Industry speculation points to an upcoming Thursday launch for OpenAI's rumored GPT-5.6 Sol model
Story Overview
A cluster of social posts is buzzing about OpenAI potentially rolling out its GPT-5.6 Sol Ultra variant around July 9, yet the only firm event on record remains the limited preview of the broader GPT-5.6 family that began June 26 for roughly twenty trusted partners.
Benchmarks hint at agentic gains
Sol already posts strong scores on TerminalBench 2.1 when running in Ultra mode with subagents, but no one outside the preview circle has tested whether those numbers translate to everyday coding or planning tasks.
Rollout details stay murky
OpenAI has floated general availability in the coming weeks and integration with Cerebras hardware, yet exact dates, usage caps, and which ChatGPT tiers will see Sol Ultra remain unspecified.
Positive users are excited about the GPT-5.6 launch promising faster releases and new agent workflows, while negative users remain skeptical of repeated unfulfilled date predictions.

Sounds like Gemini 3.5 Pro arrives around July 17th with a brand-new pretrain. Unless, of course, the government blocks it. People are pretty down on Google right now, but I think they'll be surprised. July is a month for Kaiju fights.
🚨 SCOOP:
As previously reported, OpenAI plan to launch GPT-5.6 once back in office next week, with a target window of July 7-9, but want it out as early as possible within that window (so July 7th is the most likely date). This is also perfect timing to catch customers coming from Claude who have just lost their access to Fable 5 in plans, and I'm told the 5.6 plan limits will be significantly more generous. More aggressive safeguards are already being rolled out in preparation for the launch too, although they probably won't be as aggressive as Fable's.
DeepMind have also tentatively set a new launch date for Gemini 3.5 Pro of July 17th. Apparently, this extra time has been spent on a new pretrain (they were planning to keep using the ancient 2.5 Pro base, lol), but it remains to be seen whether it's any good. I'm not hopeful. In other news, work is well underway on a new Nano Banana Pro model based on the new 3.5 Pro base, which I expect to be better received and compete well with GPT-Image 1.
It would be the perfect time for OpenAI to release GPT-5.6 on July 7th, the same day *Fable 5* was removed from the subscription tier.
Within a single day, there would be a massive influx of new Pro subscribers using Codex.
its coming. already restarted codex, but nothing for me yet. looks like i have to wait until tuesday
Oh hello, GPT-5.6 Sol 👀
Did I just get early access or what?
My Codex is showing a new model-style in popup with Sol, Terra, Luna, and a new speed selector.
Something is cooking.

GPT 5.6 will mog Feeble
GPT 5.6 launches next week.
The SAME WEEK Anthropic pulls Fable 5 from subscriptions.
And for the first time, OpenAI actually has a shot:
- GPT 5.6 Sol Ultra already beats Fable 5 on TerminalBench: 91.9% vs 84.3% - Half the price - Less guardrails killing normal coding tasks - No weekly limit that serious builders burn in 24 hours
Fable 5 is the best model on earth, but the guardrails and rate limits are nerfing it.
GPT 5.6 is going to have less guardrails and the rate limits will be WAY better.
Next week decides everything.
@kimmonismus I have a theory, the US gov 'shut down' 5.6's release so openai can stall to make better adjustments on the benchmark, so that on paper they released it last week but because 'oh no its not us it's the government so we have to take a pause here'.
@AndrewCurran_ Yes I have hopes on Gemini 3.5 Pro
@AndrewCurran_ My BD! 📅

@AndrewCurran_ Is it bullish or bearish for Google if the government blocks it
@kimmonismus Will that be the same day that Fable is re-enabled for subs? 😄
@PaulGugAI huh? wdym. it already is re-enabled for subscrition right now
@beffjezos Altman will never let this chance pass by, really bad move by Anthropic
@MrMSpencer They may already have been/are blocked, we have no way of knowing. OpenAI has been trying to get GPT-5.6 approved for release since before Fable was banned for example, we just didn't know anything about it until it was reported during the Fable negotiations.
@AndrewCurran_ should google be annoyed if it's not blocked to start off with? If so it'll imply they'll go from ChatGPT 5.1-5.2 level capability to around Chat 5.5 (similar to open GLM 5.2 but way off frontier?)
@kimmonismus I literally dreamed about it
@philltopia Bullish.
@kimmonismus Timing a drop right when your rival pulls a perk is the oldest playbook in tech.
@AndrewCurran_ Forgive my ignorance, but I've heard about XAi running new pre-training each month. Could someone explain why they would do that?
Is it about cleaning up the data for the pre-training model or something else?
@kimmonismus fake it till you make it, huh?
@ChiaraCervetta @kimmonismus Hope it's at least good at world knowledge and creative ideation.
@altryne Happy birthday, let's hope Logan delivers a good present.
