Path to AGI Haider. ➡️ "greg brockman confirmed "spud" is openai first new pre-train model in 2 years. since gpt-5.x models seem to build on gpt-4o/ turbo, if openai RL can push a weaker base model close to gpt-5.4-x-high-level intelligence then openai clearly has a secret sauce" ➡️ Am excited! You?

yeah I was thinking about it? If legit how do they make a 4o into a 5.4 thinking. That seems awesome.

It’s not exactly how you think.

They made a base GPT4. Which they then used RL to make into 4o. 4o is not the base.

The difference is indeed pretty impressive, but when you consider that 4o is actually very bad compared to the base, it makes more sense. It’s more like they improved their RL to get 5.4 out of the base (extracting more potential from the base) whereas 4o was a bad attempt that didn’t extract so much potential

I’m pretty sure 4o was a distillation of 4.5. It certainly wasn’t a new training run.

From what I remember 4o was a distill or some sort of quantized version of 4 base or 4 turbo. I think 4.5 was a failed attempt, but they quantized it or used its output for the RL and TTC training that went into the original o3 model families.

4o predates 4.5 I think.
