows how a single person can now crank out what a full team used to grind through for a month. His advice is simple: keep escalating the difficulty codebases, research, end‑to‑end simulations. Astra will take on more than you’d think to even attempt. Watch the clip, then dive into the guide below for the simplest way to spin up your own Astra‑powered AI agent squad for free.

The underrated part of GPT-6 Astra for editing is iteration. I can describe a very specific cinematic grade → Astra generates a .cube LUT → import it into CapCut PC → see it on the actual footage. Too warm? Too contrasty? Not enough separation? Adjust it in CapCut PC, or go back to Astra and generate another version. That creates a much faster loop between creative direction and execution. Astra makes the custom assets. CapCut PC gives me the environment to judge and refine them. #GPT6Astra #CapCutPC #AIVideo #Seedance25

This is so cool. In the next Codex update, multi agents will get a massive flexibility upgrade. "Hey Codex, when you implement this plan, I want you to delegate all the lower complexity tasks to GPT 5.3 Spark subagents" Instead of needing to create 100 different custom agent roles for different situations, you can just prompt your agent to spawn whatever model or reasoning level you want. With only natural language. No config files. No pre-defined roles. Just tell the orchestrator what to use and it listens.

GPT-6 Astra is now available to all Pro, Enterprise and Business Premium users in ChatGPT Work and Codex. It’s also live in the API. It's a phenomenal model and I love every second working with it! Astra follows instructions more closely, so revisit your prompts and skills: > Make “can you…” mean “do it”: finish authorised work and prepare a reviewable result before seeking approval. > Audit AGENTS.md and skills. Ask it to identify the exact file and rule blocking progress. Prioritise your request over skill guidelines. > Specify short paragraphs, plain language and phrases to avoid. > Ask for subagents on independent work when it improves speed or quality. > Run relevant checks. Repeat or expand only for changes, failures or unresolved concerns. To push it to it's limits, I gave it a prompt to build a real-scale video fly through of nürburguring track in blender and it did not disappoint! Enjoy! ✨

Codex built me a full Memory Manager overnight using my new "Teams" strategy. Flawless first test. One prompt spun up 70 domain-expert subagents, organized into specialized teams, all working in parallel to one-shot the entire app while I slept. I've built over 200 custom subagent roles for this. Playbook dropping soon. This is a massive unlock for parallelization. I'll be improving this and testing it on much larger projects.

You know I had to do it!! gpt-6-astra (High), one prompt, Terreiro do Paço in Lisbon (Blender, not Three.js!) This one hits home personally 5 years ago, in college, I had a whole course in Computer Graphics. For the final project, every group had to recreate Praça do Comércio / Terreiro do Paço in Blender (our project delivery is in the comments). I wanted to see how Astra would perform. For one-shot, it's pretty damn good. Astra is a beast in Spatial 3d, and Blender is not like Three.js! It's significantly more complex, with a broader range of modeling, materials, lighting, etc. Generational leap (and I will run a few more prompts here)

9 out of 10 multi-agent projects never leave demo mode Not because the model is bad. Because the structure is missing. Most people who try to build [ a team of AI agents ] end up with one agent talking to itself in five tabs.

holy sh*t this is f**king dangerous A Chinese guy figured out how to run fable 5.1 for FREE on gpt 5.6 luna subagents on every task You’ll never hit an agent usage limit how you set it up (3 mins) 1. install the 'fable-orchestrator' repo 2. type /fable orchestrator [task] 3. done, that's it Give this to your agent immediately. It’s the best thing you can do this week.

OpenAI just released GPT-6 Astra, and OpenAI President Greg Brockman is calling it a generational leap, saying he personally believes it could mark the arrival of AGI. Astra launched on Thursday, September 3rd, 2026, following July's GPT-5.6 solo release. Brockman told reporters, "For me personally, I do think we're there. Directionally, I believe this. I think we're on a path to AGI. The timing I think is kind of uncertain, but we are definitely on a path to AGI." OpenAI executives say Astra moves past the chatbot era, capable of handling end to end work on its own across browsers, spreadsheets, codebases, and enterprise apps without a human in the loop. The model was trained on over 100,000 GPUs at the Stargate site in Texas. Access starts through OpenAI's gated Daybreak Access cybersecurity program for enterprise customers, then rolls out to ChatGPT Plus, Pro, Business, and Enterprise, plus the API and Amazon Web Services over the coming days. Ahead of launch, two models appeared in Codex, GPT-6 Astra and GPT-6 Astra Aeon, with the latter believed to be a higher effort, long horizon variant built for autonomous multi agent work.
