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.

Not OP, but likely because that was the only metric/benchmark/however you want to call it OpenAI showcased in the stream and on the blog to highlight the improvement between 4o and 4.5. To say that this is not really a good metric for comparison, not least because prompting can have a massive impact in this regard, would be an understatement.

A bit better at coding than ChatGPT 4o but not better than o3-mini - there is a chart near the bottom of the page that is easy to overlook: - ChatGPT 4.5 on AWS Bench verified: 38.0% - ChatGPT 4o on AWS Bench verified: 30.7% - OpenAI o3-mini on AWS Bench verified: 61.0% 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…

It's the other way around on their new SWE-Lancer benchmark, which is pretty interesting: GPT-4.5 scores 32.6%, while o3-mini scores 10.8%.

GPT 4.5 pricing is insane: Price Input: $75.00 / 1M tokens Cached input: $37.50 / 1M tokens Output: $150.00 / 1M tokens GPT 4o pricing for comparison: Price Input: $2.50 / 1M tokens Cached input: $1.25 / 1M tokens Output: $10.00 / 1M tokens It sounds like it's so expensive and the difference in usefulness is so lacking(?) they're not even gonna keep serving it in the API for long: > GPT‑4.5 is a very large and comput…

The price really is eye watering. At a glance, my first impression is this is something like Llama 3.1 405B, where the primary value may be realized in generating high quality synthetic data for training rather than direct use.

I keep a little google spreadsheet with some charts to help visualize the landscape at a glance in terms of capability/price/throughput, bringing in the various index scores as they become available. Hope folks find it useful, feel free to copy and claim as your own.

It is interesting that they are focusing a large part of this release on the model having a higher "EQ" (Emotional Quotient). We're far from the days of "this is not a person, we do not want to make it addictive" and getting a firm foot on the territory of "here's your new AI friend". This is very visible in the example comparing 4o with 4.5 when the user is complaining about failing a test, where 4o's response is wh…

The whole robotic, monotone, helpful assistant thing was something these companies had to actively hammer in during the post-training stage. It's not really how LLMs will sound by default after pre-training.

I guess they're caring less and less about that effort especially since it hurts the model in some ways like creative writing.

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 wil…

release blog post author: this is definitely a research preview

ceo: it's ready

the pricing is probably a mixture of dealing with GPU scarcity and intentionally discouraging actual users. I can't imagine the pressure they must be under to show they are releasing and staying ahead, but Altman's tweet makes it clear they aren't really ready to sell this to the general public yet.

"We don't really know what this is good for, but spent a lot of money and time making it and are under intense pressure to announce new things right now. If you can figure something out, we need you to help us."

Not a confident place for an org trying to sustain a $XXXB valuation.

I suppose this was their final hurrah after two failed attempts at training GPT-5 with the traditional pre-training paradigm. Just confirms reasoning models are the only way forward.

Sounds like it's a distill of O1? After R1, I don't care that much about non-reasoning models anymore. They don't even seem excited about it on the livestream. I want tiny, fast and cheap non-reasoning models I can use in APIs and I want ultra smart reasoning models that I can query a few times a day as an end user (I don't mind if it takes a few minutes while I refill a coffee). Oh, and I want that advanced voice mo…

Probably not a distill of o1, since o1 is a reasoning model and GPT4.5 is not. Also, OpenAI has been claiming that this is a very large model (and it's 2.5x more expensive than even OG GPT-4) so we can assume it's the biggest model they've trained so far.

They'll probably distill this one into GPT-4.5-mini or such, and have something faster and cheaper available soon.

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 wo…

The marginal costs for running a GPT-4-class LLM are much lower nowadays due to significant software and hardware innovations since then, so costs/pricing are harder to compare.
