Seeing OpenAI and Anthropic go different routes here is interesting. It is worth moving past the initial knee jerk reaction of this model being unimpressive and some of the comments about "they spent a massive amount of money and had to ship something for it..." * Anthropic appears to be making a bet that a single paradigm (reasoning) can create a model which is excellent for all use cases. * OpenAI seems to be betti…

> * OpenAI seems to be betting that you'll need an ensemble of models with different capabilities, working as a single system, to jump beyond what the reasoning models today can do. Seems inaccurate as their most recent claim I've seen is that they expect this to be their last non-reasoning model, and are aiming to provide all capacities together in the future model releases (unifying the GPT-x and o-x lines) See thi…

From Sam's twitter:

> After that, a top goal for us is to unify o-series models and GPT-series models by creating systems that can use all our tools, know when to think for a long time or not, and generally be useful for a very wide range of tasks.

> In both ChatGPT and our API, we will release GPT-5 as a system that integrates a lot of our technology, including o3. We will no longer ship o3 as a standalone model.

You could read this as unifying the models or building a unified systems which coordinate multiple models. The second sentence, to me, implies that o3 will still exist, it just won't be standalone, which matches the idea I shared above.

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…

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…

I’m not an expert or anything, but from my vantage point, each passing release makes Altman’s confidence look more aspirational than visionary, which is a really bad place to be with that kind of money tied up. My financial manager is pretty bullish on tech so I hope he is paying close attention to the way this market space is evolving. He’s good at his job, a nice guy, and surely wears much more expensive underwear than I do— I’d hate to see him lose a pair powering on his Bloomberg terminal in the morning one of these days.

It’s not a quote. It is an interpretation or reading of a quote.

Perhaps even fed through an LLM ;)

The quotation marks in the grandparent comment are scare (sneer) quotes and not actual quotation.

> Whether quotation marks are considered scare quotes depends on context because scare quotes are not visually different from actual quotations.

The announcements early on were relatively sincere and technical with papers and nice pages explaining the new models in easy language and now we get this marketing garbage. Probably the fastest enshitification I’ve seen.

Oh this makes sense. chatGPT results have taken a nose dive in quality lately. It couldn't write a simple rename function for me yesterday, still buggy after seven attempts. I'm more and more convinced that they dumb down the core product when they plan to release a new version to make the difference seem bigger.

99% chance that's confirmation bias

Sam tweeted that they're running out of computer. I think it's reasonable to think they may serve somewhat quantized models when out of capacity. It would be a rational business decision that would minimally disrupt lower tier ChatGPT users.

Anecdotally, I've noticed what appears to be drops in quality, some days. When the quality drops, it responds in odd ways when asked what model it is.

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 ava…

Holy shit, that's incredible. You should publicise this more! That's a fantastic resource.

Not if people just try a few prompts then stop using it.

Honestly, the most astounding part of this announcement is their comparison to o3-mini with QA prompts.

EIGHTY PERCENT hallucination rate? Are you kidding me?

I get that the model is meant to be used for logic and reasoning, but nowhere does OpenAI make this explicitly clear. A majority of users are going to be thinking, "oh newer is better," and pick that.

AI as it stands in 2025 is an amazing technology, but it is not a product at all . As a result, OpenAI simply does not have a business model, even if they are trying to convince the world that they do. My bet is that they're currently burning through other people's capital at an amazing rate, but that they are light-years from profitability They are also being chased by fierce competition and OpenSource which is very…

The Information leaked their internal projections a few months ago, and apparently their own estimates have them losing $44B between then and 2029 when they expect to finally turn a profit, maybe.
