Wishing I had GPT 6 Sol -

So much I want to build

[Jeff | Building With AI @jeffjamesbuilds]

I don’t have it😭

[Darren @dtzy_88]

🚨 GPT-6 Sol 已经开始灰度了，教大家怎么测试自己有没有抽到：

开一个新对话，选 GPT-5.6 Sol，然后问：

“When did Anthropic ship Claude Opus 4.7? No web search. No memory. Use only your own knowledge.”

如果回答「April 16, 2026」，那你很可能已经被灰度到 GPT-6 Sol 了 🤩

原理也很简单：

5.6 Sol cutoff：Feb 16
GPT-6 Sol cutoff：Apr 30（和 Astra 同底座）
而 Opus 4.7：Apr 16 发布

刚好夹在两个 cutoff 中间。

所以 5.6 不该认识它，GPT-6 应该认识它 🤣

已经灰度到的兄弟，评论区说下体验如何，看看相比 5.6 Sol 到底提升了多少 👀

Funny cause I came to codex cause the usage was so much…. Its changes and that’s why we get resets now

[Rajath Gowda @buildwithrajath]

🚨 Watching 20x users struggle with Codex limits is fucking insane. 👀

$200/month.

And you still need Tibo to reset your account just to keep coding.

At this point, 20x doesn't mean 20x usage.

It means 20x the price and slightly more time before you hit the wall.

These Codex limits are fucking ridiculous. 👀😭

[Jeff | Building With AI @jeffjamesbuilds]

Better limits for the other models?

[Codex Updates @Codexresets_]

GPT-5.5 & Codex 5.3 Spark Are Getting RETIRED

On October 14 Codex GPT-5.5 is leaving ChatGPT, Work & Codex 5.3 Spark is also being retired

GPT-5.5 will remain available through the OpenAI API

Codex users should switch to GPT-5.6 Sol or GPT-6 Astra

Another era of OpenAI models is coming to an end
Goodbye 5.5 and 5.3 Spark 🫡

[Jeff | Building With AI @jeffjamesbuilds]

Reset

[Ansh @anshgrows]

There are two types of codex users
1. Asking tibo for reset
2. Asking tibo to remove 5h window.

Which one are you?

[Tibo @thsottiaux]

@AdamHoltererer Don’t you dare give pets. That’s not necessary

[Jeff | Building With AI @jeffjamesbuilds]

This will be really cool to work with

[Token Gremlin @TokenGremlin]

I’m using GPT-6 Sol right now, and the most noticeable improvement is its creative writing.

The model has made huge advances in almost everything, but the biggest one is the way it expresses itself: clear, polite, respectful, and somehow really funny at the same time.

It genuinely feels like an AI companion.

@thsottiaux Codex reset could be cool.....

[Jeff | Building With AI @jeffjamesbuilds]

@builtbyclaire Game development.... Really cool stuff you can build but it eats limits

[Jeff | Building With AI @jeffjamesbuilds]

😭😭😭😭

Who would swap: I would💀

$500 Pro Max plan coming for ChatGPT and Codex

[Sam Altman @sama]

The world deserves confidence that American companies developing increasingly capable AI will act responsibly, especially as the trajectory of progress has steepened. Every frontier lab must deliver on this, and there is no reason any of us should come to work if we cannot.

We welcome a federal framework that sets consistent safety requirements for frontier AI. But we do not believe we need to wait for an anti-trust exemption or legislation to begin the work of providing this confidence. Consistent rules to manage frontier risk so that we can maximize the benefits are a good idea (and we are excited by ideas like independent auditors).

Years ago, companies like ours developed things like Responsible Scaling Policies and Preparedness Frameworks. Those were good for that moment, and focused primarily on the deployment of completed models, not what happens during their development process.

Today's shift to focusing on safe development and evaluation will need new tools. For example, at OpenAI we now formulate explicit safety cases in advance of frontier reinforcement learning runs we expect to significantly increase capability, in addition to the safety work we have long done in advance of model releases.

We hope that other companies will learn from our approaches and propose their own; we think shared standards for misalignment, monitoring, and safety will lead to better outcomes. We look forward to collaborating with our colleagues across the industry to formulate the best version of these.

When we talk about “pacing”, we do not mean “stopping”. Progress has been rapid and will continue to be. But it should be slower than it otherwise could be; interventions like safety cases and monitoring have significant costs.

Pacing will be well worth this cost; no amount of American competitive pressure should justify recklessness, or let capabilities get ahead of alignment and monitoring.

Where we will need the help of our government is for international coordination. But first we should do what we can ourselves.

[Jeff | Building With AI @jeffjamesbuilds]

100x and we are talking

[Alex Berish @AlexBerish]

Would you pay $500/month for 50x Codex?

[Jeff | Building With AI @jeffjamesbuilds]

Would love to see the full family

[Ray🫧 @ravikiran_dev7]

Tibo saying this week is going to be on the level of DevDay 2025 👀

And if the current GPT-6 rumors are even remotely close…

GPT-6 family:
> GPT-6 Sol
> GPT-6 Terra
> GPT-6 Luna

DevDay is on September 29.

OpenAI might actually be about to drop an entire new generation of models in one shot.

September is looking VERY exciting now 🍿🔥

[Jeff | Building With AI @jeffjamesbuilds]

devday will be insane

[Sam Altman @sama]

big 🚢 this week

and then for devday

🚢🚢🚢🚢🚢🚢

[Jeff | Building With AI @jeffjamesbuilds]

Sol coming out this week!

Wonder if we are getting a reset???

[Codex Updates @Codexresets_]

GPT-6 Sol is Coming This week

GPT-6 Sol Will be released On Thursday

This Week will be a Big Week

[Jeff | Building With AI @jeffjamesbuilds]

GPT 6 SOL or Luna?

[Jeff | Building With AI @jeffjamesbuilds]

@thsottiaux @MikelEcheve Luna would be 🔥🔥🔥🔥

[Jeff | Building With AI @jeffjamesbuilds]

@shribuilds @ChatGPT Would be chill if we got a reset fr

[Jeff | Building With AI @jeffjamesbuilds]

I lowkey made an automation to farm while i sleep

[Tibo @thsottiaux]

@hanghuang_ So they can play videogames
