The results for GPT - 4.5 are in for Kagi LLM benchmark too.

It does crush our benchmark - time to make new? ;) - with performance similar of that of reasoning models. It does come at a great price both in cost and speed.

A monster is what they created. But looking at the tasks it fails, some of them my 9 year old would solve. Still in this weird limbo space of super knowledge and low intelligence.

May be remembered as the last the last of the 'big ones', can't imagine this will be a path for the future.

If you want to try it out via their API you can run it through my LLM tool using uvx like this:

  uvx --with 'https://github.com/simonw/llm/archive/801b08bf40788c09aed6175252876310312fe667.zip' \
    llm -m gpt-4.5-preview 'impress me'
You may need to set an API key first, either with `export OPENAI_API_KEY='xxx'` or using this command to save it to a file:

  uvx llm keys set openai
  # paste key here
Or this to get a chat session going:

  uvx --with 'https://github.com/simonw/llm/archive/801b08bf40788c09aed6175252876310312fe667.zip' \
    llm chat -m gpt-4.5-preview
I'll probably have a proper release out later today. Details here: https://github.com/simonw/llm/issues/795

I feel like OpenAI is pursuing AGI when Anthropic/Claude is pursuing making AI awesome for practical things like coding. I only ever using OpenAI's coding now as a double check against Claude. Does OpenAI have their eyes on the ball?

>I feel like OpenAI is pursuing AGI

I don't think so, the "AGI guy" was Ilya Sutskever, he is gone, he wanted to make OpenAI "less comercial", AGI is just a buzzword for Altmann.

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…

Ah, great point. Yes, the wording here would imply that they're basically planning on building scaffolding around multiple models instead of having one more capable Swiss Army Knife model.

I would feel a bit bummed if GPT-5 turned out not to be a model, but rather a "product".

Per Altman on X: "we will add tens of thousands of GPUs next week and roll it out to the plus tier then". Meanwhile a month after launch rtx 5000 series is completely unavailable and hardly any restocks and the "launch" consisted of microcenters getting literally tens of cards. Nvidia really has basically abandoned consumers.

Altman's claim and NVIDIA's consumer launch supply problems may be related - OpenAI may be eating up the GPU supply...

OpenAI is not purchasing consumer 5090s... :)

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. The high level block diagrams for tech always end up converging to those found in biological systems.

Yeah, I don't know enough real neuroscience to argue either side. What I can say is I feel like this path is more like the way that I observe that I think, it feels like there are different modes of thinking and processes in the brain, and it seems like transformers are able to emulate at least two different versions of that.

Once we figure out the frontal cortex & corpus callosum part of this, where we aren't calling other models over APIs instead of them all working in the same shared space, I have a feeling we'll be on to something pretty exciting.

My usage has come down to mostly Claude (until I run out of free tier quota) and then Gemini. Claude is the best for code and Gemini 2.0 Flash is good enough while also being free (well considering how much data G has hoovered up over the years, perhaps not) and more importantly highly available.

For simple queries like generating shell scripts for some plumbing, or doing some data munging, I go straight to Gemini.

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…

GPT-4.5 is 15-30x more expensive than GPT-4o. Likely that much larger in terms of parameter count too. It’s massive!!

With more parameters comes more latent space to build a world model. No wonder its internal world model is so much better than previous SOTA
