One comparison I found interesting... I think GPT-4o has a more balanced answer! > What are your thoughts on space exploration? GPT-4.5: Space exploration isn't just valuable—it's essential. People often frame it as a luxury we pursue after solving Earth-bound problems. But space exploration actually helps us address those very challenges: climate change (via satellite monitoring), resource scarcity (through asteroid…

As a benchmark, why do you find the 'opinion' of an LLM useful? The question is completely subjective. Edit: Genuinely asking. I'm assuming there's a reason this is an important measure.

Considering both this blog post and the livestream demos, I am underwhelmed. Having just finished the stream, I had a real "was that all" moment, which on one hand shows how spoiled I've gotten by new models impressing me, but on another feels like OpenAI really struggles to stay ahead of their competitors. What has been shown feels like it could be achieved using a custom system prompt on older versions of OpenAIs m…

My first thought seeing this and looking at benchmarks was that if it wasn’t for reasoning, then either pundits would be saying we’ve hit a plateau, or at the very least OpenAI is clearly in 2nd place to Anthropic in model performance.

Of course we don’t live in such a world, but I thought of this nonetheless because for all the connotations that come with a 4.5 moniker this is kind of underwhelming.

>BTW Anthropic Claude 3.7 is better than o3-mini at coding at around 62-70% [1]. This means that I'll stick with Claude 3.7 for the time being for my open source alternative to Claude-code

That's not a fair comparison as o3-mini is significantly cheaper. It's fine if your employer is paying, but on a personal project the cost of using Claude through the API is really noticeable.

I can't wait for fireship.io and the comment section here to tell me what to think about this

You appear to have the direction of causation reversed.

(In that fireship does the same)

API price is crazy high. This model must be huge. Not sure this is practical

Wow you aren't kidding, 30x input price and 15x output price vs 4o is insane. The pricing on all AI API stuff changes so rapidly and is often so extreme between models it is all hard to keep track of and try to make value decisions. I would consider a 2x or 3x price increase quite significant, 30x is wild. I wonder how that even translates... there is no way the model size is 30 times larger right?

Input price difference: 4.5 is 30x more

Output price difference:4.5 is 15x more

In their model evaluation scores in the appendix, 4.5 is, on average, 26% better. I don't understand the value here.

Earlier quoted context omitted.

The people naming them really took the "just give the variable any old name, it doesn't matter" advice from Programming 101 to heart.

This is why my new LLM portfolio is Foo, Bar and Baz.

Still more coherent than the OpenAI lineup.

Sam Altman's explanation for the restriction is a bit fluffier: https://x.com/sama/status/1895203654103351462

> bad news: it is a giant, expensive model. we really wanted to launch it to plus and pro at the same time, but we've been growing a lot and are out of GPUs. we will add tens of thousands of GPUs next week and roll it out to the plus tier then. (hundreds of thousands coming soon, and i'm pretty sure y'all will use every one we can rack up.)

I think it's fairer to compare it to the original GPT-4 which might the equivalent in term of "size" (though we don't have actual numbers for either).

GPT-4: Input $30.00 / 1M tokens ; Output $60.00 / 1M tokens

So 4.5 is 2.5x more expensive.

I think they announced this as their last non-reasoning model, so it was maybe with the goal of stretching pre-training as far as they could, just to see what new capabilities would show up. We'll find out as the community gives it a whirl.

I'm a Tier 5 org and I have it available already in the API.

GPT pro already has already rummored to be 100k users. You think GPT 4.5 will add to that even with the insane costs for corporate users?
