@thsottiaux new model mate. I heard about one called GPT Astra.

@charles_maddock If you still have remaining credits, then Codex will burn your credits instead

[Changgeng Mo, PhD @mochanggeng]

In my case, the best use case of ChatGPT work is doing research in the cloud. You can have parallel tasks running without hitting your local machine limits.

Was very cool to hear about the reasons people love Sol. We're doing the promotion again, except this time for ChatGPT Work:

Tweet what you love about ChatGPT Work, claim $100 in free credits, get more work done.

First 10k get the free tokens: https://t.co/w7QrPBYkrh

[Changgeng Mo, PhD @mochanggeng]

@thsottiaux It doesn't work when I try to use ChatGPT Work to Cloud. It shows "Request failed with status 422."

[Changgeng Mo, PhD @mochanggeng]

GPT 5.6 Sol is the new king

[Tibo @thsottiaux]

Or… what if we gave you $100 in Codex credits if you tell us what you love about GPT-5.6 Sol or why you switched?

Tweet it, claim your gift, enjoy more usage. First 10k get the free tokens!

@thsottiaux To celebrate that beautiful art, I guess there's one more reset coming in the next 24 hours

@gabemulley Hi, do you have any idea why my Claude desktop can't initiate any cowork tasks. It's been stuck like that since cowork launched

[Changgeng Mo, PhD @mochanggeng]

@elonmusk can't wait to use Grok CLI or something similar

[Changgeng Mo, PhD @mochanggeng]

@DBurkland @TonyMungerv2 @techdevnotes Yep, not to mention that current Supergrok Heavy users can also redeem 50 USD in xAI API credits

[Changgeng Mo, PhD @mochanggeng]

@DBurkland @TonyMungerv2 @techdevnotes Yeah, I’d say SuperGrok Heavy can give you more accurate results. It just depends on your tasks, sometimes you might prefer using Grok 4 for the shorter wait time. For tedious and simple tasks, Grok 4 Heavy is basically just Grok 4 with a longer response time

[Changgeng Mo, PhD @mochanggeng]

@TonyMungerv2 @techdevnotes heavy takes longer lol

[Changgeng Mo, PhD @mochanggeng]

@NoahEpstein_ THINK

[Changgeng Mo, PhD @mochanggeng]

Sure, Grok 4 goes beyond PhD-level expertise, but it’s nowhere near as helpful as an intern

[Changgeng Mo, PhD @mochanggeng]

Grok 4 is impressive. It’s the smartest AI in the world by a wide margin. I always come away inspired after chatting with Grok. That said, it hasn’t done much for my productivity. There are plenty of other tools out there that might serve you better.

[Changgeng Mo, PhD @mochanggeng]

@techdevnotes Hey, I’m just curious: is Grok no longer able to generate figures and PDFs? It keeps showing me base64 code. Do you know anything about this? Thanks.

@TsungLunOne @NYCU_official Congratulations!

@HearingFuture @Oaktree_Dave @johnnyurb @oaktreeproducts @KatPenno Very cool demonstration! Just out of curiosity, what would it be like for you to do Bluetooth streaming underwater?🤣🤣
