🏙️ No existen dos ciudades inteligentes de la misma manera.

Esa fue la premisa del II Foro de Inteligencias de Ciudad que celebramos en Linares: pensar cómo cada territorio combina sus capacidades económicas, tecnológicas, sociales, culturales y naturales. 🧵👇

I open-sourced ThreeUI, my library of three.js components and landing pages.

160+ are free, and the tool is free too. It includes procedural 3D hero sections, icons, and motion designs. Copy the prompt or source, give it to your agent, then change the theme, lighting, motion or layout.

Live site: https://t.co/rtCfqeZnOP

Repo: https://t.co/B66ahgxHVl

I'm adding a lot more soon. Pro comes with 50+ extra components, MCP, and skills. Early adopters get 50% off right now.

La mejor noticia para un Viernes de desarrollo 🥹👏

[Tibo @thsottiaux]

It's me again. I come bearing great news.

First of all, we have hit 20M active users for Codex some time this week. Second of all, this is cause for celebration and during the day we will credit every Codex and ChatGPT Work user with a BANKED reset that you can use at your own leisure. And we will have some other good news later too!

Now, on usage limits draining faster, while we're not seeing anything abnormal, we do take it incredibly seriously and there is an ongoing investigation. I will share if we do find anything and my below post is really a clarification on a specific pattern that we did see that I wanted to call out.

Go do something amazing today.

I actually use Codex a lot... more than most people asking for resets in the replies. And it is with my heavy usage that I know that Codex limits are just not as good as they used to be.

With GPT 5.5, I had a $100 plan and it'd be impossible for me to meet my daily and weekly limits. I'd have Codex working on 2 projects concurrently, running code reviews, using image gen, and controlling my browser. And I still would have usage leftover.

Now, with GPT 5.6, an entire week's of usage can be burned in a couple hours with GPT 5.6 Sol Ultra on the same $100 plan. This is absolutely absurd.

It was so bad that OpenAI had to investigate this for weeks once they received complaints from countless users. And Tibo confirmed that GPT 5.6 Sol used more tokens than GPT 5.5 at the same reasoning. They've made some improvements to their tool calls that should have resulted in 18% higher usage with Sol. And I'm grateful for the team's effort. But it still feels worse than GPT 5.5 did. And I know I am far from the only one who thinks this.

I still love my ChatGPT subscription.
I love the no weekly limits.
I love its technical excellence at coding.
I love that there's no gatekeeping of models.
And I vastly prefer it to Claude's.

But I won't pretend that limits have not felt worse with the introduction of GPT 5.6, despite OpenAI's claims that it's 50% more efficient in agentic coding.

And those were largely masked by the frequent resets we received every 2-3 days. As OpenAI begins monetizing resets, free resets will be less frequent. Which can effectively reduce overall limits by up to 57%.

Today, the $100 plan feels like the minimum to get any good usage out of Sol. Which GPT 5.4 and GPT 5.5 didn't desperately need. We're gradually treading an upward trajectory of how much money we need to spend to get the equivalent usage across consecutive releases.

I'm really hoping GPT 6 or Astra doesn't represent another spike in overall usage, such that even the $100 plan won't feel sufficient.

[Tibo @thsottiaux]

Here is how to enable a 1M-token context window in Codex for GPT-5.6 Sol.

Even though we have tuned the context limit in Codex to be set optimally when it comes to performance and cost, this is a common ask, so here it is documented.

A larger context window lets Codex retain more code, tool output, and conversation history before summarizing older material. You need a model that supports it. And GPT-5.6 Sol, for example, has a documented 1,050,000-token window.

Open ~/.codex/config.toml and add or update these settings at the top level, before any [section] headers:

```
model = "gpt-5.6-sol"
model_context_window = 1000000
model_auto_compact_token_limit = 900000
```

The first setting selects the model. The second tells Codex to use a one-million-token context budget. The third starts automatic history compaction around 900,000 tokens, leaving some headroom. Restart Codex client and start a new session after saving.

To try the configuration for a single CLI session without changing your defaults:

```
codex -m gpt-5.6-sol \
-c model_context_window=1000000 \
-c model_auto_compact_token_limit=900000
```

Have fun, but also know that we tuned the default carefully!

Today we're releasing Computer History in ChatGPT.

It lets ChatGPT learn from everything you do on your computer, so it can better understand how you work, finish tasks that you're in the middle of, and suggest skills and automations based on how you use your computer.

[Chris @ChrisGPT]

Exciting to hear OpenAI will release an update next week that should make extremely long ChatGPT and Codex conversations dramatically lighter. In one internal test (using an unusually massive 741 turn, 231 MB conversation)

> 94% faster 27.62s to 1.66s average load time
> 87.8% less conversation-renderer memory growth
> 41.2% less whole-app memory growth
> 98.2% fewer requests 894 to 16
> 99.6% fewer transcript items loaded 15,529 to 64

This is great, I can’t tell you how many times opening up an extremely long thread took minutes long.

This week's ChatGPT feature drop - Aug 14:

1/ Quizzes - "Quiz me on [topic]" will now automatically generate quizzes right in Chat. Learn any topic!

2/ Reservation search - "I'm looking for a reservation for two next Saturday for a place with a great outdoor patio". Nice thing is you can just describe what you want.

3/ Google Drive for Paid Users - You can now add Google Drive files to your ChatGPT Library. That makes it easy to ask ChatGPT questions about those files. Just hit the + menu and "Add from Library"

4/ Suggestions for Paid Users - Paid users will see high quality suggestions on the home page of ChatGPT

We're continuing to make answers better, allow you to pull in the right documents, and more easily discover what Chat can do. Step by step, ChatGPT gets more useful! Leave feedback in the comments.

Gracias @thsottiaux. Que detalle!!

[Tibo @thsottiaux]

I previously promised a reset for every 1M in additional active users for Codex, until 10M.

We blew past that and have been silent since 10M. Little surprise for you tomorrow.

A Note to Our Users

Manus will soon resume operating as an independent company.

As part of this transition and to comply with regulatory requirements in specific jurisdictions, some users will need to back-up their data before 7:59 a.m. on August 23, 2026 (SGT) and then begin restoration starting from 8:00 a.m on August 25, 2026 (SGT) to ensure normal usage.

More information can be found in the blog post and we’ve provided detailed guides, including to understand if you’re affected, in our Help Center

For affected users, these are the key details:

We’ll notify you by email and in the Manus app. If you signed up with an Apple ID or Facebook account, please check your in-app notifications.

Back up your data from now until August 23 (SGT) before 7:59 a.m. You can back up more than once, you can create new data after backing up, just run it again.

Starting from 8:00 a.m. on August 25 (SGT), the restoration portal will open. Restore your data and pick up right where you left off.

Affected users will not be charged during the transition, and we will be providing welcome back bonuses.

If your account is not affected, you don’t need to do anything - keep using Manus as usual. You’ll get an in-app notification confirming this.

For those affected, we know this is disruptive and we’re sorry for the inconvenience. Supporting you through it is our top priority. In addition to the full guides in the Help Center, our customer service team is ready to help 24/7 with any questions.

As we look ahead, we couldn’t be more excited by the future. We’re preparing a series of new features that will push the boundaries of what’s possible for general AI agents once again.

Thank you for being with us as we go through this process together. The best is still ahead.
