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…

Because it hasn’t taken off yet as they all get to catch up

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...

Does this indicate that OpenAI had a very long pretraining process for GPT5?

Maybe they have a long data cleanup process

People always say that when new technology comes along. Usually the best tech doesn't win. In fact, if you think you can build a company just by having a better offer it's better not to bother with it. There is to much else involved.

> 400,000 context window > 128,000 max output tokens > Input $1.25 > Output $10.00 Source: https://platform.openai.com/docs/models/gpt-5 If this performs well in independent needle-in-haystack and adherence evaluations, this pricing with this context window alone would make GPT-5 extremely competitive with Gemini 2.5 Pro and Claude Opus 4.1, even if the output isn't a significant improvement over o3. If the output qu…

Needle in a haystack is not a good evaluation though - even famously bad llama 4 does well on that benchmark.

with web search, is knowledge cutoff really relevant anymore? Or is this more of a comment on how long it took them to do post-training?

Web pages become prompt, so you still need the model to analyze

I'm not really convinced, the benchmark blunder was really strange but the demos were quite underwhelming, and it appears this was reflected by a huge market correction in the betting markets as to who will have the best AI by end of the year. What excites me now is that Gemini 3.0 or some answer from Google is coming soon and that will be the one I will actually end up using. It seems like the last mover in the LLM…

Polymarket betters are not impressed. Based upon the market odds, OpenAI had a 35% chance to have the best model (at year end), but those odds have dropped to 18% today. (I'm mostly making this comment to document what happened for the history books.) https://polymarket.com/event/which-company-has-best-ai-model...

Is not that they are not impressed, is just google came out with steerable video gen

Gpt5 high reasoning is a big step up from o3

This is just more of the same. My guts tell me Deepmind will crack AGI.

ChatGPT5 in this demo: > For an airplane wing (airfoil), the top surface is curved and the bottom is flatter. When the wing moves forward: > * Air over the top has to travel farther in the same amount of time -> it moves faster -> pressure on the top decreases. > * Air underneath moves slower -> pressure underneath is higher > * The presure difference creates an upward force - lift Isn't that explanation of why wings…

You mean it's not ready for vibe physics?
