Other than the worst naming I have ever seen (Sol / Terra / Luna), the pricing is still expensive: > GPT‑5.6 is priced per 1M tokens across three model sizes: > Sol is $5 input / $30 output; > Terra is $2.50 input / $15 output > Luna is $1 input / $6 output. The OpenAI casino has never been more ready to take your money on gambling even more tokens.

"Next generation model" If it was the next generation, why isn't it a major version change..?
ChrisLTD
If it's a new generation why isn't it GPT-6?

Sol? Looks like openai is jealous of anthropics good model naming ability and wants to emulate it.

I'm going to pre-register my prediction that GPT-5.6 Sol is significantly behind Claude Fable 5, as evaluated by general consensus once time has passed for people to get familiar with both.

When will GPT-5.6 Protomolecule drop? Me and the boys on Eros can't wait to get our hands on it!

I'm really getting sick of reading about safeguards and what I'm not allowed to do on every model release.

all the emphasis on cyber security. feels like a reaction to anthropic, not a real next generation.

I'll buy that its next generation if the svg bicycle pelican is carrying a baby

Here is a trend I'm noticing: - GPT-5 mini costs $0.25/$2 and will be discontinued in December. - GPT-5.4 mini costs $0.75/$4.5 and is supposed to be the replacement. - GPT-5.4 nano costs $0.2/$1.25 and, while it ranks better in benchmarks than GPT-5 mini, it's not even close when you test it in real scenarios. So you're left being forced to go to GPT 5.4 mini if you use 5 mini today. The same thing is happening here as their “Luna“ model will cost $1/$6. Can't we just stay with the models we actually want? I don't need GPT 5.4 mini. GPT-5 does the job. Maybe it’s the realization that it was never that cheap in the first place and they're forcing us to upgrade in a slow and painful way.

Not really news until it's widely available. Anyone know the latest around Fable being re-released after gov smackdown?

We need more coding benchmark score. Not sure that winning terminalbench 2.1 alone is a clear win over Fable/Mythos yet.

I think GPT writes code the best. How well will it write in version 5.6? It gives me chills. Recently, I went head-to-head with GPT on nearly 2,000 lines of code, and GPT's solution was superior and faster. I even referenced multiple codebases on GitHub while trying, but they were incomparable to GPT. So using GPT brings both fear and excitement. The fear comes from realizing that this level of code is now the average for most people. The excitement comes from knowing that I can now study and learn at this level too. I'm really looking forward to seeing how much more advanced the code will be with the upgrade to 5.6.

I didn't know that I was color blind, but thanks to those charts, I think I need to see a doctor... I mean, you can read them even without the colors, but who on earth thought that those are a good set of colors? Oh, I forgot it was probably someone on 'Sol'.

Flagged activity can also trigger account-level review across relevant conversations and risk signals, consistent with our terms and policies around content retention and review. Looking beyond a single conversation helps our systems distinguish persistent malicious behavior from legitimate dual-use security work, where similar technical concepts may appear in very different contexts. Fascinating! Every conversation you have with these "more capable" models will be monitored and joined up and then your entire account might one day be tagged as Distiller or Cyber Threat Actor or whatnot. When combined with identity verification (which isn't discussed in this press release), expect people to be falsely flagged and banned from ever using OpenAI models again. Wish I could find the thread from last week where discussions of exactly this kind of thing were dismissed as daft and outlandish.

> Additionally, we’re introducing a new `ultra` mode that goes beyond the capabilities of a single agent by leveraging subagents to accelerate complex work. I'm curious about how does this work? Do the subagents also get to use the same tools? Will the client be flooded with tool calls? Why extra pricing for a new "model" when the same thing can happen in the client with more controls? And if it's an army of subagents, why do they compare it to Fable and Mythos? Those models with similar harness would probably bench better I'm guessing

> As part of our ongoing engagement with the U.S. government, we previewed our plans and the models’ capabilities ahead of today’s launch. At their request, we are starting with a limited preview for a small group of trusted partners whose participation has been shared with the government, before releasing more broadly. The clowns in the US administration can barely remain coherent from one sentence to the next. Having them be the gatekeepers of technological progress in 2026 is fucking lame.
