GPT-4.5 Preview scored 45% on aider's polyglot coding benchmark [0]. OpenAI describes it as "good at creative tasks" [1], so perhaps it is not primarily intended for coding.

  65% Sonnet 3.7, 32k think tokens (SOTA)
  60% Sonnet 3.7, no thinking

Maybe if they build a few more data centers, they'll be able to construct their machine god.

leave star citizen out of this :)

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…

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…

> As a result, OpenAI simply does not have a business model, even if they are trying to convince the world that they do.

They have a super popular subscription service. If they keep iterating on the product enough, they can lag on the models. The business is the product not the models and not the API. Subscriptions are pretty sticky when you start getting your data entrenched in it. I keep my ChatGPT subscription because it’s the best app on Mac and already started to “learn me” through the memory and tasks feature.

Their app experience is easily the best out of their competitors (grok, Claude, etc). Which is a clear sign they know that it’s the product to sell. Things like DeepResearch and related are the way they’ll make it a sustainable business - add value-on-top experiences which drive the differentiation over commodities. Gemini is the only competitor that compares because it’s everywhere in Google surfaces. OpenAI’s pro tier will surely continue to get better, I think more LLM-enabled features will continue to be a differentiator. The biggest challenge will be continuing distribution and new features requiring interfacing with third parties to be more “agentic”.

Frankly, I think they have enough strength in product with their current models today that even if model training stalled it’d be a valuable business.

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…

You're the one buying him the underwear. Don't index funds outperform managed investing? I think especially after accounting for fees, but possibly even after accounting that 50% of money managers are below average.

He earns his undies. My returns are almost always modestly above index fund returns after his fees, though like last quarter, he’s very upfront when they’re not. He has good advice for pulling back when things are uncertain. I’m happy to delegate that to him.

I'm one week in on heavy grok usage. I didn't think I'd say this, but for personal use, I'm considering cancelling my OpenAI plan. The one thing I wish grok had was more separation of the UI from X itself. The interface being so coupled to X puts me off and makes it feel like a second-hand citizen. I like ChatGPTs minimalist UI.

I find grok to be the best overall experience for the types of tasks I try to give AI (mostly: analyze pdf, perform and proofread OCR, translate Medieval Latin and Hebrew, remind me how to do various things in python or SwiftUI). ChatGPT/gemini/copilot all fight me occasionally, but grok just tries to help. And the hallucinations aren’t as frequent, at least anecdotally.

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

They tried a while ago: https://news.ycombinator.com/item?id=40373284 Sadly little people noticed...

Sadly few people noticed.

I don’t normally cosplay as a grammar Nazi but in this case I feel like someone should stand up for the little people :)

Finally a scaling wall? This is apparently (based on pricing) using about an order of magnitude more compute, and is only maybe 10% more intelligent. Ideally DeepSeeks optimizations help bring the costs way down, but do any AI researchers want to comment on if this changes the overall shape of the scaling curve?

Seems on par with the existing scaling curve. If I had to speculate, this model would have been an internal-only model, but they're releasing it for PR. An optimized version with 99% of the performance for 1/10th the cost will come out later.

This is the shittiest PR move I've seen since the AI trend started.

Once they've implemented saccades in the eyeballs of the characters wearing helmets in spaceship millions of kilometres apart, then it will all have been worth it.

I can chew through 1MM tokens with a single standard (and optimized) call. This pricing is insane.
