GPT-5 Pro is genuinely a top tier model, it is the best. I know some GPT-5 reactions have been mixed (including from me), but OpenAI has made great strides with Pro. I have made 12 simulations that no other model would match, not from OpenAI, Google, xAI or Anthropic. All of them… pic.twitter.com/vzFKUttbeW

Synthetic Data Quality Reduces Compute Requirements
By

Do you think the synthetic data is relevant here? What I mean is that some effective compute has been embedded into the data to generate these high quality tokens, so you don't need as much compute to get value out of them

Stealth AI Model Adoption in Cursor Defaults Still Limited
By
