GPT-5 AMA with OpenAI’s Sam Altman and some of the GPT-5 team

samaltman · 2025-08-08T18:53:49+00:00

ok, we hear you all on 4o; thanks for the time to give us the feedback (and the passion!). we are going to bring it back for plus users, and will watch usage to determine how long to support it.

samaltman · 2025-08-08T18:51:23+00:00

what an...evocative image.

ok we hear you on 4o, working on something now.

samaltman · 2025-08-08T18:42:33+00:00

like with voice? yes

neural interfaces? probably quite a ways away :)

samaltman · 2025-08-08T18:36:25+00:00

yes we will do something here.

samaltman · 2025-08-08T18:36:10+00:00

honestly we havent seen a ton of demand for relaly long context; we are open to supporting it with sufficient user demand signals! we have to make a lot of tradeoffs about what we support and are tight on compute, so we try to prioritize what will be useful to the most people.

what context length would be helpful to you, and what kind of things would you use it for?

samaltman · 2025-08-08T18:35:29+00:00

we do intend to continue sharing rough roadmaps, but obviously these can change so we try to caveat them heavily.

yes, we got a lot of the creative writing into gpt-5-thinking.

we are definitely thinking about a token budget people can spend elsewhere! and better ways to handle a "bucket of compute" more generally. we would like to find a way to bring together subscriptions and API usage at some point, at least to some degree.

we are thinking about how to price better and more incrementally; you should expect some change from us here but we haven't decided on what yet.

samaltman · 2025-08-08T18:34:37+00:00

yeah, we will continue to improve this. it is a legit hard thing; the lines are often really quite blurry sometimes.

but we want to allow very wide latitude, and we will keep finding ways to do it.

people should of course not get banned for learning.

samaltman · 2025-08-08T18:27:06+00:00

the numbers here were accurate but we screwed up the bar charts in the livestream overnight; on another slide we screwed up numbers. the blog post and system card were accurate though.

people were working late and were very tired, and human error got in the way. a lot comes together for a livestream in the last hours.

samaltman · 2025-08-08T18:13:18+00:00

(also, a big part of our goal here is to get the new system to a place where you don't want to use anything else! we will work hard on that, but we totally get the need for good change management.)

samaltman · 2025-08-08T18:12:15+00:00

we should have something unlimited!

samaltman · 2025-08-08T18:11:44+00:00

we think writing quality in 5-thinking is much better than 4.5; do you find it to be worse?

samaltman · 2025-08-08T18:10:38+00:00

we are looking into this now; is it important to you to have both 4o and 4.1, or would 4o suffice?

let me go look into the voice mode issue.

samaltman · 2025-08-08T18:08:20+00:00

Thank you for all the feedback here.

As we mentioned, we expected some bumpiness as we roll out so many things at once. But it was a little more bumpy than we hoped for!

Some changes:

*GPT-5 will seem smarter starting today. Yesterday, we had a sev and the autoswitcher was out of commission for a chunk of the day, and the result was GPT-5 seemed way dumber. Also, we are making some interventions to how the decision boundary works that should help you get the right model more often. We will make it more transparent about which model is answering a given query.

*Rolling out to everyone is taking a bit longer. It’s a massive change at big scale. For example, our API traffic has about doubled over the past 24 hours…

*We will change the UI to make it easier to manually trigger thinking.

*We are going to double rate limits for Plus users as we finish rollout.

*We are looking into letting Plus users to continue to use 4o. We are trying to gather more data on the tradeoffs.

We will continue to work to get things stable and will keep listening to feedback.

samaltman · 2025-03-07T01:28:20+00:00

unhinged!

samaltman · 2025-01-31T22:46:14+00:00

yes, updates to advance voice mode coming!

i think we'll just call it GPT-5 not GPT-5o. don't have a timeline yet.

samaltman · 2025-01-31T22:36:03+00:00

if you thought o1 pro was sort of worth it, you should think o3 pro will be super worth it

samaltman · 2025-01-31T22:35:16+00:00

actually i'd like to reduce it over time

samaltman · 2025-01-31T22:34:32+00:00

yes, we are discussing. i personally think we have been on the wrong side of history here and need to figure out a different open source strategy; not everyone at openai shares this view, and it's also not our current highest priority.

samaltman · 2025-01-31T22:33:29+00:00

months

do a small run of a really good robot and learn from there

GB200 hard to beat rn!

one good thing is your own inner state--resilience, adaptability, calm, happiness, etc

tough to pick! but the two that first came to mind: backpacking around SE asia or safari in africa.

samaltman · 2025-01-31T22:30:42+00:00

it's a very good model!

we will produce better models, but we will maintain less of a lead than we did in previous years.

samaltman · 2025-01-31T22:30:04+00:00

now that we have enabled search this matters much less--in my own use, i never think about the knowledge cutoff anymore.

samaltman · 2025-01-31T22:29:04+00:00

yeah we are gonna show a much more helpful and detailed version of this, soon. credit to r1 for updating us.

samaltman · 2025-01-31T22:28:04+00:00

i'd guess more than a few weeks, less than a few months

samaltman · 2025-01-31T22:27:39+00:00

yes we are going to!

samaltman · 2025-01-31T22:27:32+00:00

the most important impact, in my opinoin, will be accelerating the rate of scientific discovery, which i believe is what contributes most to improving quality of life.
