Confirmed by OpenAI Tibo: GPT-5.6 Sol Ultra will be in Codex.
Tomorrow is going to be an insane day.
@haider1 Ultra will be in codex.
@thsottiaux @haider1 Stop the slop shit posting bro. We watched you shitpost for the past month.. give us gpt 5.6 today
@thsottiaux @haider1 Couple days ago @jxnlco asked why use the ChatGPT app when codex exists
Pro is a major reason
@thsottiaux @haider1 this is all i wanted to hear :') no more getting codex to consult gpt pro
@thsottiaux @haider1 Already have my debit card ready to upgrade from 5x to 20x the moment 5.6 drops. I cannot wait.
@thsottiaux @soumitrashukla9 @haider1 Sol Ultra or Terra Ultra?
The latter would just be equivalent to 5.5 on xhigh with workflow, no?
@thsottiaux @haider1 Pro is not ultra though is it? Pro is something else? Ultra is just longest thinking time? So many words need to be defined.
@thsottiaux @haider1 can you guys explain what the hell is the difference between ultra pro and just spawning subagents??
@thsottiaux @haider1 Will it be on the $200 a month plan?
@giffmana yeah, exactly. OpenAI could really score a huge win if they released 5.6 on the exact same day Fable 5 is removed from the subscription service.
@gpt_alex @thsottiaux @haider1 @jxnlco and the ChatGPT web version has things the ChatGPT app doesn't have (deep research). and the iOS version has things the web version doesn't have (pro-extended).
@thsottiaux @haider1 tibs, will we finally get 1m context... not sure why 5.5 has 1m in api but not in codex, honestly a deal breaker for me. the compaction loops are ruthless man
@thsottiaux @haider1 Make it 1m context on the sub and plenty will switch
@313Wentzy @thsottiaux @haider1 i like how you dont work for openai and made that up nor is it based on actual evidence or insider leaks but felt the need to reply anyways
@thsottiaux @haider1 What about ChatGPT-5.6 Sol Ultra Spark?
@thsottiaux @haider1 oh that changes things massively
GPT-5.6 really needs to arrive soon.
If it comes too late, a lot of people may simply move over to Anthropic’s Claude.
What are people expecting from GPT-5.6?
A higher ranking across major benchmarks? A real upgrade in capability? Better agents? Lower token usage for the same tasks, with better results?
What I really hope we don’t get is a model that is powerful and genuinely useful, but so expensive that most people can’t afford to use it — or one where a few minutes of work burns through a five-hour usage limit in one go.
Better models are great, but accessibility and usability matter just as much.
@thsottiaux @haider1 750tps + Ultra = GPT-5.6 Sol Ultrafast
@kimmonismus Stop hyping that it will release tomorrow. 99% of your posts are so fake. I wonder how you got so popular
@thsottiaux @haider1 Codex has been pretty incredible
I use it all day and then hit fable api for some of the deeper/outside of the box questions. Then have codex look it over and do the work. Codex never hitting limits and I push it through a lot
