Any quick impressions of o3 vs o1? We've got one inference in our product that only o1 has seemed to handle well, wondering if o3 can replace it.

They are replacing o1 with o3 in the UI, at least for me, so they must be pretty confident it is a strict improvement.

Interesting that using tools to zoom around the image is useful for the model. I was kind of assuming that these models were beyond such things and could attend to all aspects image simultaneously anyway, but perhaps their input is still limited in the resolution? Very cool, in any case, spooky progress as always.

I have a very basic / stupid "Turing test" which is just to write a base 62 converter in C#. I would think this exact thing would be in github somewhere (thus in the weights) but has always failed for me in the past (non-scientific / didn't try every single model). Using o4-mini-high, it actually did produce a working implementation after a bit of prompting. So yeah, today, this test passed which is cool.

Unless I'm misunderstanding what you are asking the model to do, Gemini 2.5 pro just passed this easily. https://g.co/gemini/share/e2876d310914

As I mentioned, this is not a scientific test but rather just something that I have tried from time to time and has always (shockingly in my opinion) failed but today worked. It takes a minute of two of prompting, is boring to verify and I don't remember exactly which models I have used. It is purely a personal anecdote, nothing more.

However, looking at the code that Gemini wrote in the link, it does the same thing that other LLMs often do, which is to assume that we are encoding individual long values. I assume there must be a github repo or stackoverflow question in the weights somewhere that is pushing it in this direction but it is a little odd. Naturally, this isn't the kind encoder that someone would normally want. Typically it should encode a byte array and return a string (or maybe encode / decode UTF8 strings directly). Having the interface use a long is very weird and not very useful.

In any case, I suspect with a bit more prompting you might be able to get gemini to do the right thing.

So at this point OpenAI has 6 reasoning models, 4 flagship chat models, and 7 cost optimized models. So that's 17 models in total and that's not even counting their older models and more specialized ones. Compare this with Anthropic that has 7 models in total and 2 main ones that they promote. This is just getting to be a bit much, seems like they are trying to cover for the fact that they haven't actually done much.…

"haven't actually done much" being popularizing the chat llm and absolutely dwarfing the competition in paid usage

ChatGPT was released two and a half years ago though. Pretty sure that at some point Sam Altman had promised us AGI by now.

The person you're responding to is correct that OpenAI feels a lot more stagnant than other players (like Google, which was nowhere to be seen even one year and a half ago and now has the leading model on pretty much every metric, but also DeepSeek, who built a competitive model in a year that runs for much cheaper).

As someone who doesn't use anything OpenAI (for all the reasons), I have to agree with the GP. It's all baffling. Why is there an o3-mini and an o4-mini? Why on earth are there so many models? Once you get to this point you're putting the paradox of choice on the user - I used to use a particular brand toothpaste for years until it got to the point where I'd be in the supermarket looking at a wall of toothpaste all b…

> Why is there an o3-mini and an o4-mini? Why on earth are there so many models? Because if they removed access to o3-mini — which I have tested, costed, and built around — I would be very angry. I will probably switch to o4-mini when the time is right.

They just did that, at least for chat

As a consumer, it is so exhausting keeping up with what model I should or can be using for the task I want to accomplish.

Gemini 2.5 Pro for every single task was the meta until this release. Will have to reassess now.

Huh. I use Gemini 2.0 Flash for many things because it's several times faster than 2.5 Pro.

> All these models feel like they took the exact same base model, tweaked a few things and released it as an entirely new model rather than updating the existing ones.

That's not a problem in and of itself. It's only a problem if the models aren't good enough.

Judging by ChatGPT's adoption, people seem to think they're doing just fine.

Im old enough to remember the mystery and hype before o*/o1/strawberry that was supposed to be essentially AGI. We had serious news outlets write about senior people at OpenAI quitting because o1 was SkyNet Now we're up to o4, AGI is still not even in near site (depending on your definition, I know). And OpenAI is up to about 5000 employees. I'd think even before AGI a new model would be able to cover for at least 45…

> Im old enough to remember the mystery and hype before o*/o1/strawberry So at least two years old?

Honestly, sometimes I wonder if most people these days kinda aren't at least that age, you know? Or less inhibited about acting it than I believe I recall people being last decade. Even compared to just a few years back, people seem more often to struggle to carry a thought, and resort much more quickly to emotional belligerence.

Oh, not that I haven't been as knocked about in the interim, of course. I'm not really claiming I'm better, and these are frightening times; I hope I'm neither projecting nor judging too harshly. But even trying to discount for the possibility, there still seems something new left to explain.
