Ok this[0] sounds very, uh bold to me? Surely this is going to break a ton of workflows etc seemingly with nearly no notice? I'm assuming 'launches' equates with 'fully rolls out' or something but it's not that clear to me.

    When GPT-5 launches, several older models will be retired, including:
        - GPT-4o
        - GPT-4.1
        - GPT-4.5
        - GPT-4.1-mini
        - o4-mini
        - o4-mini-high
        - o3
        - o3-pro

     If you open a conversation that used one of these models, ChatGPT will automatically switch it to the closest GPT-5 equivalent. Chats with 4o, 4.1, 4.5, 4.1-mini, o4-mini, or o4-mini-high will open in GPT-5, chats with o3 will open in GPT-5-Thinking, and chats with o3-Pro will open in GPT-5-Pro (available only on Pro and Team).

It is frequently suggested that once one of the AI companies reaches an AGI threshold, they will take off ahead of the rest. It's interesting to note that at least so far, the trend has been the opposite: as time goes on and the models get better, the performance of the different company's gets clustered closer together. Right now GPT-5, Claude Opus, Grok 4, Gemini 2.5 Pro all seem quite good across the board (ie the…

It's also worth considering that past some threshold, it may be very difficult for us as users to discern which model is better. I don't think thats what's going on here, but we should be ready for it. For example, if you are an ELO 1000 chess player would you yourself be able to tell if Magnus Carlson or another grandmaster were better by playing them individually? To the extent that our AGI/SI metrics are based on…

We’re judging them with benchmarks, not our own intuitions.

LLMs are good at mimicking human intuition. Still sucks at deep thinking. LLMs PATTERN MATCH well. Good at "fast" System 1 thinking, instantly generating intuitive, fluent responses. LLMs are good at mimicking logic, not real reasoning. Simulate "slow," deliberate System 2 thinking when prompted to work step-by-step. The core of an LLM is not understanding but just predicting the next most word in a sequence. LLMs ar…

correlation between text can implement any algorithm, it is just the architecture which it's built on. It's like saying vacuum tube computers can't reason bc it's just air not reasoning. What the architecture is doesn't matter. It's capable of expressing reasoning as it is capable of expression any program. In fact you can easily think of a turing machine and also any markov chain as a correlation function between two states which have joint distribution exactly at places where the second state is the next state of the first state.

And what's the reasoning effort parameter set to?

Yeah I was surprised how fast they rugged 4. I guess they want to concentrate their hardware on 5.

What's the bullish case that it's actually a big deal. Not trying to be a neg, but Seems pretty incremental on first glance

GPT-5 knowledge cutoff: Sep 30, 2024 (10 months before release). Compare that to Gemini 2.5 Pro knowledge cutoff: Jan 2025 (3 months before release) Claude Opus 4.1: knowledge cutoff: Mar 2025 (4 months before release) https://platform.openai.com/docs/models/compare https://deepmind.google/models/gemini/pro/ https://docs.anthropic.com/en/docs/about-claude/models/overv...

It would be fun to train an LLM with a knowledge cutoff of 1900 or something

That would be hysterical

We'd need visibility on compute costs. If it's 30% cheaper than o3 but slightly better, that's a large improvement in just 4 months.

So only for free/plus users (for now). I do wonder how long they will take to deprecate these models via API though...
